Re: [Elecraft] Proposed: more 6 meter CW beacons

[QRP Labs]

Frank, Dave, all

Jim AB3CV referred somewhat cryptically to my website
http://www.hanssummers.com yesterday in this thread. What he I think
*meant* to refer to was QRP Labs Ultimate3S "U3S" transmitter kit page
http://qrp-labs.com/ultimate3/u3s .

WSPR Lite does only WSPR and does not include a LPF. The U3S covers any
band from 2200m to 2m, with more power output and includes one LPF... or an
optional relay board can cover 6 bands and sequence through them. At $33 it
is also very much cheaper. The "U3S" also has a lot of other features, and
can send many other modes too, including CW, QRSS, JT4, JT9, JT76, Opera,
Pi4, Hellschreiber, ISCAT. So it is possible to do what Dave NK7Z
originally mentioned: a 6m beacon sending both CW and WSPR. The GPS
interface on the "U3S" means you can let it run autonomously indefinitely,
the GPS disciplines both the time and frequency.

I know this is not an advertising forum but several options have been
mentioned, including my personal website, and the U3S is a direct solution
to the 6m beacon that Wayne was proposing, and is already in use as such by
many people worldwide. So I hope it is Ok to mention it here.

Re: [Elecraft] K2 a little deaf?

[Don Wilhelm]

Lenny,

Are your IF filters aligned so a 550Hz signal is within the passband.
With the K2, simply setting STP for 550 Hz will not do it, you must do 
CAL FIL to make 550Hz appear well within the receive passband.


A properly tuned K2 will typically have a good response to a -140dBm 
signal from the HP8640B.


It is easier to take the K2 to the signal generator than to lug that 
heavy signal generator to the hamshack!

MDS measurement on my K2 and got some results I'm a little concerned about.


Yesterday I did an informal test. K2 set for cw, 1.5 KHz bandwidth, 
14.05 MHz, AGC on, preamp off. Attached siggen, tuned the K2 to 550 Hz 
tone and cranked down the siggen amplitude until the signal and noise 
were about equal, "by ear". Siggen output was -130 dBm. This was enough 
to cause me to look further.

Re: [Elecraft] K1 Band Boards

[David Gilbert]

Again, I'm not sure about this, but aren't all the boards the same 
except for the frequency determining parts (toroids and caps)?  If so, 
you could just swap out those parts on your 20/30 board.  Pretty sure 
the caps and cores would still be available somewhere, and somebody is 
bound to have the winding instructions for the toroids for 40 and 80.

I’ll see if someone is willing to part with a 2-band 40/80 board.

[Elecraft] [KX3] QSO of the week (and a re-learned QRP SSB tip)

[john]

Perhaps it depends on the type of operating you're doing. In a contest no
one cares how much power you are running they just want to copy your
callsign and report as quickly as possible. Sometimes "QRP" is the only
thing that is copiable and it becomes frustrating that the QSO cannot be
completed because the actual callsign was not sent enough times. The FCC
allows the self assigned /QRP indicator, I am not sure if it is allowed in
all countries.

Re: [Elecraft] K3 Display (Was K2 display)

[Bob McGraw K4TAX]

I suggest to one other to visit the local auto window tint place.   Get 
a scrap of light green window tint, cut it to size and put it on the 
plastic overlay for the display.    Or if you know someone in the 
performance theater circles, get a piece of light gel which they use on 
spots.   Easy to put on and easy to remove if you don't care for it.

In a similar, slightly humorous vein I wanted to replace some dial 
lamps on an old Yaesu with LED's. I had some white LED's and some 
sandpaper so set to work creating a degree of diffusion. Happy with 
the result I did a couple more and put them in the rig. The horror 
show started straight away. The 'white' LED's were in fact 
multi-colour of the seizure inducing kind, I guess they must call them 
rainbow LED's they change colour fast, then slow, then flash all 
colours in rapid succession. Quite the impression but not quite the 
right effect.

The K2 had backlighting since Day 1.  You could turn on/off the
backlighting by selecting the menu LCD Nite or Day.
For the K1, it was an option that was developed some time after the K1
was announced.

Re: [Elecraft] [KX3] QSO of the week (and a re-learned QRP SSB tip)

[Fred Jensen]

/QRP often, but not always, indicates a field operation, and they're 
sort of fun to work, at least for me. Having survived trying to move to 
AM in the mid 50's as a teenager and finding out the OT's did not like 
the invasion they said we were creating ["End of Ham Radio As We Know 
It"], I retreated to CW with a huge lesson in tolerance.  A FD CW op did 
send "Please copy," the Q was a struggle for him/ her, I asked for the 
name and I think I got Pat.  I went really slow, he/she said "QSL," I 
hope they enjoyed it.  I was QRP with my K2 and HOA-Stealth WOOF antenna 
[Wire On Organic Fence] since my K3 is in the shop. Learning is a slow, 
continuous process.

Re: [Elecraft] [KX3] QSO of the week (and a re-learned QRP SSB tip)

[Tony Estep]

Well, when I started working QRP I decided never to sign /qrp, but at least
once I wished that I had.

Martti, OH2BH, was on 20 phone and there was a gigantic pile. Finally he
started working by call areas, and when he came to the Zeroes, I finally
got my call through. So far, so good -- but he couldn't quite get my call
right. There were dozens of guys standing by, and Martti stuck with me over
and over, many many tries, until he finally got it. I was too stubborn to
explain that I was running 5 watts, but I could just feel all the guys
wondering why the weak guy was making everyone miserable. I guess that most
QRP ops have a similar story.

Re: [Elecraft] Filters

[Bob McGraw K4TAX]

Don't recall what band(s) you are working but.I find it amazing 
on the lower frequencies to add in 10 to 15 dB of attenuation and reduce 
the RF gain a bit provided marked improvement in the ability to pull 
weak signals out of the noise.


The idea advanced to me by others in the know is  legacy receivers such 
as the K3 and K3S provide better performance when the receiver noise 
floor is about ~10 dB below no signal band noise. If the no signal 
band noise is -97 dBm or about S-5, and accepting the fact the receiver 
noise floor is -135 dBm, since we can't change receiver noise floor we 
must change the signal level to the receiver.   By adding 15 dB of 
attenuation and reducing the RF gain by about ~10 dB, this should put 
one in the "sweet spot" for optimum receiver performance.


Works for me every time.  The proper filter adjustments and 
configuration also helps.

Re: [Elecraft] Proposed: more 6 meter CW beacons

Only if they are clean and don't give grief to neighbors, and I've heard 
some that fall into this category.

Re: [Elecraft] [KX3] QSO of the week (and a re-learned QRP SSB tip)

[Don Wilhelm]

Wayne and all,

I have found that signing "QRP" is more effective on SSB than it is on 
CW.  But it depends on the attitude of the listener at the other end. 
Some are encouraged by QRP, but others are turned off by it.

Gorgeous day here in Northern Cal, so off I went on a mountain bike trip 
to the bay, with the KX2 and a home-brew multi-band whip in my sling 
pack. I found a log to sit on, in the shade (a luxury at the beach), 
then deployed the station. Within a few seconds I heard K2K in New 
Hampshire calling CQ on 20 m SSB as part of the "13-Colonies” operating 
event. Called him with 10 watts, and since there were many stations 
calling, I added “QRP” at the end. Broke the pileup on one call. With a 
4-foot whip :)


“QRP” sounds quite distinctive on the air, often drawing the attention 
of good operators. Timing is key: if you have several stations calling, 
they’ll all try to get their call in at the same time, pretty quickly, 
leaving a nice gap right at the end where that magic word can drop in. 
Give it a try next time you’re operating with low power or compromise 
antennas.


I’m more of a CW guy, but this reminded me how much SSB can be when the 
bands are open. Also worked a number of VE stations as part of the 
concurrent RAC contest.


I took a photo of the rig, antenna, and a supporting 2-legged “bipod" 
that I’ll be happy to share if anyone is interested. Just contact me 
off-list.

Before we get carried away, there is a simple point involved. Different people 
use these various lists differently. I see nothing wrong with links. If you 
don’t like them, don’t click on them. Please don’t try to moderate if you’re

Thanks for the expaination.  I was thinking K3, and you were referring

[Elecraft] Elecraft CW Net Report

[kevinr]

Good Evening,

   Yes, the bands were more quiet and in both of the ways I had 
suspected they would be.  QSB was mild but present with an S2 variance 
at the greatest.  Twenty meters was more quiet so I was able to reach 
past the Mississippi and Tennessee Rivers.  However, spanning the Red 
River of the North seems problematic.  The signal from K4JPN was the 
weakest yet least noise covered of them all. Only a few words got 
jumbled due to QSB but the rest was plain as day at S1 or less.  It may 
be the 'Elecraft Effect' but maybe not; that is still in the hands of 
the research analysts.  All I can describe is what I see right in front 
of me.



  On 14050 kHz at 2200 z:

NO8V - John - MI

K0DTJ - Brian - CA

K6XK - Roy - IA

K4JPN - Steve - GA

W0CZ - Ken - ND


  On 7045.5 kHz at z:

K0DTJ - Brian - CA

K6PJV - Dale - CA

    To all you people in the sweltering heartland and eastward: stay 
cool, stay hydrated.


Until next week,

   73,

  Kevin.  KD5ONS

[Elecraft] QSO of the week (and a re-learned QRP SSB tip)

[Wayne Burdick]

Gorgeous day here in Northern Cal, so off I went on a mountain bike trip to the 
bay, with the KX2 and a home-brew multi-band whip in my sling pack. I found a 
log to sit on, in the shade (a luxury at the beach), then deployed the station. 
Within a few seconds I heard K2K in New Hampshire calling CQ on 20 m SSB as 
part of the "13-Colonies” operating event. Called him with 10 watts, and since 
there were many stations calling, I added “QRP” at the end. Broke the pileup on 
one call. With a 4-foot whip :)

“QRP” sounds quite distinctive on the air, often drawing the attention of good 
operators. Timing is key: if you have several stations calling, they’ll all try 
to get their call in at the same time, pretty quickly, leaving a nice gap right 
at the end where that magic word can drop in. Give it a try next time you’re 
operating with low power or compromise antennas.

I’m more of a CW guy, but this reminded me how much SSB can be when the bands 
are open. Also worked a number of VE stations as part of the concurrent RAC 
contest.

I took a photo of the rig, antenna, and a supporting 2-legged “bipod" that I’ll 
be happy to share if anyone is interested. Just contact me off-list.

Re: [Elecraft] K3 Display (Was K2 display)

[Martin Sole]

I think the solution to that particular problem is called the TS590. 
Unfortunately it comes with some other compromises.

That said, I think a green display on the K3 would be awesome.

In a similar, slightly humorous vein I wanted to replace some dial lamps 
on an old Yaesu with LED's. I had some white LED's and some sandpaper so 
set to work creating a degree of diffusion. Happy with the result I did 
a couple more and put them in the rig. The horror show started straight 
away. The 'white' LED's were in fact multi-colour of the seizure 
inducing kind, I guess they must call them rainbow LED's they change 
colour fast, then slow, then flash all colours in rapid succession. 
Quite the impression but not quite the right effect.


Martin, HS0ZED

The K2 had backlighting since Day 1.  You could turn on/off the
backlighting by selecting the menu LCD Nite or Day.
For the K1, it was an option that was developed some time after the K1
was announced.

Re: [Elecraft] 6M Beacons

[KC7QY]

W2JX,
Thanks for the reply.
Looks like the PDF paste was stripped off my post. Part 97.203(d) states 
unattended beacons are allowed on 50.060 to 50.080 MHz. Also states frequency 
limitations on other bands from 28MHz on up. 
This is in response to the earlier comment on people wanting to have beacons 
moved up into the 50.150MHz region. A bad idea in my opinion. Jim KC7QY

Re: [Elecraft] Proposed: more 6 meter CW beacons

[Martin]

Elecrafters,
from the point of view of a european 6m user, the main activity is in 
the range of 50.080 - 50.110 CW and 50.110 - 50.200 phone. If the band 
is REALLY crowded, it etxtends to - say- 50.300.
Nowadays there are digital modes above 50.250 or so including FT8 on 
50.313 .


Below 50.080, there are lots of cw-beacons all over EU , AF, AS.

I don't think one should establish an unattended station like a beacon 
in a range of 50.080 <> 50.400 . At least not in EU. It might get pretty 
loud.

Re: [Elecraft] KAT500 Antenna Memories

[dick]

Hi, Joel!

If you "train" the KAT500 with your resonant antennas, it should discover
and store the "bypassed" ATU setting.  Even though the MODE LED says "MAN",
the ATU settings stored are the "bypassed" settings.  You can see this in
the KAT500 Operate page - Try "ATU TUNE" for your resonant antenna. It
should discover that the best setting for this antenna is "bypassed". 

On some bands (my 20 meter beam), I end up with "bypassed" at the CW end of
the band, but up in the phone band the ATU provides a little help. But I
don't want to have to manually choose between BYP and MAN for different band
segments.  The ATU training session provides matching reactances when
needed, and ATU BYP when not needed. The ATU stays in mode MAN.

The same concept applies if you choose an antenna that never needs help.
Erase memories on that band/antenna combination, do an ATU TUNE at three
point s in the band, then you'll get that same setting in intermediate
frequencies.

You can choose with the "BYPASS SWR THRESHOLD" what SWR the ATU should use
when deciding whether to use "bypassed" or apply reactances.  Some really
want to see 1:1 when possible, others think that 1.2 is better bypassed than
with any real or perceived ATU losses.  

The ATU relay settings with the ATU BYP and when in mode MAN or AUTO and the
ATU discovers the "bypassed" setting in a tune are identical.  It's a real
bypass relay pair at either end of the ATU.

Each antenna wants to be the default on the bands shown, although Ant 3 can
be used on all bands, I can change manually if needed. 

I can cause the tuner to remember to change antennas as I change bands, but
it won't seem to remember whether to be in auto or bypass mode as the band

The K2 had backlighting since Day 1.  You could turn on/off the

For the K1, it was an option that was developed some time after the K1

Re: [Elecraft] KAT500 Antenna Memories

[Cady, Fred]

Hi Joel,

I think you probably need to go into the KAT500 Utility to the Antenna 
Configuration screen.  You can check and uncheck the antennas needed for each 
band.  I don't have my station set up at the moment but something like this 
might work:

Select Band 17 and 12, check Ant 1 and click apply

Select Band 20, 15, 10 and 6, check Ant 2 and click apply

Select Band 160, 80, 60, 40, and 30, check Ant 3 and click apply.


Tuner mode will be selected when you are on a band and you select the mode.

Note that you should train the tuner on 160, 80, 60, 40 and 30 and then run 
Manual mode, not auto mode.

Cheers,

Fred KE7X

In the past I've used the "Measuring Receiver Sensitivity" found in the

Re: [Elecraft] Any advice, please?

[Clay Autery]

THEN, read it a THIRD time with the device in your hands and go through 
every feature, knob, switch, and connector  Don't need to learn it 
ALL, but marrying what you read the first two times with the actual 
device will make things "stick" and make it easier to remember 1) what 
is IN the manual, and 2) speed your location of the information tidbit 
you need when the time comes to search.


I have a color printed copy of every manual published and keep them 
updated with all changes in nice neat, tabbed binders.
Have to confess though, that I am using the Elecraft PDF "encyclopedia" 
I compiled with Adobe Acrobat (a la ARRL pubs DVDs).  It has ALL 
pubs/manuals in it, and I can search it all at once, or per manual.

Re: [Elecraft] Any advice, please?

[Walter Underwood]

Yes, and if you are working phone, really follow the “Basic Voice Mode Setup” 
section. I tried to do it by twiddling knobs and got very confused. Elecraft 
transmitters work a bit differently than other amateur equipment. The audio 
drive and power output are independently controlled.

Also for voice modes, I’ve compiled some ideas from this list (along with one 
of my own) for cleaner mic bias and for TX EQ and compression setup.

[Elecraft] K2 a little deaf?

[w2bvh]

I dragged my HP8640B out of the "lab" (basement) to the second floor 
shack to do some antenna testing about a week ago. Before dragging this 
50 lb instrument back down two flights of stairs I decided to do a quick 
MDS measurement on my K2 and got some results I'm a little concerned about.


Yesterday I did an informal test. K2 set for cw, 1.5 KHz bandwidth, 
14.05 MHz, AGC on, preamp off. Attached siggen, tuned the K2 to 550 Hz 
tone and cranked down the siggen amplitude until the signal and noise 
were about equal, "by ear". Siggen output was -130 dBm. This was enough 
to cause me to look further.


Today I took some numbers. Same setup, but with a Fluke dvm instead of 
ears and the siggen phase locked . Started at -90 dBm drive and tuned 
the K2 to peak voltage reading. Then made the following measurements:


_Sigen (dBm)  Meter(V)_

-90          .38
-100                    .15
-110                    .050
-120                    .017
-130                    .011
(off)                     .010

Then did a rough voltage-ratio-to-dB "calibration" as follows: Set 
siggen to -100 dBm & measured the same .15V ob the K2, then ran the 
siggen output to 103 dBm and measured .204V. So 3dB signal difference is 
a voltage ratio of 1.36.


Finally measured MDS driving the K2 until the measured signal voltage 
was (.011 * 1.36 = .015 V).  I got this value at a drive level of -123 
dBm. Tried a second set of measurements with the preamp on using the 
same technique and got the same MDS of -123 dBm. Tried a third set of 
measurements with preamp off  and AGC off and got a slightly worse MDS 
of -121.


Now I know there are flaws with this measurement, especially in 
measuring a signal near the noise. But I know the provenance of the 
siggen, use it all the time and get good measurements from it. I trust 
it. If it was a matter of 2 or 3 dB I wouldn't be writing to the list, 
but this is 6-11 dB worse than the 2 numbers on Sherwoods site (-129 and 
-135).


FYI, another informal "measurement" I made was on  6M with the XV50. A 
signal was easily audible over the noise with the siggen set at -140 dBm 
drive!


On air results are equivocal: yesterday afternoon I couldn't hear my 
friend Joe N2CX 145 mi away who was qrp portable on 20M (something I've 
done multiple time in the past), but I had 3  consecutive easy q's to 
eastern EU last night on 30M...


On the K2, gain could be missing or noise could be high anywhere: front 
end, I.F, audio stages.


What do you think.  Could / should I send it away for work. It'd have to 
go somewhere with better instruments, since the K2 isn't exactly 
"broken". Or should I don't worry be happy?


73, --Lenny W2BVH

ps -FYI this is K2 1520, I built in 1999 & been in use here ever since.

[Elecraft] KX2/N1MM+ Macro

[K9MA]

I've gotten the new laptop to send CW with the KX2, but I'm baffled by 
the following:


For the K3, I have a CW function key macro:

F10 TU,TU *{LOG}

It sends the TU K9MA, then logs the contact.  This works fine. (I use it 
when I don't want to send the corrected call, usually because I sent it 
with the paddle before I typed it in.)


The corresponding KX2 macro I've tried is:

F10 TU, {CATA1ASC TU *;}{LOG}

This sends the CW, but does not log the contact.  Any suggestions?

Thanks,

Scott K9MA

Hello list,

I am reliably informed, by USPS, that a new KX3 has made it across the 
Atlantic to beautiful Wales, via New York and London. I hope to be opening 
the box soon.


Before I do, I thought I’d ask you guys if you have any advice for a 
newbiebefore I open the box,

Yes, download the manual from the Elecraft site  ..print it out 
and read it, cover to cover, and word for word, at least twice.    
It is amazing how much info is covered in the manual and available to 
all hams.

Re: [Elecraft] K2 display

[Fred Jensen]

OK, I may try paralleling R10 with something. I never operate at night 
with green electrons, here in the shack, while the K3 is in the Elecraft 
hospital, I'm on thoroughly brown electrons from NV Energy.  This may 
solve my seeing problem.

[Elecraft] OT: Call area "gotchas"

[Rose]

After decades as W5TKI beginning in 1951, a move to FL brought WA4HAA.
A Miami area 2M repeater was WB4HAA.  With the tropo ducting common in FL
much confusion resulted.
(In those days a 2x3 call was sure sign of a "newbie".)  Sigh ...

A current confusion factor is being a "zero" in the 7th call area.  Many
assume "MT" is really "MO", placing me in many contest logs as being in
MO.  It sometimes helps to send "de /7K0PP".

Trivia:  There are over 50 Kopp hams in  the US.  Inagine the stampede for
the call when I die!  (I'm now nearing 81.)

Re: [Elecraft] Proposed: more 6 meter CW beacons

[Dave Cole (NK7Z)]

Hi,
That's it!  Wouldn't that be nice to have a 6 meter beacon like that... 
It is so small that every year folks could break it out, put up a 
beacon, then loose it and buy a new one the next year!

Re: [Elecraft] Filters

[W2xj]

For most speech formants there is a gap above about 1000 hertz. If one is 
depending on only the F1 formant, then a cutoff of about 1000 hertz is 
appropriate. Another rule that applies is the 450,000 (or 500,000) rule. 
Multiply the highest frequency by the lowest frequency and the product should 
be one of those two numbers for a balanced response. So, if the upper cutoff is 
1 KHz, then the lowest would be 500 hertz. Such a response is slicing the F1 
formant which is typically 1 KHz wide.

Re: [Elecraft] Proposed: more 6 meter CW beacons

[Peter Torry via Elecraft]

May I raise a word of caution and suggest that you carefully consider 
the frequency of any beacon in view of the international use of the band.


 50.000-50.030 MHz reserved for a Synchronised Beacon Project 
*Region-1: *50.000-50.010; *Region-2: *50.010-50.020; *Region-3: 
*50.020-50.030


 General beacons have migrated to 50.4-50.5 MHz, to create more space 
for Telegraphy and the new Synchronised Beacon Project.


 Perhaps a word with regular users of the band may be a useful way forward.

This is the device you're referring to. It transmits 200 milliwatts 
on every WSPR segment in every ham band from 630 through 6 
meters. 200 milliwatts is amazingly effective when using two 
minute WSPR transmissions.

Re: [Elecraft] Proposed: more 6 meter CW beacons

[Wayne Burdick]

I heard from a couple of ops that the weak-signal community would prefer 
beacons be located higher in the band, say above 50.150.

According to published references I’ve seen, beacons reside from 50.060-50.090, 
and that is where I have found them (for many years). If this is a problem, 
someone should get the word out.

One reference in extensive use is the one from Nifty! manuals. See 6 m listings.

Re: [Elecraft] Proposed: more 6 meter CW beacons

[Dave Cole (NK7Z)]

I have a script that announces openings, based on scraping my DX Cluster.

If it sees DX stations spotting US stations from my CQ zone, it 
announces that band as open.  I am converting it to Grid square, as I 
want more resolution.  I will probably just look at the first two 
characters of the Grid Square, and trigger from that.


It is a Perl based script.  If anyone wants it, email me off line, you 
are welcome to it.

The K2 had backlighting since Day 1.  You could turn on/off the 
backlighting by selecting the menu LCD Nite or Day.
For the K1, it was an option that was developed some time after the K1

Re: [Elecraft] Proposed: more 6 meter CW beacons

[Charlie T]

I know it's no longer a requirement, and I especially can't argue the point, 
BUT, I would ask that any proposed 6M beacon use a call sign appropriate for 
the location of the beacon.
Yeah I know, the grid square should be sufficient, but years ago, there was a 
6M beacon in the Washington DC area signing a KL7 call. This was before the 
proliferation of out-of-area call signs were common.  Talk about shaking up the 
troops when THAT one hit the airwaves!

And yes, when I moved to Virginia I held a secondary location call,  WA4LJQ 
(could it get much longer for CW?), with k3ICH still assigned to my parents 
house in Forestville MD where I was 1st licensed as KN3ICH.
I was very lucky to have been able to hang onto my original call, as many 
didn't have the luxury and had to loose their old calls when they applied for 
the new station location.

Re: [Elecraft] Filters

[Don Wilhelm]

Clay,

We are not talking about shifting the pitch of the signal by 50 Hz, we 
are talking about enlarging or restricting the pitch at only the low 
frequency end or the high frequency end by 50 Hz.
The LowCut and HiCut controls are like the Bass and Treble controls on a 
car AM/FM radio.  Think what would happen if your radio's Bass control 
were reduced by 100 Hz instead of 50 Hz - the difference is insignificant.


Oh yes, the Bass and treble controls on that  AM/FM radio are not 
calibrated for precise frequencies like the K3 HiCut/LoCut controls are, 
so we "use our ears" to determine what is best.  We should do the same 
for the K3/K3S/KX3/KX2.


There is no communications effectiveness for frequencies below 300 or 
400 Hz (0.30 to 0.40) on the low cut side, and there is little voice 
recognition in that range.  The effective range for voice recognition 
begins at about 500 Hz, and extends to about 2600 Hz.  That is for 
recognizing the characteristics of a particular voice pattern we are 
familiar with.  For communications effectiveness, we can reduce the 
listening range to 500 Hz to 1700 Hz and still communicate with clarity.

[Elecraft] Proposed: more 6 meter CW beacons

[Wayne Burdick]

When 6 meters opens up, a few low-power CW beacons I’ve never heard always pop 
up in the low end of the band. We could use a lot more of these during 
sporadic-E seasons. If you have a 6-meter-capable QRP rig gathering dust and an 
antenna to put it on, you might consider joining in. In addition to giving us a 
few more data points on propagation, it’s a novel way of promoting CW use.

Just as another observation...  My Low Cut on SSB in Norm I is set to 
0.015 by default.  I can dial it UP by 0.1, 0.25, 0.35, etc.
OR, if I dial it down to 0.05 as long as the starting point is above 
0.05.   Cannot dial in 0.05 from 0.00.

Yup, you are right. The manual clearly states that PB CTRL only affects CW and

It appears to be fixed at .1 KHz for SSB for both low and hi cut. Those 
increments work pretty well as is.

I apologize. I’ve dumped the digest, so it won’t happen again.

I was hoping we could poke around and maybe find new, old stock parts that 
might meet the specs for the 4-band board. If that doesn’t pan out, I think 
I’ll see if someone is willing to part with a 2-band 40/80 board.

Re: [Elecraft] Filters

[Don Wilhelm]

On SSB a change of 50Hz bandwidth is usually insignificant.
Those who are blessed with perfect pitch may differ when listening to a 
single tone, but for communications effectiveness, I just don't see the 
point.

Temporarily switch to Shift/Width and set Shift to a value that,
when divided by two results in a value of X.X5.  Now switch back
to Hi/Lo ... those value will end in X.X5 and step in increments
of X.10.

Re: [Elecraft] K1 Band Boards

[Don Wilhelm]

Randall,

Wayne was referring to the 4 band board which had 16 wide range trimmers 
with a low temperature coefficient.
The 2 band board does not have that limitation.  All the capacitors are 
fixed and the ones in the frequency determining circuits are C0G or NP0 
types.


Please do us all a favor when you post from the digest - strip away 
everything except the post you are referencing.  Your post sent all of 
us the entire digest.

[Elecraft] KAT500 "Last Observed" "Tune State"

[Michael Blake]

What do the numbers displayed after the Tune State mean?  The right hand three 
digits seem to be the tuned SWR but I can not decode the other digits.

For example only,  my last Tune State numbers for a 3.710 mHz solution are 0 6 
76 1.14

The tuned VSWR was 1.14, the Capacitance was 180pF and the Inductance was 
2100nH and the Caps are on the antenna side.

Re: [Elecraft] Filters

One question: On my K3S I cannot set the LO CUT to .35KHz it only 
steps in .10 increments not 0.05 increments is there some CONFIG

item I need to change?

Temporarily switch to Shift/Width and set Shift to a value that,
when divided by two results in a value of X.X5.  Now switch back
to Hi/Lo ... those value will end in X.X5 and step in increments
of X.10.

looked through the CONFIG menus and Fred Cady’s book however I did not see

Congratulations. The K3 is a really nice radio with extraordinary factory 
support.

For SSB, I set low cut to .35 KHz and adjust the upper cut between 1.9 KHz and 
2.8 KHz, depending on conditions. Higher makes for easier copy, but lower will 
eliminate more noise, and help with nearby stations. Remember, the crystal 
filters are to protect the AtoD converter in the receiver. The DSP has many 
useful settings between those of the installed filters.

I recently purchased a K3 and trying to set up for SSB.I do not do code.
Is there any recommended settings for the shift lo cut and width?
It has the KFL3A-400 and the KFL3A-12.8 8 pole filters installed
I have read the manual and it does not really help me.
