Re: [Elecraft] K4 Ethernet connection

[Thomas Horsten]

An access point will do the job, it can be set up as a simple bridge
between WiFi and wired ethernet, and you can place it as far away from your
transmitting equipment in the shack as possible and run a cable to a wired
switch that provides access for your cabled equipment.

It's very worthwhile to use shielded cat5e/cat6 cabling and grounding all
switches etc. when in an RF rich environment such as your shack.

Re: [Elecraft] K4 Remote Question

[Thomas Horsten]

I'd always say use wired ethernet (with shielded cable) in or near the
shack, a WiFi router or access point there is fine for things like your
phone and tablets, but for radios, logging/controlling PC's etc. it's way
too unreliable when you start operating. It's so annoying when your WiFi
router crashes and reboots in the middle of a contest or even just
disconnects intermittently whenever you transmit on a certain band, etc.

If you must use wireless, I'd recommend having a WiFi bridge or access
point as far away from your transmitting equipment, coax etc. as possible
and use cables from there to the rest of the shack.

Re: [Elecraft] 9:1 Balun

[Thomas Horsten]

Many manual ATU's consist of a variable capacitor and a tapped inductor.
It's a matching network but also works as an "on-the-fly" switchable balun.
The difference is the location. The ATU typically sits at the rig end where
a balun sits at the antenna feedpoint (and so may present the coax with a
better matching impedance, plus acts as a choke reducing common mode
current). You can have a remote-controlled automatic ATU at the feed point
in which case you'll always have a perfect match for your coax. Great for a
stealth multiband in the attic, but it's an expensive and clunky solution
for portable operations.

Re: [Elecraft] 9:1 Balun

[Thomas Horsten]

There's quite a lot of interesting theory in the thread, but I think for
practical purposes my original answer still covers it, under the premise
we're talking QRP with a short feedline of RG58 (a few yards).

Small autotransformer baluns like the LDG 4:1 I use (I haven't tried the
Elecraft one but I assume it's similar), are just really practical because
they have screw terminals for the LW and the counterpoise. It's pretty easy
to build your own if you really want to, but what happens inside that box
is not likely to have a huge effect on the QSO's you manage. For portable
ops, rearranging the long wire/counterpoise a bit is likely to improve your
signal more than switching from a 4:1 balun to a 9:1, or none at all.

Re: [Elecraft] 9:1 Balun

[Thomas Horsten]

Depends on your random wire and what band(s) you want to use. For some
bands the 9:1 "balun" (not used as a true balun in this case, since both
the coax and the random wire are unbalanced by nature) will step the
feedpoint impedance down to something that's a better match for the 50 ohm
coax, limiting coax losses. It can also allow your ATU to tune up on
frequencies otherwise outside its range. Use the "balun" with a
counterpoise or earth.

In some cases the 4:1 or 1:1 balun may be a better choice, or even
connecting the wire directly to the coax center conductor (and counterpoise
to the shield). All depends on QRG and wire length. If the ATU can tune it
up, you're good to go, if not, change one or more parameters until it can
(wire length, balun ratio, counterpoise length and orientation).

Re: [Elecraft] K3/100 serial 8290 - lost/stolen

Hi John,

Sorry to hear it - hope it turns up eventually! In any case does it have

(certainly wouldn't if they're stolen), but anything that would be obvious

Personally I've also ID'd my K3 and some of my other equipment internally,
so someone working on the equipment would find it but a thief trying to
sell it wouldn't. Might not get me my equipment back, but if it ended up in
the hands of an honest ham at least the thief might get caught.

Re: [Elecraft] KPA500 power fluctuations

[Thomas Horsten]

Hi Poul-Erik,

It sure sounds like a fault in the KPA500 power measuring circuit in your
case, but is the output signal affected in any way? And does the SWR LED's
fluctuate/flicker as well? I had that problem and it turned out to be a bad
patch cable from the KPA500 to the KAT500. It would only happen above 100W
or so, and on certain bands/frequencies.

 20W to 500W. It is the same with the amp ON and STBY, so it seems to be a
 problem in the power monitoring circuit.

 It is certain that the fault is in the KPA. I had another KPA connected to
 the K3 and its power indication was steady - just like they were on my own
 KPA until a few months ago. It is the same whether the amp is connected to
 a dummy load or an antenna and I dont hear anything unusual listening on a
 monitoring K2.

 I did not yet have an opportunity to look at the power envelope on an

 I thought that may be someone else on this list has seen this fault and
 might explain what's wrong.

Re: [Elecraft] Suggested key/paddle for CW for a the K3 and others (not expensive)

[Thomas Horsten]

Hi Cliff,

If you are not aspiring to be a speed demon (40WPM plus), Iambic keying
is the most comfortable and it is very easy to learn. So get a dual lever
paddle. You say not too expensive, that rules out my favorite, Begali
Sculpture, but there is a reason that the Bencher BY-1 is considered the
standard dual-lever paddles by a lot of people, and that is that it's
relatively cheap (and widely available used), and performs relatively well.
It's not a Begali by any stretch of the imagination but it's still precise
enough and has a decent enough feel that you can comfortably roll along at
25-30WPM without getting fatigued or annoyed.

So go for one of those, preferably pick it up used for $30 or so, and do
not try a Begali first or you will not want to touch a Bencher again, but
then again, the Bencher is perfectly good for what it is.

There are many other paddles around, I've tried a Vibroplex once and found
it far too clunky and with a sluggish feel, but maybe that was just that
one (it was a single-lever as well) - definitely wasn't for me.

The KXPD3 for the KX3 is great as well for what it is - it is far better
than a Bencher IMHO, and in a much smaller form-factor, of course using the
KX3 as a counterweight and not suitable for use with a K3 or any other rig.

[Elecraft] [K3] Subreceiver IF output

[Thomas Horsten]

Hi all,

I am using the K3 IF output extensively for I/Q downconversion and
panadapter display. The IF Out connector makes this very easy.

But it would think it would be very useful to have a separate I/Q stream
from the subreceiver (e.g. for monitoring a separate band, or a different
segment of the same band). I'm wondering if a mod would be possible to
allow access to the 2nd receiver IF, and if anyone has done this.

Re: [Elecraft] [KX3] Quick survey: Need a 0-dBm transverter interface module for the KX3? (KXXV3)

[Thomas Horsten]

Hi Wayne,

I think it's a great idea, but the major appeal would be if you also could
offer an ultra-portable KXXV transverter series to go with this. My
thought is something maybe half the size of the KX3, with room for several
transverter modules, like 2m, 70cm, 4m, etc. Ideally with 5W+ output on all
of those, and ideally with EXT Power (also in the KXXV3) from the KX3 so
you'd just have to hook up a single power supply to the KX3.

73, Thomas M0TRN

On 25 September 2012 03:06, Wayne Burdick n...@elecraft.com wrote:

 Hi all,

 We've had a couple of requests for a 0-dBm transverter I.F. module for
 the KX3. Normally the lowest power level the KX3 can put out is 0.1
 watts, so the I.F. module would drop the signal by 20 dB. Such a
 module could easily be designed, but there's one catch (I'll get to
 that).

 A composite RF detector on the module would provide accurate
 measurement of the RF output signal level from about -10 to +2 dBm,
 probably). The KX3's normal TUNE power display in watts would change
 to milliwatts and dBm rather than watts and SWR. (The K3 does the same
 thing when a KXV3 module is in use.)

 An SMA connector on the right side panel would serve as the
 transverter I.F. input/output. There would *not* be both RX and TX
 jacks, so all external transverters would have to have their own T/R
 path switching. We would provide a DC voltage on the SMA output jack
 (some transverters use this for signaling).

 We also plan to do transverter band switching via the GPIO signal on
 the ACC2 jack. This could control Elecraft XV-series transverters. The
 other pin on the ACC2 jack is a keying output which many transverters
 also need. Note that the XV-series can use a 0.1-watt I.F. signal, so
 technically a KXXV3 is not needed in that case. But the KXXV3 would
 allow you to keep an HF antenna connected to the BNC antenna jack
 while transverters are connected to the SMA jack. It would also
 provide better control over the drive level on bands where you've
 selected the 0-dBm output.

 The KX3 has up to 9 programmable transverter band displays, and a
 choice of 40/20/15/10/6 meters as the I.F., selected on a per-
 transverter-band basis. 10 meters is used for most trnasverters.

 Here's the catch:

 The only place such a module could go would be the same place where we
 plan to mount the 2-meter transverter, so the two would be mutually
 exclusive.

 Please let me know if you could definitely use a KXXV3. If there's
 enough interest we'll add it to the list of future options.

Re: [Elecraft] New beta K3 firmware!

[Thomas Horsten]

Hi Joe,

Thanks for that analysis! It makes the situation clear to me: The FM filter
will do just fine for AM and ESSB, and I can free up a filter slot for a
narrow CW filter.

Wayne, it would be great to have this option. I hardly ever use ESSB or AM
TX, so I can't really justify having a filter just for that if it means I'm
missing out a on 200Hz CW filter that would be really useful at times.

Re: [Elecraft] New beta K3 firmware!

[Thomas Horsten]

Hi Gary,

The point is not to widen the SSB but to use the FM crystal filter to limit
it. The DSP does the actual shaping of the TX signal which will still be
the same width regardless of whether you're using the 6kHz filter or the
12.5kHz FM one.

The idea is to be able to use the FM filter for AM and ESSB as well instead
of filling up two precious filter slots, when what you may want/need are
closer filters on the low end (say, 400 and 200 Hz).

 Joe,

 I have to ask, why?

 In VK we have a 3Khz SSB BW written into our LCD's and yet some folks
 consume 10Khz out here on a net which tears up a considerable amount of
 spectrum.

 What advantage do you see to widen the ESSB?

 Not sure I follow your thoughts here, hence the question Joe.

Seconded. I would love to have room for an 1.0 (for digimodes) and 200

 Hi Robert,

 I posted two updates, one just after I got the KXPD3 upgrade kit and
 another after I'd used it for a couple of days. These were posted on the
 KX3 group (join if you are not there already, most of the KX3 talk goes on
 there). Anyway, for those of you who haven't seen it, I'm copying the two
 updates below:

 Hi all,

 I received the field tester upgrade kit this morning. It took about 10
 minutes to install. The only problem was the size of the screw hole in the
 PCB was a bit tight, but I didn't need to drill as long as I carefully
 tightened each of the mounting bolts one turn at a time (this is a known
 problem and will be fixed in the final version).

 The kit consists of a new PCB with stainless steel fixed contacts, new
 contact screws with rounded ends, and two alternative springs to choose
 from with lower tension than the original.

 I selected the lowest tension spring and set the contact spacing at three
 quarters of a turn from the inner (fully closed) position.

 The paddles feel completely different. I tried sending some of the text
 from the upgrade instructions and didn't have a single missed dit or dah,
 and both the spring resistance and the crispness of the action is improved
 by an order of magnitude. I wouldn't say it rivals my Begali Sculpture but
 it is much closer to that feel than it was before.

 Now I just hope it stays that way, I guess with a portable rig, dirt on
 the
 contacts will be a bigger issue than for a home key, but out of the box,
 no
 complaints at all, thanks to everyone at Elecraft, you've done a great
 job.

 I did a video of my upgrade, but unfortunately my phone ran out of memory
 after 5 minutes, so the most interesting bits didn't get recorded. Maybe
 I'll post it anyway just to show the unboxing and the kit content.

 WX for the weekend is looking like we're in for a bit of Indian summer,
 with full sunshine and 27C, so I hope I'll be able to get some outdoor
 operating done with the KX3, maybe a WFF activation on Sunday. I'll report
 back after a while and see how it goes.

 73, Thomas M0TRN


 After posting my first impressions just after the upgrade, I've used the
 upgraded KXPD3 for several real QSO's and I wanted to give an update.

 My KXPD3 already had the PCB mod performed which had greatly reduced the
 intermittent contact problem. So I didn't expect the upgrade to make that
 huge a difference (only compared to the unmodified PCB which was pretty
 horrid in this respect).

 But I actually find that the upgrade kit does far more than that. It takes
 the key and transforms it from a sub-Bencher feel to a near-Begali feel.

 To get reliable operation on the paddles before, the contact spacing
 needed
 to be over 1mm. I think the main reason was the shape of the end of the
 contact screws. Per the suggestions previously made on this list, I'd
 tried
 filing down the ends of the contact screws to get them more rounded, but I
 hadn't done a very good job at it. The new contact screws are stainless
 steel and already rounded from the factory. Also the contact posts are now
 stainless steel as well. Finally, the spring tension was too high for
 comfortable operation at a very low spacing.

 So the spacing needed to be at least 1mm or so for the key to be workable.

 It's probably down to a combination of all the upgraded materials,
 including the lower tension contact spring, but the key works perfectly
 now
 with sub-mm contact spacing. I am using a spacing of about 0.3-0.5mm,
 which
 corresponds to about three quarters of a turn of the contact screws, and
 have locked them in that position. This, in combination with the lowest
 tension spring, gives an unsurpassed feel that I have only before
 experienced in my Begali Sculpture.

 I can now send clean code at 35 WPM with these paddles, something that was
 unthinkable before. Although most of my QSO's are at 25 WPM, it is nice to
 be able to send QRQ when the opportunity is there, and that's now possible
 with the KXPD3.

 The only thing I am missing slightly is individual tension adjustment of
 the left and right paddle. Since I use paddles with my left hand (but in a
 default configuration with dits on the left), I tend to use my Sculpture
 with a slightly higher spring tension in the left paddle. But in such a
 tiny key I wouldn't expect that.

 In short it's now a paddle that works extremely well and where the
 precision label is 100% justified. To be honest I thought that  was
 stretching it a bit in the original incarnation of the KXPD3.

Re: [Elecraft] KX3 DOS Program

[Thomas Horsten]

Any terminal program should do, like Telix, if you have a standard serial
port (I don't think there's any USB serial dongle drivers for DOS). Read
the programmer's manual for the commands. You probably want to enable Local
Echo in Telix.

I've written a C program that I use in Linux for a few K3/KX3 jobs, I could
probably get it to compile for DOS if you really need it, it can do things
like set the frequency and mode and read out the VFO, tell me what you want
to do and I'll let you know if I can help.

Re: [Elecraft] I/O output level

It would be easier to just hook up the KX3 to the PC with the Phones jack
to Line In on the PC. Then the KX3 has already demodulated it for you. If
you use DATA mode then it will be a raw USB or LSB chunk ready for use in
your favourite digimode program.

If you still want to listen to the KX3, use a splitter and an external
speaker and/or headphones.

By the way, the KX3-PCKT cable kit from Elecraft has all the cables you'll
need for either of these options, and is very reasonably priced (DX
shipping is only $10 but you have to ask them to use USPS 1st Class).

Thanks for the answers Joe.

So I guess there are 3 options, 1) we get a GPIO for this purpose, 2)
reverse-engineer the serial protocol and built a little interface box, 3)
Elecraft releases details about the protocol used. I'd sure prefer number 1

Re: [Elecraft] [K3] GPIO input to switch output power with external amplifier on?

[Thomas Horsten]

First off I'm pretty sure Elecraft wouldn't mind if we built this. In fact
I'm guessing if they had a cleaned up for publishing document with the
protocol specification, Wayne would post it here. I'm guessing they don't,
and it would be a lot of work to get it into a clean, publishable version -
and the engineers are quite busy with KX3, KAT500, and other things.

From a legal standpoint, there is nothing wrong with reverse engineering
such a protocol and publishing the result, as long as there wasn't any
misappropriation of trade secrets (e.g. using an unauthorized, leaked
Elecraft document as a starting point). But monitoring the communications
on the bus and from there working out the protocol, and implementing your
own version, is a perfectly legal thing to do, and is in fact a protected
right. The only exception would be DMCA-related, where you are not allowed
to reverse engineer a protocol that's specifically designed to protect
copyright - many do not like that law one bit, and it does not apply
everywhere, but in any case a case like this falls way outside the scope of
the DMCA.

So it's perfectly legal to do :)

Don,

Agree with the paper strips as a cleaning method, but I don't think there's
any case for using Deoxit on gold contacts - the gold shouldn't oxidize -
although it might dissolve some kinds of dirt that the paper doesn't get,
who knows.. but a few drops of ethanol on a paper strip would probably be
just as good.

the alternative per-band memory for drive power. It might already be there
and used for the KPA500, but I couldn't find it in the manual.

Re: [Elecraft] KX3 firmware: Vers 1.12

[Thomas Horsten]

That is a brilliant and intuitive feature, look forward to seeing it on the
K3 as well! In the normal scenario when calling CQ and you get an
off-center response, you've had to adjust RIT manually if you wanted to
keep your calling frequency (or alternatively, tap A-B, then SPOT, then
engage SPLIT).

Now it's as simple as enabling RIT and hitting SPOT. Spot on, Wayne :)

For the purpose of proving ownership in case of theft, I have my name,

Re: [Elecraft] Software CW in K3 and KX3 and contesting

[Thomas Horsten]

Win-Test is my choice for contesting. In the latest contest I used my KX3
(novelty value and wanted to try a conetst in QRP), and I missed the
automatic keying with DTR/CTS, but on the other hand had fun sending
everything with the paddles.

However, I think all of the programs you mention support the Win-Key keyer,
which also uses serial port commands and has a protocol where you can query
the buffer state and clear it.

I think (and this would be one for Wayne to answer) that it would be easy
enough to add a K(X)3 command in the firmware to allow you to query the
buffer state and/or stop sending the remaining buffer. If so, it would be
possible to add rig-controlled keying to these contest-loggers and/or write
a generic Win-Key emulator that would present as a virtual serial port and
handle the commands to the K(X)3. It would be great for the KX3 and even
for the K3 as the CTS/DTR keying has a severe disadvantage in that Windows
isn't a real-time operating system and sometimes the program will hang for
a few milliseconds, resulting in a dit turning into a dah (or a pause),
this could be avoided entirely by having the rig control the timing (as
with the Win-Keyer).

Wayne is probably extremely busy with KX3 stuff at the moment but an entry
on the TODO/IDEAS list would be appreciated ;)

Re: [Elecraft] Unhappy With Your KX3?

[Thomas Horsten]

Hi Olli,

Agree that it is marketed as a multi-purpose rig and it does it damned well
too. With external powered speakers I would expect it to be excellent and
that's my experience with it too. If it doesn't play well with the external
speakers how can it play well with headphones.

With just the internal speaker, sorry but did you actually look at the size
of that thing, considering its size it actually performs really well, but
not to hook up external speakers when used as a base station rig is IMHO
just foolish, the internal speaker is fine for operating outside on the
terrace table or out in the woods (in relatively quiet surroundings), but
if you have it in your shack then what's the big problem hooking up
external speakers and getting *excellent* audio with stereo FX and dual
watch.

The K3 has a much bigger speaker (surprise surprise) but even that misses
the stereo (essential with the sub receiver) and it's got *nothing* on my
AudioEngine A2 speakers, which I use for both my K3 and KX3 in the shack.

In general I find it nicer to operate with speakers than with headset but
for portable operations a headset is sometimes the most practical, and also
at home if there are other people in the house doing noisy things or not
appreciating the sounds from the rig.

 Hi Jim,

 well, I would not agree on that points with you. Elecraft is marketing the
 KX3 as a backpack AND desktop radio (with not available KXPA100 and
 KXAT100). They also lay some emphazise on it being perfectly for newcomers,
 etc. So I expect it to work with the internal speaker in shack situations,
 too, not only with headphones. As I would expect from any other radio, too.
 But the KX3 does the job okay in the (quiet) shack, as long as you don't
 expect it to provide sound  loudness like a stereo system. ;-)

Re: [Elecraft] KX3 Lead Time

[Thomas Horsten]

Hi Eric,

60 days, down from 6 months (I ordered mine on Dec 28 and received it in
early July), you guys have done a great job in this roll out given the
extreme demand. Imagine there's already more than 1000 KX3's out there.
Still, you've managed to keep up top notch customer service, I've had
replies to my queries within a day both times I contacted your crew (parts
team).

It's just a mind-blowing rig and you have a mind-blowing company, but I
wouldn't be surprised if the lead time goes back up once the official
reviews start hitting the masses, with the influx of orders bound to be
generated from that.

Congratulations to you, Wayne and everyone else on the team.

Re: [Elecraft] [KX3] KX3 speaker grille

Wayne,

Glad to hear it. This was my gut feeling when I got my kit, and I decided
not to follow that part of the assembly guide and leave the grille in
place. Now I'm glad I did! I'll follow whatever recommendations you come up
with for the remaining vibrations, but on my unit it's not much of an
issue, and only occurs at a very narrow range of frequencies.

I hope you'll be doing similar research as to the possible cause of the
KXPD3 issues, and I'm going to hold off trying any radical mods until I get
some conclusions from your end.

Re: [Elecraft] KX3 CW Glitch with KXPD3/keyer?

[Thomas Horsten]

Ken,

I'm a bit sorry to (mostly) agree with your points. The Elecraft folks are
certainly better rig designers than key makers. I'll say that the paddle is
usable up to maybe 25 WPM and above that it becomes too erratic. The
contact spacing needs to be far wider than what I'm comfortable with to
avoid spurious contact, and it needs to be beaten much harder than what I'm
used to.

On the other hand comparing it to my Begali Sculpture is not fair. But I
did write to Piero and ask if he'd make a paddle for the KX3, this was
before the posts in this group, and he replied that he already was working
on a prototype - I'm already signed up for it. But it would be nice if the
Elecraft key could be modified to make it a little better with close
contact spacing. Not sure if it's doable, but I'm open to any suggestions.

So far, I'm planning to try rounding the contact screws like suggested by
Wayne, and clean them up with DeOxit. Let's see how far that goes towards
helping this issue. As I haven't been able to do more portable than back
garden operations (weather only turned good this weekend!), so far I've
mostly taken my Begali Sculpture out in the garden with me, but it won't be
going with me on longer trips.

 I have similar problems with my KXPD3.  This little paddle is cute and

 I've adjusted, changed springs, adjusted, fiddled, disassembled it,

 NOTHING seems to fix the generally clunky and inaccurate sending, random
 dits or dah strings, etc.
 The KXPD3 has less finesse than my 1962 Vibroplex Bug, and needs as much
 spacing and force to operate.

 I'm fed up with it.  I'll be using my Palm paddles until Begali makes
 their Adventurer paddles available.

Re: [Elecraft] KX3 - CW glitch with KXPD3/keyer?

[Thomas Horsten]

Wayne,

When you sent out the field test firmware I reported back to you an issue
that seems very similar to this - although at the time I was certain it was
a firmware issue. But looking at it now, it could well be this issue I was
having as well, and it was just random that it hadn't shown up before I
loaded that new firmware. After that first incident where it was very bad,
I didn't have it come back at that strength. but I've seen a few
missed/delayed dits and dahs with the KXPD3. So quite possibly it's this.

Would you recommend filing off/rounding the ends of the set screws? Or take
them out and clean them with deoxit, or both?

 Steve,

 Another KXPD3 user recently pointed out something I hadn't considered.
 Some other keyer manufacturers who use cup-point set screws as
 contacts flatten (or round off) the screw ends using a fine file. This
 broadens the contact area, which can otherwise be very sharp with a
 cut point. I'm looking into whether we should be doing this in
 production.

 Please let me know if you try this on your KXPD3.

Re: [Elecraft] KX3 #687 built

Hi Steve,

Yes I was surprised at my serial no. 654, ordered on the 28th at around
noon. I'd guess they must have received several thousand orders by now and
I'd be surprised if the number doesn't surpass 5000 within a year. Once
people start seeing this rig out in the field it'll increase the popularity
I'm sure :) And we still haven't had a single review in a major magazine
yet (probably a good thing, gives Wayne and Lyle more time to iron out the
little creases in firmware).

I'm not sure what the break-even line for Elecraft is on this, but I'd be
very surprised if they're not already there by now. Hopefully that means
the talented crew will have the opportunity to create even more
ground-breaking products :)

Re: [Elecraft] KX3 Remove plastic film on display?

[Thomas Horsten]

Does this apply to the kit version? I'd have thought it was in place to
protect the LCD in transit and during handling while assembling (until it's
installed and the bezel takes over that protective role). In the factory
built version it'd be very fiddly to remove it, but in the kit it's easy
enough to remove although due care should be taken and a note to that
effect in the assembly manual might be helpful.

 the display by damaging the cover glass trying to peel up an edge.

 That's why the K3 LCD display comes without the film.

 Apparently some got shipped with the film in place by accident.

 Kevin,

 I thought that's got to be something I peel off and then as I started and
 all the segments blurred out in black as I peeled it off I thought damn,
 that was wrong, bye bye LCD. Luckily I was wrong :)

 A note in the assembly guide might provide reassurance.

[Elecraft] [OT] Bluetooth and RF

[Thomas Horsten]

Hi guys,

I know it's a bit off-topic but there are so many knowledgeable people here
that I thought I'll try asking. I've built a multifunction CW keyer with a
straight key, paddle, and keyboard input, that uses an AVR microcontroller.
Currently I'm using PS/2 for the keyboard input as it's easy to implement
in the AVR (and a cheap $2 adapter allows the use of USB keyboards).

But for taking on the road with my KX3 (which is stuck in customs since
Monday but should hopefully be with me soon), I'd like to use an
ultra-compact Bluetooth keyboard, of the type used with smartphones. I am
considering doing this by adding a Bluegiga WT12 Bluetooth module (which
has an UART interface that can talk to the AVR).

Before I begin on this I'd like to know how well Bluetooth can be expected
to work in a RF-filled environment (at up to 10W but with the antenna very
close, as in portable operations). It'd be a shame to get everything built
only to find out that the Bluetooth connection dies every time I transmit.
Has anyone got experience with this and/or other comments/ideas?

Re: [Elecraft] K3 for CW

[Thomas Horsten]

Vic,

You may say this and it may be true in theory, but if you have a 400Hz
filter and are listening on an otherwise clear segment of the band with a
single relatively weak signal in the centre of the passband, try widening
from 400Hz to 450Hz, in my case switching to the 2.1kHz filter. If you
still believe there is no reason for the narrower filter, IMHO you need
your hearing checked [no offense intended]. Or try telling the K3 that it's
really a 500Hz filter and do the same from 500 to 550Hz, same effect.

Personally I have not had any need for anything narrower than 400Hz,
although I would love a 200Hz filter if there was room for 6, but my lineup
is FM, AM 6kHz, 2.7, 2.1, 400, so I don't have room for any more.

73, Thomas M0TRN

 The ONLY time you need a narrower filter is when there is a signal that is
 about S9+20 or
 greater that is outside the DSP bandwidth that you have selected but still
 within the
 bandwidth of the selected filter.

Re: [Elecraft] 4.48 vs 4.51 CW Decode

[Thomas Horsten]

Hi Wayne,

Since the effects of 4.51 have come up again, I'm wondering if you got
around to investigating the (to my ears negative) effect on APF that it
brought on? I seem to remember you were going to do some measurements, but
I can't remember having seen the results of those.

 CW decode can and will be improved in the next release after 4.51. But
 we have to get 4.51 into production status because of the AGC

4) Requires constant adjustment of the RF Gain control
 
  This was  the absolute best CW decoder I had ever used. I am still
  using 4.51 but have not yet hit the sweet spot with it. Perhaps

  I am can copy call signs, signal reports at elevated speeds, but

Re: [Elecraft] CW Key suggestions ?

[Thomas Horsten]

Jim,

Can only second that, I love my Begali Sculpture. It replaced my first
paddles, a Bencher, which fades rather in comparison.

Incidentally, I took it with me on a trip to Denmark with my FT817, but
only that one time, after that I've travelled lighter :) When I get the KX3
I will take that and use the built-in paddles, the Begali Sculpture is
really not suitable for portable operations but it is just such a great key
you feel like taking it along in spite of its weight.

 I ordered a Think-tank Strobe Stuff bag from Amazon (about $45). It
 just arrived, and in my opinion this is the ideal bag for anyone who
 wants to carry a KX3 and accessories in the smallest possible form-
 factor.

 You could even use this bag for Ultra-light HF Pack operation
 (pedestrian mobile). Just strap it on and deploy the whip out of the
 top of the bag. There's a way for mic and headphone cables (and a
 trailing ground wire) to emerge from the bag while it's fully zippered
 shut.

 (I also need to write some new firmware that allows you to hold both
 mic buttons together to switch their function from VFO control to
 volume control :)

 The LowePro Edit 140 bag, which I also have, and Rose Kopp's KX3
 bag, both have a lot more space when you need it. But sometimes I like
 to travel really light.

 Here's a rough dimensional comparison (HWD) of the two camera
 accessory bags:

   Edit 140:  6 x 11 x 7.5 (total volume, about 500 in^2)

   Strobe Stuff:  4 x 9.5 x 4.5 (about 170 in^2)

 The Strobe Stuff bag is much smaller, but still holds everything you
 need for a complete station:

   KX3
   MH3 mic
   backup mini-mic (3 long, hinged, with 3.5 mm plug)
   KXPD3 keyer paddle
   ear buds
   spare set of 8 AA cells (or a 4-cell, 14-V Li-Ion pack)
   antenna and ground wire (two 25' lengths of Wireman #26 silky)
   two 1 stainless-steel hex nuts (for tossing wire into a tree)
   20-m two-piece telescoping whip (in case there isn't a tree)
   BNC L
   BNC-to-binding post adapter (for use with the wires)

 I put the KX3 and the antenna wire in the main pocket, spare batteries
 in the small accessory pocket on the bottom of the bag (4 x 4 x 1),
 and everything else in the large accessory pocket (4 x 10 x 1).

 The Strobe Stuff bag has a few other features:

 - The small zipper pocket at the bottom normally holds a rain fly that
 can be pulled out and secured over the entire bag to keep it dry. But
 I pulled the rain fly out in favor of the external battery pack or
 spare AA cells.

 - At the top of the bag there's a small fabric loop you could use for
 hanging or carrying, and two smaller loops that could serve as strain
 relief points for wire.

 - On the back there's a T-shaped fabric strap with lots of velcro that
 conceals a hinged strip of very sturdy plastic. This strip reinforces
 the fabric strap, so the bag can be attached securely to a belt or
 backpack. The strip also seems to function as a tilt-stand for the bag
 if deployed at an angle. This probably has some utility when used with
 camera strobe lights.

 I'll be testing the bag this weekend (Field Day).

 Wayne

[Elecraft] [OT] Account of DJ6SI's arrest and maltreatment in Greece for ham operation

[Thomas Horsten]

Hi all,

I was planning to go on holiday to Greece this autumn/fall and operate with
my KX3 from an island hotel. But after reading shocking Baldur's story I
have changed my mind. I'll find another holiday destination. I'm forwarding
this report, from The Daily DX, with the permission of Bernie McClenny.
Just in case anyone else has plans to go to Greece and operate, I would
suggest you take precautions (e.g. by contacting the Greek authorities in
advance, or choose another country to operate from).

Bernie asked me to mention that a majority of the SV ops are outraged by
this incident, and it should not reflect badly on the Greek Amateur Radio
operators. I can only agree that Greek ham operators (and the Greek public
in general) are among the friendliest people I've encountered. As for how
it reflects on the Greek authorities, judge for yourself.

DJ6SI – Report on the arrest in Kos, Greece
 By DJ6SI, Baldur Drobnica
  Translated by DF3CB, Bernd Koch
__

I booked a holiday trip break of one week on the island of Kos in
Greece in May this year. I took a HF station with me to give some
DXers new band points or even a new country. I could install a G5RV
with the permission of the hotel management.

After three days, at 01 in the morning, my XYL DL6KCD and I were
woken up by an attorney and five police officers in civilian clothes.
My wife is suffering from Alzheimer and has three bypasses. I was
accused of conducting radio communications without a Greek radio
license. The second accusation was that I could also watch other
frequencies with my transceiver, a FT-890AT. My objection was
rejected that I operate legally on base of the CEPT regulations. The
hotel manager printed the CEPT list which is available on the website
of the DARC and handed the printout out to the attorney. The paper
was ignored, folded and put into the pocket. My transceiver was
confiscated together with the power supply and the headphones with
the remark that it had to be checked by a specialist. They also tried
to confiscate my notebook which I tried to defeat because the
notebook was not related to the transceiver that had to be checked.
Two mobile phones, cameras and the log book were also confiscated; we
were handcuffed and taken to the police station. The handcuffs were
so tight that they cut into my flesh and draw blood.

I was taken to a hospital where the wound my on hand was treated. In
absence of a prison cell, the police wanted to put me into a drunk
tank but the attending physician declined that. So I had to spend
four hours at the police station sitting on a chair. My hint that I
had to see my un-oriented wife was rejected by saying that she is
enclosed in the (hotel?) room and being closely guarded from outside.
After long discussions I was then escorted by two police officers to
visit my wife at the hotel, medicate and dress her. Personal care and
showering, was rejected. Back at the police station a protocol was
created.

Then we were driven to the courthouse. It was now 11AM. I was
photographed and fingerprinted in the courtyard of the courthouse.
Then we waited again until 4PM under police protection, when I was
presented to the attorney who explained me the charges in a two-
minute talk: transmitting without permission, having a radio with
frequencies other than intended for amateur radio operators and the
hindrance in handing out my notebook.

I was commissioned to the court for the next day at 12:00. I had to
wait until 16:00 until a judge and an attorney came. The judge told
me that he had no translator and appointed a new proceeding for the
next day at 12:00. When I objected that we had to fly back the next
day, he explained: “this is your problem”. Finished.

I called the German Embassy in Athens on the morning of the next day
and got the notification of the German-speaking lawyer on Kos. We met
an hour before the opening hearing. My luck was that he was once
interested in amateur radio. I handed him the documents that were
kindly printed out by the hotel management had kindly printed for me:
CEPT regulations of the DARC and this also in Greek language. The
hearing was very noisy and the objection of the attorney, he would
turn to the European Court, the judge adjourned the hearing, let me
go back to Germany and decreed that the lawyer could attend the next
hearing alone.

My wife and I had not taken any food for sixteen hours; it was not
even offered us. I had no way to sleep for 34 hours. All this as a
consequence of an anonymous tip that I had been working without
authorization and that I could hear other transmitters. The
prosecution referred to a charge on a law dating back to the year
1929!

 listening to Youtube videos I've checked out, where people are fixated on
 demonstrating the adjacent signal rejection qualities of the K3 (the
 feature
 most often, and justifiably according to all the articles and posts I've
 read, touted for the K3).  Is the tonal quality I love in my K2 a
 function of
 it being an analog receiver, something I'll have to forgo to obtain the
 better selectivity of the K3, or is the difference I appear to notice
 just a
 function/artifact of the Youtube videos I've been watching?

  Not trolling for a flame here; it's just I'm not a contester and am not
 really interested in giving up any of the listenability and other features
 that make my K2 so much fun to use just to get the ability to reject
 strong
 adjacent signals;  I'd like to be able to have all of the superior
 selectivity and noise reduction features of the K3 without having to give
 up
 any of the great qualities of my K2, and need to get a warm and fuzzy on
 this
 point before making the considerable investment in a K3.  Again, thanks in
 advance for any helpful observations you can offer!

Re: [Elecraft] [K3] MON on headphones only please?

[Thomas Horsten]

Gary,

I wouldn't want to disallow it for anybody, I'd just like the option to
have MON to 0 for when the speakers (external or internal) were on, perhaps
by having two different memories for the MON level, one when speakers are
on and another when they are not.

 or are you meaning this action would only apply to the K3 internal speaker.

 I have MON set @4 all the time, headset or desk mic.

Re: [Elecraft] UK Re-seller

[Thomas Horsten]

If I was to make the journey all the way to WS I'd probably end up picking
up something. But I can't see anything wrong with going to look at
something in a shop and then buying it off the Internet, I do it all the
time, if they charge a lot more than online. If there's a small premium,
it's worth it for getting the item immediately, but if they are making a
30% profit or so, no thanks.

I don't think there's anything wrong about doing this at all. What I've
done successfully in the past though, is go to a store that has something I
want, confront them with the online price, and end up getting a good deal
from the shop (a bit more than the online price but getting the item
straight away).

 If you want a local shop to be there when you need something at a

 costs a little more, that is the price of keeping him in business.  I
 will admit that if the price difference is too great you are

 The advantage is you can go to WS, look at and try the rig, then
 purchase it direct from Elecraft!

Re: [Elecraft] Rev 4.51 firmware - what AGC settings worked on big pile-ups with loud AND weak signals in the WPX?

[Thomas Horsten]

Hi all,

I also used the 4.51 firmware during the WPX test. Settings as default
except THR 10 and SLP 8. I worked a lot of weak stations (BA, JP, VK etc.)
near louder ones, from 15m down to 40m, and around a hundred EU stations on
80m. On 15 and 20m with PRE on, on 40m with PRE off and on 80m with ATT on,
and with the RF gain mostly turned all the way up except on 40 and 80.

It worked great and I was able to copy all stations who could copy me. I
love my K3.

 Antenna SteppIR beam.
 The weak signals shone through, I could pick out the JA and weak BA's over
 the EU crowd. NO CLICKS
 The only noticeable effect i could detect was a distinct hollowness in QRQ
 running at 35wpm, but this could have been an effect of condx's,  the other
 thing was QRQ is disabled with RIT ON and defaults back to QSK!!

 More testing this weekend during RSGB NFD and Region 1 FD for a tweak or

Re: [Elecraft] Buying a K3 in the UK?

[Thomas Horsten]

I'm also going to keep dealing direct with Elecraft, although I'll keep an
eye on the prices from WS. But think about it this way, Elecraft starting
to have regional distributors around the world is enabling them to grow
much bigger because they can reach a more mainstream market segment who are
not comfortable with buying online from abroad.

The more money Elecraft is making from its existing products, the more
people Wayne and Eric can hire to help them make even more great Elecraft
products.

 In general establishing a parts depot in each country (or common trading

Re: [Elecraft] KX3 Order Number Decoding

[Thomas Horsten]

For those who have access to a Linux command line with Perl installed you
can do the conversion in this oneliner:

Just insert the first 8 digits of your order number (with the dash removed)
instead of the example of 22084064. E.g. if your order number was
2209-4362-1234 you would use 22094362.

Then run:

perl -e 'use POSIX qw(strftime); print strftime(%a, %d %b %Y %T %z\n,
gmtime(22084064*60));'

The output will be in UTC and look like this:

Re: [Elecraft] Spurs on 15m from new laptop

Hi Barry,

You might want to try a different HDMI cable with better shielding, like
this one
http://www.amazon.co.uk/AmazonBasics-Quad-Shielded-High-Speed-Cable/dp/B002C1BHIO


I haven't tried it myself but they claim it's quad shielded.. But it
could also be the monitor's HDMI decoding circuit creating the spurs in
which case it probably won't help. Try moving the cable around?

 When I unplug the HDMI cable, noise stops.  I'll wrap the HDMI cable with

[Elecraft] [K3] K3 and noise with external speakers

[Thomas Horsten]

Hi,

I like to alternate between operating with headset and speakers and find
the K3's built-in speaker inadequate (plus I want stereo). So I purchased a
pair of Audioengine A2 speakers (black, and with the corresponding desk
stands, wonderful little speakers I must say and they look GREAT next to
the K3 - judge for yourself: http://goo.gl/KErTo)

Now the problem is that I have been running with AGC=LOW since it gives me
a comfortable range in the headset. The speakers have a volume control on
the back, so I thought I could adjust that to get a volume that was similar
in the headset. The problem is that with a low enough AF volume setting on
the K3 that the headset isn't blasting my ears out, and the speakers volume
set to give a similar level to that of the headphones (about 66% of their
max), the speakers give a very noticable very low frequency bassy click
once a second anytime the K3 is turned on.

It's like thump, thump, thump at one second intervals. This is loud
enough to be noticeable when the speakers and the headphones are at about
the same level for the real audio. If I turn the speakers' gain down and
turn the K3's AF knob up, I get FB loud enough audio without hearing this
problem, but with a low enough volume in the headset for it to be
comfortable, I have to turn the speakers up where the thump gets
noticable to get rid of it again.

I'm powering my K3 from a car battery that is in turn hooked up to a smart
charger. This has never caused me any problems in the past, but it would
seem that this artifact comes from the smart charger somehow, as soon as I
disconnect it the problem goes away and I can have the speaker volume all
the way up to max without hearing it.

As I said I've never had any audio (or other) problems before from having
that battery charger connected. Any suggestions for what to try next would
be appreciated.

Re: [Elecraft] [K3] K3 and noise with external speakers

[Thomas Horsten]

Hi Art,

I totally have that problem as well, but I was more bothered by the other
one for now so that's why I wrote about it. It would be amazingly nice if
you could have the MON level track the AF level. In fact, it would be a
killer feature.

 My speaker approach was a pair of formerly rear speakers in a surround
 sound system - SONY in this case. Having stereo speakers provides (most of
 the time) the same effect as stereo headphones - when the sub-rx is on, DX
 from the left side and pileup from the right side - although it's easier to
 work through the pileup with phones.

 My problem is  not with the speaker/phone volume, but with the monitor
 (sidetone) volume. When it's set more-or-less normally for speaker use,
 it's much too loud for use with the cans on.

 My daily (and therefore also for DX) logging program is DXLabs. Commander
 provides a host of User Defined Controls - one of which I use to alter the
 monitor level - significantly lowering it before slapping on the
 headphones. Then, the second push, when I'm finished, restores MON to the
 old level.

Re: [Elecraft] [K3] K3 and noise with external speakers

[Thomas Horsten]

Hi Dwayne,

I already use the macros, I have PF2 set to toggle SPKR+PH on/off so I can
turn the speakers off when I'm wearing the headset (PF1 is set to
enable/disable ESSB, and could be considered a spare since I hardly ever
use ESSB).

But the problem is that in CW I like to operate with both speakers+headset,
so I can put the headset on if I hear something interesting and want to
copy it better (over the noise of the linear and other ambient noise). For
stronger signals, I just have the QSO with the speakers and not the
headset. Of course for SSB I need to wear the headset if I don't have the
desk mic out, but then SSB is only about 10-20% of my QSO's.

When I get my desk mike out again, I think I will reprogram PF1 to switch
between the front mic/headset as you suggest.

Actually if I can find a solution to the speaker noise problem, I think
everything will be ok. The only other thing is what Arthur mentioned and I
elaborated on, the MON level. It is hard to send CW if the MON tone is too

noise) when I'm on the speakers, but MON doesn't follow. So if MON could be

 Thomas,

 You might want to consider using a macro to adjust the monitor level? At
 the
 same time, you can change the EQ and other settings to suit your needs.

 I use two macros to control microphones, speakers and TX EQ. They are
 assigned to PF1 for the hand mike and PF2 for the headset/boom mike. The
 last line in these macros changes the monitor level, OFF for speakers, and
 ON for headphones. Adding code to change RX EQ might also help you reach
 your goal of getting the volume where you want it.

 To use these macros, press and hold PF1 to use the hand mike; press and
 hold
 PF2 to use the headset/boom mike. Pressing either PF button a again toggles
 the speakers ON and OFF.

  Hi,
 
  I like to alternate between operating with headset and speakers and

  purchased a pair of Audioengine A2 speakers (black, and with the
  corresponding desk stands, wonderful little speakers I must say and
  they look GREAT next to the K3 - judge for yourself:
  http://goo.gl/KErTo)
 
  Now the problem is that I have been running with AGC=LOW since it
  gives me a comfortable range in the headset. The speakers have a
  volume control on the back, so I thought I could adjust that to get a
  volume that was similar in the headset. The problem is that with a
  low enough AF volume setting on the K3 that the headset isn't
  blasting my ears out, and the speakers volume set to give a similar
  level to that of the headphones (about 66% of their max), the
  speakers give a very noticable very low frequency bassy click
  once a second anytime the K3 is turned on.
 
  It's like thump, thump, thump at one second intervals. This is loud
  enough to be noticeable when the speakers and the headphones are at
  about the same level for the real audio. If I turn the speakers' gain
  down and turn the K3's AF knob up, I get FB loud enough audio without
  hearing this problem, but with a low enough volume in the headset for
  it to be comfortable, I have to turn the speakers up where the
  thump gets noticable to get rid of it again.
 
  I'm powering my K3 from a car battery that is in turn hooked up to a
  smart charger. This has never caused me any problems in the past, but
  it would seem that this artifact comes from the smart charger
  somehow, as soon as I disconnect it the problem goes away and I can
  have the speaker volume all the way up to max without hearing it.
 
  As I said I've never had any audio (or other) problems before from
  having that battery charger connected. Any suggestions for what to
  try next would be appreciated.

Re: [Elecraft] [K3] New order, do I need a KAT3

[Thomas Horsten]

Hi Tony,

I don't have the ATU in my K3 and I am quite happy without it. I have
mostly resonant antennas (2.0:1 on the bands I use without ATU) and do
have a manual external tuner that I can put in for the other bands.

If you are using a remote ATU at the antenna feed point there's no need to
have the KAT3 as long as the SWR seen at the rig stays below 2.0:1 (ideally
1.5:1), beyond that the K3 protection circuitry scales back the power.

If you're planning to use the K3 for portable operations then getting the
ATU is probably a good idea. Then you can just hook up any wire antenna,
possibly fed with balanced feeder and a balun, and you'll probably be able
to get a good match on all bands. For that reason, I'm getting the ATU in
my KX3, but I don't think I'll add it to my K3.

Re: [Elecraft] New K3 Firmware: Improved AGC (great for pile-ups as well as general operation)

[Thomas Horsten]

Wayne,

It's hard for me to do a before/after side by side comparison since I only
have one K3 and the band conditions change all the time, but after using
the 4.51 firmware for a couple of days, it seems to me that APF is maybe
slightly less effective than it was before. Maybe it's because the overall
clarity of the weak signals is generally improved, or else the AGC changes
somehow interact with the APF in a detrimental way?

I'm generally using the 400Hz filter for CW and adjust the passband down to
about 250Hz for best readability on weak signals, engaging APF at that
setting previously made most weak signals much louder, now it seems to make
that much difference only on a smaller subset of signals and only when the
band is relatively quiet.

It could well be down to random band condition changes before and after the
upgrade, but I thought I'd mention it anyway.

 K3 beta-test firmware revision 4.51 (with DSP rev. 2.76) is now

 The most important change is that the K3's AGC threshold (CONFIG:AGC
 THR) can now be set much higher. In addition, the AGC now has very
 precise response on attack/decay (monotonic, not scalloped). The
 combination of these changes can greatly improve signal clarity in
 pile-ups and other high-noise or dense-signal situations. Many
 operators have also reported improved effectiveness of noise blanking.

 With this release, NR and Auto-Notch can be used at all of the new

Re: [Elecraft] K3 AM receive question

[Thomas Horsten]

Hi Stefan,

You can listen to AM (in AM/AM-S) mode with the 2.7kHz filter FB. But the
wider rx that the 6kHz filter provides gives a very noticeable improvement
in audio on the broadcast stations. My K3 (bought second hand) came with
2.7kHz filter and no general coverage RX filter, since I am also interested
in SWL I ordered both the 6kHz AM filter and the general coverage filter, I
have to say it makes a huge difference for AM listening with those two
installed (obviously the further you get away from the ham bands, the
greater the difference for RX sensitivity).

Listening to talk radio with the stock 2.7kHz filter is tolerable, but
after installing the wider one I find myself listening a lot more to the
shortwave broadcast stations.

Needless to say the audio is great, I'd say acceptable from the built-in
speaker but with my added Audioengine A2 desktop speakers it makes for a
classy listening experience.

But try with the stock filter and judge for yourself, you can always order
the wider filter later, installing it is easy. Depending on how much of a
priority shortwave listening is to you, you may or may not decide to get
it, it's perfectly acceptable quality in AM-S mode with the 2.7kHz filter
for voice transmissions.

Re: [Elecraft] put together for kx3 kit?

Last I heard (middle of last week?) they were still putting together the
kit assembly manual, and making minor modifications to the hardware. I am
sure there will be a reaction when the kit manual becomes available for
download, both here and on the KX3 group.

I too am quite curious about this, I am expecting it to be a 2-3 hour job
and probably a bit tricky in places, considering the amount of electronics
squeezed into that small space. I'm expecting at least 4-5 boards including
the ATU and battery charger.

Re: [Elecraft] [QRP-L] The Chinese KX3

[Thomas Horsten]

The only way they will come anywhere close to the KX3 performance is by
pirating large portions of the KX3 hardware design and firmware. If that's
the case I hope they don't succeed.

Besides, if they try to add all the same kinds of features that the KX3 has
it will probably be full of bugs and I am sure you won't get the same kind
of support that you do from Elecraft, where the developers actually listen
to the users. At best, it will be a pale imitation of the real thing and at
worst it will be an epic nightmare of bugs and trying to deal with sporadic
support announcements in Chinese with Google Translate as your only friend
when trying to figure out what's going on.

But to be honest, looks like a spoof to me. A well made spoof, but still a
spoof.

Re: [Elecraft] [QRP-L] The Chinese KX3

[Thomas Horsten]

Jim,

What exactly is absurd about the add on costs that Elecraft charges, in
your opinion ???

That's the statement that sticks out to me as being absurd in your mail.
You buy the accessories you want/need and add it up. The total KX3 price
after doing that doesn't seem absurd to me. Not extremely cheap either, I'd
agree, but most certainly not absurdly expensive.

There are Chinese knock-offs of many product categories. Generally, the
Chinese versions are reasonable value for money but the equation generally
does include a much lower build quality and feature set and a much lower
support level.

To take the Wouxuns for example, they are great rigs for the price, but the
more expensive ones from Yaewoodcom do have a definitive edge on quality
and how well they are thought out. It's just questionable if they are worth
paying so much extra for, and personally I'm happy with my Wouxun. But for
something as primary to my ham operating as my main portable HF rig, I
won't settle for such a compromise.

Re: [Elecraft] K3 Filter questions

[Thomas Horsten]

Dave,

1.

I prefer the 2.1 filter for SSB, 1.8 can potentially give a slight edge
when the bands are extremely crowded, but generally speaking I use the 2.7
and narrow down to 2.1 if there is much QRM, remember that with the DSP you
can go as low as you want, so it only makes a real difference if the
interfering signal is way stronger than the one you want to copy.

So in the end I swapped my 1.8kHz filter for an extra 500Hz filter for the
sub receiver.

2.

I haven't tried the 2.8kHz 8-pole filter, it has sharper edges than the
2.7k one and some people prefer it. I have the 6kHz 8-pole filter as well
(for ESSB/SWL broadcast listening) and if the transmitting station is using
a wide TX filter for SSB it sounds better with that in. Again, the DSP does
a lot of the work so I don't think there is that much difference between
the 2.7 and 2.8 filters, if I was to buy a new rig I'd probably opt for the
2.8 one, but not a strong preference. I think the main difference is
slightly sharper edges on TX, and negligible on RX.

3.

I have found the 400Hz filter perfectly adequate for CW and digimodes. A
1kHz filter would be much more useful, and I will probably get it
eventually, but the 250Hz filter doesn't seem that useful to me. 400Hz
gives enough of a context to make a weak CW signal stand out particularly
when APF filter is on. For digimodes, I've copied a few PSK31 signals that
I could not copy with 400Hz because it was drowned out by a very strong
signal elsewhere in the passband, but I've never had this happen with a
signal that was less than 400Hz away, remember you can adjust the width and
center frequency independently and the K3 chooses the best crystal filter
for the job, so you can move the rx window left or right to avoid any
interfering strong signal close to the one you want to copy.

All in all I'm very satisfied with my filter lineup which is:

Main RX:
FL1 - None yet (KFL3B-FM 13kHz FM filter on order, for operating FM on 10m
and with transverters in the future)
FL2 - KFL3A-6K (for AM/ESSB receive (and rarely used ESSB TX))
FL3 - 2.7kHz 5-pole filter
FL4 - KFL3A-2.1 (for SSB and digimodes)
FL5 - KFL3A-400 (for CW and digimodes)

Sub RX:
FL1 - None
FL2 - None
FL3 - 2.7kHz 5-pole filter
FL4 - None
FL5 - KFL3A-400

I wish I had room for 1 more filter, so I could have the 1kHz filter for
use with wider digimodes and a wider PSK31 passband. Most of the time for
PSK31 it is not necessary to go down to the 400Hz filter to copy the
weakest signals, but 1kHz would be better when the bands are crowded. I
don't think a 250 or 200Hz would confer any real advantage.

Re: [Elecraft] K3 Filter questions

[Thomas Horsten]

I haven't looked at the spec for the 1.8 filter but I second what Dave was
saying, the specified filter bandwidths are (I think) -3dB and the curve is
obviously not completely straight down, so there is still signals outside
the passband.

I have told my K3 that the 400Hz CW filters are really 500Hz, which means
the 2.1kHz filter only kicks in when I move above 500Hz, which allows me a
slightly wider passband e.g. when calling CQ, this works extremely well for
me, and from looking at the waterfall the extra 50Hz on each side are
getting through the filter well enough.

I'm sure operating the 1.8kHz filter as a 2.1 one would work as well,
although I never tried it myself, it might actually be a better setup than
the 2.1 filter for contest use.

 I used the 1.8 for the entire WPX SSB contest, with a DSP width
 of 2.1 KHz.  It sounded great.  I never messed with any of the
 settings for the entire contest.  To get this combination of
 DSP=2.1 and crystal=1.8, one has to install the 1.8 filter as if
 it were a 2.1, so it switches in at DSP=2.1.  This installation
 setup is most easily done using the K3 Utility.  In practice,
 normalize, then use high cut until the filter switches in.  To
 me, the audio sounds best using that technique.  WPX SSB is
 traditionally the worst-case QRM-fest, and the 1.8 filter was
 just the ticket for dealing with it.

 From experience, I had both the 2.1 and 1.8 fitted and by
 judicious use of
 the Hi Cut/Lo Cut adjustment I find the 1.8 far better in

Re: [Elecraft] K3 reset/reboot

Try restoring an old configuration and/or upgrading the firmware with the
K3 utility from a PC. Sounds not so good to me though...

 The K3 has been sitting off the operating table for a couple of months

 the display looks ok, none of the buttons function as they should. Most of
 them do nothing, others are mis-mapped, i.e. Mode ^ toggles ANT1/2, Mode
 (dwn) toggles RX/ATT, XMIT turns the preamp on and off .

 Tried the Shift/Power Up trick to reset and no joy. Of course it doesn't
 respond to any serial communications Checked the internal coin cell and
 its ok ...

 Any tricks I'm missing? Hopefully not a trip back to the mothership.

[Elecraft] Elecraft on Wikipedia

[Thomas Horsten]

Hello all,

I noticed about a week ago that Wikipedia didn't have an article about
Elecraft, even though it's definitely a notable company in the ham
community, so I decided to fix the problem by creating one:
http://en.wikipedia.org/wiki/Elecraft

It is currently a stub article, with limited information, and I don't
really have time to evolve it into a full article by myself, but here's
inviting those on the list knowledgeable on the subject to have a go at
improving the article.

Please keep in mind that edits to Wikipedia articles must adhere to the
Wikipedia guidelines, most importantly Neutral Point Of View, articles
that are deemed blatant advertising or unduly glorifying/vilifying the
subject of the article or relying on unsourced material are at risk of
being deleted. In general, facts should be backed by reliable third party
references (for products this could be reviews in established magazines or
similar).

It may be helpful to compare with the articles of other ham equipment
manufacturers to get inspiration.

73 and happy editing,
Thomas M0TRN

[Elecraft] [K3] Feature request: MON in headphones only when SPKR+PH=yes

[Thomas Horsten]

I guess the subject line says it all - I would like to hear my audio
feedback in the headphones but not through the speaker, so as to not create
distortion/feedback, I wonder if it could be done in the firmware, if it's
possible, I'd appreciate an entry on the todo list :)

Any comments/suggestions?

 However, if you notice the shutdown behavior of the speaker amplifier
 it does not turn off instantly and generates a lot of distortion during
 the process.  That ramp down and distortion would be very annoying.


If that's the case then of course it wouldn't make sense to do.

 haven't noticed that effect on my K3 and actually when just tested it now
I don't hear anything other than a very faint click when the speaker
switches off (I have PF2 programmed to toggle SPKR+PH). Maybe it's only on

 Elecraft KX3: Field Tester Review of S/N 6
 All-

 Attached is a photo of KX3 #6 [actually not--see note above--WB].
 It's an outdoor shot with the backlight off.  This unit is in Field
 Test here, which is its own type of milestone for all those waiting
 patiently.  I'll be writing objective appraisals of this FT unit.
 That will be my intent, anyway (objectivity).  This email is a first
 cut.  Read on.


 My personal opinion is that this is the coolest amateur transceiver
 ever designed, built, or dreamed of.  Perfect size, perfect weight,
 VERY respectable performance.  You can *really* take the KX3 with you,
 and you’ll really want to.  Mine’s going everywhere with me, including
 the workplace!  I know my engineering staff will demand to see how
 Wayne and crew fit it all in, and how well the KX3 works.


 After one day using this unit, I've reached the conclusion that the
 KX3 is basically ready for initial production.  As is usual for a
 'young' rig from Elecraft, firmware is still a work in progress.  This
 should be no surprise to anyone on this list.  The hardware is at
 near-100% shape, IMHO.  There are a few minor issues - mostly features
 not yet implemented.  And I mean minor.  If I weren't an engineering
 manager in the consumer products industry I would not have noticed any
 of them.  The electronics seems solid, and I've done a bit of lab
 testing for MDS and selectivity.  Most of my testing has been on the
 air though.  My lab testing shows MDS better than -136 dBm, but my
 signal generator can't extend any lower.  No problems with rejecting
 out of band signals (away from the roofing filter's coverage).


 On the air:  I've had about fifteen CW QSOs, using between 1 and 12
 Watts output power.  The antenna is a homebrew multi-band vertical,
 ground mounted.  Four of these Qs were on battery power.  No
 differences were found between operating on external and internal
 power, except for the output power limitations due to batteries.  One
 Q was with an extremely weak QRP station in New Mexico.  The APF
 helped with this, to the point that I could not have pulled him out
 without the feature.  With APF engaged, his signal was 539 with rapid
 fades to 319.  He was running 0.5W and I was running 3 W.  Great
 ragchew, with very few repeats.

 Except for Navy-Marine Corps MARS, I'm mostly a CW op.  Several SSB
 contacts went successfully after a false start: I had to finagle the
 MH3's input connection a bit (a virgin socket seating issue).  I set
 the MIC and CMP values by listening on a second receiver and built in
 MONitor, giving  MIC=18 and CMP=10 as the best combination.  Audio
 reports using the MH3 and this setting were excellent - clear as a
 bell and good presence”.  Output using the internal speaker is
 adequate, though not amazingly loud.  Some of that is probably my 55
 year old ears and too many rock concerts when I was younger.  The
 frequency response seems relatively flat and lows are surprisingly
 well-represented.  Distortion is low ( 2% THD the way I hear it).

 The FOC and NA contests run this weekend were an interesting
 environment for first-time ops on the KX3.  Lots of strong signals,
 many in excess of S9+25.  A majority of the QSOs mentioned above were
 near strong signals and with the roofing filter in place I had pretty
 good luck ignoring the big guns while working weak signals.  I have to
 admit this is completely subjective, however years of experience with
 the K3 also tells me that the KX3 has similar characteristics in this
 regard.  The best example from on-air testing was the NM CW station I
 mentioned above.  His signal was marginal, meaning the APF was
 essential for pulling him out of the band noise.  At the same time, 3
 to 4 KHz up was one of those big guns thumping away.  I could even
 hear key clicks from the contester, but only a tiny amount of blocking
 from his signal on the KX3.  That's what I mean by similar to the
 K3.  It's not identical though.  I found instances where a little bit
 of a strong station's signal was near- or in-band, and as you would
 expect some pretty severe blocking occurred.  I'd recommend everyone
 make sure they have the roofing filter on the essentials list for
 purchase.  In many ways the roofer makes the KX3 what it was meant to
 be.

Re: [Elecraft] K3: CW in SSB mode broken?

  Terry, my understanding is that this feature is used almost exclusively
  by DXers on the VHF bands.  I have never seen it used on the HF bands
  even though it would be legal.  It allows you to keep the receiver on
  SSB while using the transmitter on CW.  I have used it on HF to touch
  up my amplifier tuning, but on HF there is no assurance that the other
  operator is CW capable or will know what to do.  Of course there is no
  such assurance on VHF either, but it more likely that the other
  operator has encountered the technique.   I would not attempt it in an
  HF SSB pileup.

Re: [Elecraft] [K3] Remote control protocol documentation

Bob,

That seems to confirm what I thought. Does anyone have any information on
this protocol? It would be great to get some specs even if they are
preliminary and/or incomplete - sure beats reverse engineering the thing,
especially since I only have one K3 :)

 From the changes notes for K3 firmware MCU 4.47 / DSP 2.73, 12-2-2011:

 REMOTE-RIG SUPPORT:

 One K3 can now directly control another, with one acting as nothing
 but a front panel. This remote rig mode provides a nearly perfect
 emulation of the remote K3's display and controls. (Previously, front
 panel emulation was limited by the K3's legacy command set.) The
 simplest way to use this is to connect the two K3s together using a
 null modem cable at the RS232 ports. However, by using a computer or
 a third-party hardware as an intermediary, it's possible to control a
 K3 over the internet or even a wiFi connection.

 Previously, front panel emulation was limited by the K3's legacy
 command set. hints at something new to make remote control more
 efficient. Wayne described it in this message posted on 21 Sep 2011:

 http://www.mail-archive.com/elecraft@mailman.qth.net/msg123387.html

 Virtually the entire K3 user interface is supported by the new remote-
 control protocol. It really feels like you're using the remote K3
 itself, including a 100% accurate emulation of the remote K3's LCD
 (flashing icons, etc.).

 Bob NW8L

 So the new REMOTE mode of the K3 uses the normal K3 commands from the
 Programmer's Reference to talk to the remote K3? I was sure I'd seen
 somewhere that a better protocol had been devised for this.
 
 Can anyone with such a setup verify if that's the case, possibly by
 snooping on the link?
 
 This is not directly related to RemoteRig, as far as I understand it will
 work by hooking up any 2 K3's with, for example, a null-modem cable or two
 serial ports on a PC virtually connected together.

Re: [Elecraft] KX3- laptops for I/Q

[Thomas Horsten]

Brian,

Some laptops are good, some are bad. This varies even between laptops even
with the same chipset, because the support chips differ. I've found that of
all the laptops I've tried, only a HP 8440 had a really good chipset for
SDR sampling up to 92kHz.

Consider getting an external USB soundcard like the E-MU 0202, which works
great on any laptop, or even the SDR Widget (still in the process of
building mine, but the performance data is amazing even at 192kHz, beating
any built-in or external sound cards on the market for this application!)

You probably won't get any decent 192kHz sampling in any laptop. To get the
noise level acceptable at this sampling rate, very careful design
considerations have to go into it, which would conflict with the space
constraints etc. of a laptop.

So far, I haven't seen a really bad HP, nor a really good Dell... But
those are just my experiences, YMMV.

Beagleboard acting as the backend to a GTK+ frontend emulating the user
interface on another machine in the network).

Does anyone know if this documentation exists, and if not, when it will be

documentation somewhere and I've missed it. If it's not out there, can
someone in the know provide me with a copy?

Don,

I was under the impression that a new protocol had been implemented in the
firmware, providing better performance and features for remote control
applications compared to the existing command set from the K3 Programmer's
Reference.

The approach of continuously polling all values and attempting to emulate
panel key presses by translating them into the corresponding commands is
not very efficient for this purpose, and it's not possible to achieve 100%
synchronization and correct mapping of keys to functions.

Re: [Elecraft] K3 won't PTT in data...

[Thomas Horsten]

Mike,

While in data mode, press Menu, dial to MIC SEL, ensure it's set to Line
In not RPL or FPL (right or front panel), now the mic should
definitely not be live and if it is (and triggers VOX), you have a problem
with your rig and it needs to be fixed before you use data modes again.

The selection is remembered separately for the DATA modes and SSB.

No matter how loud I scream into the microphone I cannot activate VOX
whilst in data mode. If the mic was live in data mode it would be
appalling, you'd be putting background noise splatter in the PSK31
passband, for example!

Re: [Elecraft] K3 spurious radiation?

[Thomas Horsten]

From the SoftRock Lite build
guidehttp://www.wb5rvz.com/sdr/sr_lite_ii/02_lo.htm -
I guess this could explain what we're seeing:


Sub-harmonic Sampling

Alan, G4ZFQ points out that on the 30m, 20m, 15m receivers, the Local
Oscillator produces a signal that is 4/3 times the desired center frequency
as opposed to the 4x the center frequency output for the lower band models.

Subharmonic works like this:- The LO outputs a 13.5MHz signl that goes to
the dividers /4, resulting in 1 3.375MHz square wave ( rich in odd
harmonics) being fed to the mixer. At the mixer, a strong 3rd harmonic is
present on the clock inputs, along with the fundamental of 3.375 MHz. The
3.375 fundamental multiplied by 3 yields the third harmonic of 10.125MHZ.
The Bandpass filter (BPF) performs the essential function of severely
attenuating any signals centered around the 3.375MHz fundamental frequency
and first harmonmic, but allows 30m signals centering around the third
harmonic of the 3.375MHz LO output. The result is that the mixer is dealing
with signals in the passband, centering on 10.125MHz, as though the
dividers were passing a fundamental frequency of 10.125 to the mixer. BPFs
are all that stop Softrocks from working on unwanted frequencies

Re: [Elecraft] K3 spurious radiation?

[Thomas Horsten]

Hi John,

I had this happen to me a few days ago where I was calling CQ on 7.015 and
was spotted on 14.0614 by Tim KQ8M's skimmer. I emailed KQ8M to ask him if
there was a problem with his skimmer. He replied that he wouldn't rule out
that the problem was in his Rx setup, but it was tuned to 20m.

Now I was running through the linear and an ATU, and I can't see any
logical relationship between the two frequencies, so I'm leaning to the
theory that his receiver was the culprit, although I did find it very
strange.

I think a lot of RBN skimmers use SoftRock receivers, and I'm guessing that
if his VFO was tuned to 14.050 using the 2nd harmonic of a 7.025
fundamental, it would kind of fit, but I'm still surprised that my 300W
signal to an inverted V was 6dB over the noise on the wrong band in Ohio,
3800 miles away on the other side of the Atlantic... I'm not sure exactly
because I don't know what receiver he was using, but it did have me puzzled
and when I saw John's post I thought I'd mention it.

Here's the spot in question:
