Re: [Elecraft] Shipping status update

   I was wondering the same thing. I keep looking for the update, but it's 
not there. C'mon Eric, don't keep us in suspense so long.


   Laurent, I ordered my K3 on Oct 13.

[Elecraft] SHIPPING STATUS UPDATE

[srife]

   I know there are over 600 happy K3 owners out there now. So would it be 
asking too much for a shipping status update that we were supposed to see 2 
days ago? The remaining few of us would also like to have an idea when our 
order might ship.

   We certainly don't hear the uproar about the late updates that we did 
just a couple of months ago. So that tells me that there are either less 
people waiting for K3s, or that the Europeans have all gotten their K3s.


   Maybe if I stir the pot and make enough noise, we will get some

Re: [Elecraft] SHIPPING STATUS UPDATE

[srife]

   Story of my life Don...just above the noise.  :-)

   The update was due this past Tuesday. That's when the last one ran out, 
date wise. I ordered Oct. 13. I figure I'll get mine sometime in April. But 
I, like others in the recent past, would like to see those updates on a 
regular basis as the dates get closer to me. Five months ago I could have 
cared less and resided myself to the fact that I would get a K3 some day. 
Now I am getting ants in my pants.

Stan - it would take them longer at this point in the
K3 delivery cycle than it's worth to update more than
every 2 weeks and they've been fairly good about that.


At any rate, when did you order?

Maintaining their present breakneck rate, March will
ship orders placed in August and September, April will
ship orders placed in October and November, and May
should get December and January if the trends
continue. I'm not sure how May will be affected by
Dayton (biq squeaker there).

I'd venture to say that in the rankings of SQUEAK at
elecraft, your signal was just above the noise. My
guess. ;-)

Re: [Elecraft] SHIPPING STATUS UPDATE

   Larry, we may be in the next update, but if my luck holds out it will be 
the one after that. So I figure: 2 weeks per update = 4 weeks...then two 
weeks notice for the shipping and one week for the ACTUAL shipping. So MINE 
could be 5 weeks away, or more likely 7 weeks. But I am hoping for 5 (maybe 
less?).

Re: [Elecraft] K3 Board Flex

   Probably not harmful, but it just seems that it would not look first 
rate in a first rate rig. How much of a pain could it be to have a fix for 
this by providing something as simple as what Doug has done. Maybe in future 
boards there could be a hole placed in the FP board to match the one in the 
frame, and a non-conducting standoff and a couple of screws could be added 
to the kit. Would that be such a big deal? For the rest of us, a mod kit in 
K2 fashion.

   I ordered my K3 on October 13th with the 50% deposit , but a month or so

If you have a DMM with a diode check feature, just probe the LED terminals.
When you have the positive lead on the anode the DMM will indicate a forward
biased diode junction and the LED will light up!

It won't work with modern DMMs in ohms scale because they limit the
current too much to avoid damaging parts, but diode check works FB.

Windy, as I recall, the gap between the headphone jack washer and front
panel was about 0.017.  If you just want to close the gap and get rid of
the rattle, you might try what I did: a trim washer from a spare 1/4 jack
was 0.018 and added just the right amount of spacer to eliminate the 
rattle

and fit the front panel w/o any discernible flex +/-.

Re: [Elecraft] K3 Rev C +AF filter

[srife]

Sorry, my posts have been going to individuals instead of the reflector.




I have tinnitus in both ears and less high frequency noise is a good
thing for me. I can see where the younger guys, and some older ones that
still have good hearing, are not bothered by the K3 audio. The Heil headset
does seem to make an improvement...or maybe it's just that all of the other
noises (room etc.) go away and it makes listening to the K3 much better
because you can turn down the AF gain some. 

I'll have to admit that I have not attempted adjustment to the
equalizers or messed with the AGC adjustments that some have mentioned. I am
in the process of getting SN/0690 up-to-date with the mods that are listed
on Elecrafts site, and also have ordered the upgraded DSP board. Once the
hardware  FW are up to date I'll start digging in the new manual and see if
I can make my listening experience better.

This is a good thread and I'm listening.

I have two K3s, one has  the new DSP board, so I hooked them up together and

listened to low frequency tones. The higher SN radio definitely has more 
bass. In fact I have noted a few times, just how low it goes. It seemed very

unusual for a communications radio to do that. So I listened to the older 
one and it has less bass, but to be honest, I don't see a problem with it. 
It sounds just fine to me. Now if it was my stereo FM receiver I would heave

it out, but I chase DX with it and see no big reason to update it. I guess 
it is a personal decision for folks. I am using a Heil headset to make the 
comparison. I am almost 65 years old and my hearing is hosed on the high 
end. I am not sure if it is from the several decades of weak signal work, or

having way too much fun in the 60's, but my upper limit is now a bit over 6 
or 8 kHz. I tune in CW at about 450-500 Hz.

 All the board changes do is improve low end response, which in my opinion

 The 'filter' mentioned is not a peak or null filter, but just a lowpass 
 filter to remove
 some very high-pitched DSP artifacts that bother some operators.

 In my opinion, this replacement board is not something that everyone

 probably order the filter sub-board by itself when it becomes available 
 even though I'm
 probably too old to hear the DSP artifacts in question, but don't intend 
 to bother with
 replacing the DSP board.

website, the description of the upgraded DSP REV C board describes exactly
what changes it has. Someone actually posted it here on the reflector
earlier for all to read. It is pretty clear to me, but YES, the low
frequency response mod has been added which means that it does have a low
frequency bandpass filter for the audio chain on the DSP board. At least
that is what I interpreted it to say. 

I hope I haven't mis-spoken.

Re: [Elecraft] Noisy K3 receiver

[srife]

You guys may be exceptions to the rule. The # of complaints seem to
far outweigh what you two guys are saying. I'm not saying you are wrong,
just that it seems that a lot of people are hearing a problem. I have
SN/0690 and to my ears it has always been on the noisy side. Some of this
may be due to ignorance about how to set up the K3 properly. I am pretty
sure that is true on my end, in part. I have never tried to dig deep enough
in the manual or the menus to try and make the situation any better. It is a
little intimidating to me and that is why I have never dug too deep in to
the menus to try and make things better.

 I hope to change all this in the near future. I am catching up on
the mods and upgrades and with an updated manual I hope to have some success
in making my K3 sound better to MY ears. 

Ed, I most definitely have never felt like that my K3 was TOO quiet.
Lots of background static and hash that is fatiguing to listen to. I don't
know what else to say...I know I am not imagining it. I would much wrather
listen to my TS-830s, but I have hung in there with the K3 knowing that
there is light at the end of the tunnel. I just have to figure out what page
that is on in the manual.  hi hi

 I've had #1823 for just over a year, and I still don't like
 the sound of the receiver. That's the reason the K3 sat in a
 box for months while my trusty FT-1000mkV sat on the
 operating desk (until the MkV went on strike in the middle of
 the SS CW :-(

 I've read all the posts in this thread and have to say ... I just don't 
 get
 it.  What noise?!  If anything my two K3s are too quiet!  It has occurred
 to me more than once that I might have an antenna disconnected or perhaps
 blew out the front-end to the radio.  The most distinguishing 
 characteristic
 of the K3 (for me) is how quiet it is when you slip on the headphones. 
 The
 K3 is distinctively quiet compared all the Icom, Yaesu and Kenwood radios 
 I
 own or have operated.  I now realize that all the pre-K3 radios I've used
 were somehow amplifying or emphasizing the band noise, plus adding a bunch
 of digital artifacts, in the audio.  I am completely stunned by the posts
 here that report noisy K3 receiver and escaping to a quieter Japanese
 radio.

 I've been using K3s 11 and 17 ever since the field test units first came
 out.  I've kept current with all the updates and mods so despite the early
 serial numbers, these radios are equivalent to what is currently shipping.
 I always have the latest field test firmware in both radios.  This is
 pre-Beta and pre-production firmware that has never interfered with my use
 of the radio.  I use the radios primarily for CW, RTTY and (rarely) SSB
 contesting, plus a bit of DXing.  It took me a full month of using the K3 
 to
 finally accept the fact that its receiver is so incredibly quiet compared 
 to
 any other radio.  I thought something was wrong!  And yet with the greatly
 reduced band noise in the headphones, extremely weak signal are easy to
 copy.  80 and 160 are like new bands, more like the higher bands, with my
 K3s.  And the pile-up/crowded band receive capability is far superior to 
 any
 radio I've ever operated.

 I'm not doubting the reports here on the reflector about noisy K3
 receiver, but I have to say that either the specific radio has a major
 defect or the various gain and AGC controls are not setup correctly.  W4ZV
 has posted on this reflector several excellent explanations on how to
 properly adjust the K3, or any radio for that matter.  I would love to 
 hear
 one of these noisy K3 receivers and see how they are configured.

I find no actual description of what the K3DSPUPGD (REV C) consists
of. Does it include the lowpass audio filter that everyone keeps talking

Could someone from Elecraft please straighten me out on this so I

DSP upgrade board? All this talk on the subject has got me confused.

Re: [Elecraft] KRX3 roofing filter matching for diversity receive

[srife]

H...   Ed, I almost tried using the built in
translator in Outlook...but then I recognized some of those words, like
is and the.  :-()  It almost let the smoke out of my head.

Seriously though, I don't understand the filter setup
technicalities. I can get through setting them up per the defaults in the
manual, but I would like to understand more about what you said. I'm not
sure why a filter would be advertised as a 250hz filter but actually have a
(usable?) bandwidth of 370hz. Is this just a difference in how it's
measured?

I have SN/0690 and am just now installing the KRX3. It arrived a few
months after the radio, back in mid to late 08, and I just never got around
to installing it. I have identical filters in both the main and sub receiver
(13khz, 6khz, 2.8  400 respecitively, with # 5 empty) so I can try out
diversity receive. I don't do much CW so didn't figure I needed a 250hz.

I'm sure I'll be asking some questions about this in short order,
once I get the rig back together. I am doing some of the mods and am
currently waiting on some parts and the REV C or D (or whatever it's up to
now) DSP board.

Roofing filters are selected by either of two ways.  One is by directly
selecting FLx on the K3 front panel.  The other is by changing the DSP
bandwidth via WIDTH, LO CUT or HIGH CUT.  When the DSP bandwidth is
decreased to the crystal filter bandwidth, then that roofer is selected.
(Or, when the DSP increases beyond the current roofer's bandwidth, then the
next wider roofer is selected.)

It is important to note that the roofer bandwidth is specified by the user
in the K3 CONFIG menu, and you are not constrained to use either the
marketing bandwidth or the actual bandwidth of the filter.  You can put in
any bandwidth you want because all you are doing is telling the K3 what DSP
bandwidth to engage that particular crystal filter.

Most users specify the marketing bandwidth of the filter, e.g., 250 Hz for
the 250 Hz 8-pole filter.  So, as you decrease the DSP bandwidth and reach
250 Hz, that crystal filter will engage.  (Or, if you select FLx, then
crystal filter 'x' is selected and the DSP bandwidth is set to 250 Hz.)  But
you can specify 350 Hz, which is actually rational since the real bandwidth
of this filter is 370 Hz.  Some people even specify a wider DSP bandwidth
engagement point such as 400 or 450 Hz, because they want their crystal
filter bandwidth INSIDE the DSP bandwidth.

So, think about the relationship of the two filters (crystal and DSP), the
resultant cascade bandwidth of the two, the shape factor of the two filters,
and the passband shape.  Decide the DSP bandwidth at which you want your
particular crystal filters to engage.  There are arguments for keeping the
roofer wider than the DSP at all times and vice versa.  Remember that when
the DSP bandwidth is near the roofer's actual bandwidth, the cascade
bandwidth will be significantly less.  When one is much narrower than the
other then the narrow bandwidth dominates the IF bandwidth, but other RX
characteristics like IMD performance will be determined by the roofer
bandwidth.

Setting the DSP engagement bandwidths for your crystal filters affects both
the resultant IF passband width, shape and sound of the audio, as well as
the RX performance characteristics such as IMD.  If your head hurts thinking
about all this, just specify the bandwidth number in the part number of the
filter!  That is a good default and the radio will work great.

Re: [Elecraft] KRX3 roofing filter matching for diversity receive

So is the information in the manual just the easy way to set it up,

From reading the manual I understood that they had to be in decending order
starting from FL1, and the filters in both receivers had to match for
diversity receive.

Bill, it's simpler than what you're looking for.  You can put your
widest filter in FL1 and install them from there in descending
bandwidth.  Use the K3 utility to set up the filters, much easier than
doing it with the config menu.  The radio automatically switches in
the matching filter that matches WIDTH going down.  This will be done
separately in each RX regardless of what filter slots were used. You
do not have to make slot assignments identical.

 Hi folks,





 I’m trying to configure the K3 receiver for diversity receive.    I’m
populating the roofing filter slots in both receivers with matched filters,
and the question came up:   When the K3 automatically selects the correct
roofing filter to match DSP filter bandwidth, does the K3 do this by filter
  bandwidth, or by FLx number?

   In other words; when I use the “width” control, and decrease DSP
bandwidth from 3.0 Khz to 2.0 Khz on the front panel,   the K3 switches from
the 2.8 Khz roofing filter located in FL3 to the 2.1 Khz roofing filter
located in FL4.   With the sub-receiver on, and in diversity receive, does
the K3 switch the sub-receiver roofing filter from FL3 to FL4, like the
main, or is it smart enough to know that my sub-receiver has it’s 2.8, and
2.1 Khz roofing filters in FL1 and FL2 respectively?    Does the K3 select
the correct roofing filter by bandwidth, or by FLx number? Is the selection
logic the same for main and sub-receiver?





 The KRX3 manual is a little foggy on this.   It says you have to have at
least one roofing filter, and if that happens to be the KFL3B FM filter, it
MUST be in the FL1 location.   It also says that you must have the widest
bandwidth nearest FL1, but does not say it must be located at FL1.

Yes, a well known issue for a LONG time...with a SUPER EASY solution.

It is indeed due to the internal speaker.

A year or so ago, I got a call from a local (a couple miles away) that
he had a spurious on his K3 (I helped him build it).  I listened,
yes it was there.  When he switched from the internal speaker to
headphones, it was gone.  I think he ended up using an external
speaker which also solved the problem (some guys like speakers!).

Re: [Elecraft] Raised K3DSPUPGD price?

[srife]

Not a shortfall on Elecrafts end. They designed it that way.
Consumers have driven some of the changes that have been made, like this
one. If Elecraft gets enough feedback on a certain item, then they redesign
to address the wants and needs of the consumer. You certainly can't get that
kind of response from YaeKenCom or ComYaeWood or Fucumyung or whatever.

If you don't like the price, then don't buy it. Personally, I feel
like it's a bargain considering what I have invested in the radio. As they
continue to come out with mods that will improve my K3, then I'll continue
to buy them, or in the matter of the FREE mods I'll continue to request
them.

The K3DSPUPGD was expensive at the old price, bearing in mind the cost of
carriage and return.  Now the price is verging on the obscene.  For the
money you'll get a Rev B board with a few component changes and the added
LPF board.

For those who can use a soldering iron, the W9AC bass enhancement mods work
perfectly well, so keep fingers crossed that the LPF, when it appears, is
priced fairly.  

Is it right that we're being asked to pay through the nose for things that

Hi all,

As you probably know, we keep a list of firmware features and  
improvements to be added as time permits. Many of the most-requested  
changes were made over the past several months, keeping pace with the  
demands of the fall/winter contest season. (A few that come to mind:  
switch sequence automation via macros, improved DVR interaction with  
PTT, main/sub audio mixing, improved NR, lockable transmit controls,  
and many enhanced remote-control commands.)

As we head into 2010, we'd like to refresh the master firmware list  
based on your input. Items already on the list have priority, of  
course, but this is a great opportunity to let us know what else is  
missing or could be improved. Our goal is to make the K3 as easy to  
use as possible, while providing the advanced features you need for  
specific operating situations.

We're also planning a renewed effort to assist application software  
developers. If your ideas for improvements involve changes to both K3  
firmware and a favorite application, we'll pass it along to the  
developers and work with them closely.

We're making great progress on the P3 Panadapter and other new  
products. There will be some surprises in 2010 :)

Re: [Elecraft] securing K2 RF board

[srife]

I used the Panavise circuit board holder (large) even after
installing the 2D connectors. Just adjust it for a light hold and it will
stay in the vise ok. Even some of the components mounted REALLY close to the
edge of the board had the same affect as the 2D connectors, as far as using
the Panavise. Just have to adjust the clamping action to hold it lightly but
securely. The springs in the jaws will allow the jaws to hold on to the
board out at the end of the jaw, while touching the 2D connectors at the
other end.

Don I don't know how you did it without some kind of a vise. But I
guess everybody has their own technique. Personally I like all the
conveniences and gadgets that are available for this kind of work. 

The K2 was my first major assembly project. I had never done
anything nearly that complex before. Not bragging but everything checked out
ok the first time everytime, and I did it in about 6 days if I remember
correctly. Of course that was 12 or so hours a day not counting the breaks
that I had to take. I had a weeks vacation scheduled just for building the
K2. That's probably not a major feat for some of the guys that built K2s,
but it was a personal first and best for me as a rank beginner.

Conway,

Just my way of working, I HATE things like the Panavise, it is more of 
an encumbrance than a help IMHO.
However, you may elect to delay mounting the 2D connectors until you 
need to mount the side panels - that will allow you to use your Panavise 
if that is your preference.

With or without the 2D connectors, do not use the panavise until after 
you have mounted the relays - use the procedure in the manual to hold 
the relays in place with a book  (or board or other hard surface) to 
allow you to flip the board over with the relays in place prior to 
soldering.

Re: [Elecraft] K3: LPF, bass audio, new DSP board: Stirring the pot?

[srife]

I had already paid for mine before they decided to add the LPF in to
the deal, so I suspect you are correct Julian. Don't know if they initially
were going to offer the LPF as a customer DIY add on, or if they decided it
might be better if they did the work in house to eleviate too many failures.

It was probably easier for them all around taking the option they
did.

 I'm not too thrilled about the unannounced price increase from 69 to 89

I suspect that the price increase reflected the addition of the LPF board,
and the short window of opportunity for purchasing the DSP+LPF at the old
price was the time it took for Elecraft to realise they would be losing
money on the deal. The $69 was really just for the Rev. C board swap without
the LPF. I don't know if anyone actually got one of those, or whether
Elecraft delayed fulfilling the orders until the LPF was ready and decided
not to ask those who had already paid fro an extra $20.

Re: [Elecraft] K3: LPF, bass audio, new DSP board: Stirring the pot?

[srife]

I can't figure out why they are charging 5 bucks for 2 resistors in
the K3 I/O OUTPUT BUFFER KIT, when they are giving away the parts for the
rest of the upgrades for just the price of the postage. Are these two
resistors gold plated or something? I just used a spare 15K 5% leaded
resistor I had in my parts box. 

Shouldn't that be a give away too Eric?

Well, I ended up ordering the DSP upgrade board today, plus a few other
items.  Everything came to a little under 200 dollars including shipping.
Here's what I ordered:

BNC-MM  $6.95   1 Male-Male BNC
K3DSPUPGD   $89.95  1 K3 DSP Upgr. Swap
K3IOBUFFKT  $5.00   1 K3 I/O Output Buffer Kit
XG2 $79.95  1 3 Band 1-uV and 50-uV Rcv. Te

I figured the XG2 would be a good thing to have around as well.  I can
finally get around to properly calibrating my s-meter.
Slightly OT question though; you know the 1 wire mod that's used to protect
the front end?  Where can I buy the type of wire required?  I think it's
Kynar... whatever it is, its insulated, solid-conductor wire that's around
22 guage.  When I performed this mod several months ago, I had a few of
those small, pre-cut and pre-tinned solid conductor wires included in
breadboard electronic kits, and I used one that was the right length.  I
like to buy a spool of this stuff though for a few more breadboard projects
I'm working on.

Re: [Elecraft] K3 Sub Rx antenna input choices

I'm thinking of a relay at that point to switch between them. But
then I guess there goes your isolation afforded by the BNC.
Would a Y cable affect the input Z enough to affect the gain?

Subject: [Elecraft] K3 Sub Rx antenna input choices

I purchased my sub-receiver for one specific use ... to monitor
6M for band openings while the radio might tuned to another 
band.  I used the Elecraft-supplied BNC(F) to TMP(M) cable 
to feed the sub-receiver's input.  This arrangement is essentially
permanent unless one does a partial dis-assembly to gain
access the sub-receiver's input jack.

I later decided that I'd like more flexibility regarding the choice
of antenna for the sub-receiver.  I now route the cable from the
BNC(F) to the area atop the sub-receiver and secure it to the
knurled nut on the top of the sub-receiver.  I also routed the
cable from the antenna tuner to the same area and secured 
it along with the end of the cable from the rear panel BNC(F).

Next I made up a short (6) TMP(M) to TMP(F) cable that 
plugs -permanently- into the sub-receiver's input.  This short
cable is also routed to the same area as the ends of the other 
two cables.  Now, by lifting the top cover of the rig, I can choose 
which source is fed to the sub-receiver's input via the short
extension cable.

It's -much- easier to gain access to the sub-receiver's antenna
jack if the KI03 is removed.  It's easy to damage the input jack 
on the sub-receiver if you try to plug a cable into the jack from 
above.

Re: [Elecraft] [K2] how much harder to build: K2 vs K1?

[srife]

Hi LS. I have never built a K1, but I would guess that a K2 is 2 or
3 times the complexity of a K1. But don't let that scare you. The
instructions for assembly are superb and the Elecraft support is as well.
The K2 was my first major project and I just followed the assembly manual to
the T and everything worked as specified. You will have some questions
along the way, but Don Wilhelm and a host of others here on the reflector
will help you out.

Ordering the torroids pre-wound will will speed up the proces quite
a bit and is not all that expensive.

Subject: [Elecraft] [K2] how much harder to build: K2 vs K1?


Hi all,

I'm considering building a K2, but here's my situation. I'd be a first-time
kit builder, I've never had the opportunity to build and the K2 looks like
it'd be great fun and a great learning experience. The K1 sounds like it's
the better choice for a first-time build, but the K2 matches what I need in
a radio a lot better.

So I guess my general question is, how much harder would a K2 be to build
over a K1? I.e. what are the gotchas with the K2 for a novice builder that
aren't in a K1?

I know this is kind of vague, but that's the only way I can think of to ask
the question. I think I'd still do OK if I took my time and got good tools
(I just ordered the recommended weller soldering station).

Thanks,
LS

[Elecraft] [K3] KRX3 install

I've just finished installing a KRX3 with the KBPF3 and when I push
the sub button it tells me NO SUB. I have been through the menus several
times, setting up the filters and modes and bandwidths for the main and the
sub receiver but I still get the same error when I try to select the sub

doesn't ask me about setting up the KBPF3 for the sub. I assumed you would
have to tell it when to use the KBPF3 as with the other filters. Maybe this
is done automatically when going outside the amateur bands. I seem to recall
something about this. 

I'm sure I have missed something. Can someone help? This is the very

Re: [Elecraft] [K3] KRX3 install

I've sent a bunch of replies and they all went to the individuals 
instead of going to the reflector. Sorry about that folks.

Yes, the power cycle did fix part of my problem. I could then see the 
SUB come on. I also encountered an
ERR PL2 error code. I had to go in and re-calibrate the VCO for the sub 
receiver. I had somehow messed that up.  Whenever I pressed the ATU TUNE button 
I would get an ERR TXF error. Looked that up and figured out that I was 
transmitting  on the wrong bandwidth for CW. There is an awful lot to do when 
setting up 10 filters for the K3 and the SUB receiver. I finally got it all 
correct I think, but I still had no audio for the SUB receiver. After reading 
the instructions I realized that I had to set the number of speakers to ONE, 
and then I had audio as well as receive signal from the SUB receiver. I need to 
get some stereo speakers.

I have more reading to do.

Thank you all for your help,

And you can hit SUB while in the KBPF3 feature menu to turn on which RX

I don't think you'll hear much of anything on a K2 at 8.215 MHz.  
That's well outside the 40m passband.  The K2 does not have general  
coverage RX.

Stan,

The K2 cannot receive that frequency - the dial may say so, but the 
VFO/PLL has maxed out at about 7400 kHz (if you are tuning from 40 
meters) and although the dial continues to increment, the actual 
frequency will not go any higher.  Even if it did, the bandpass filters 
would probably attenuate the signal significantly.  For the same reasons 
I doubt that you can tune downward from 30 meters and get that low.
You will have to use a general coverage receiver.

If you have an oscilloscope you can connect it and see the output. I have a
K3 which has the modified IF with higher output. I have a 5 MHz (-3 dB)
oscilloscope in my shack for monitoring. Even at 8.215 MHz it indicates up
to +/- 50 mV in the 40 m band (no ATT, no PRE). In other bands it is lower,
like about +/- 5mV (no ATT, no PRE) in the 80 m band. Due to the bandwidth
limitation of my oscilloscope, I guess these values should be doubled or so
to find the true values.

Re: [Elecraft] [K3] IF output

[srife]

I was expecting to hear a carrier, but after I thought about it that
can't be the case. 

With the IF connected to the Subreceiver I can tune around either
side of 8215 and hear QSO's. I have to have the Preamp on by I can hear
them. Would that be considered adequate? I have done the IF mod and used a
15K resistor in place of the original. I actually had a 10K  a 15K and Gary
Surrency said either one of them would work. So error on the side of caution
I used the 15K.

and even less depending on which store you will buy it at,its freq response
is from 100 to 18,000Hz on TX and 20 to 20,000Hz on RX,having the K3 EQ you
can equalize it to have either sweet ragchew audio or high punch
dx/contesting audio,the headphones are big enough to cover your whole ear

have to reduce the mic gain at least half,go for it,its a keeper.

After this past week ends NAQP contest and receiving several notices
about distorted audio on my K3/10 using a Telex MRB2400 aviation
headset. It might be time to up grade my head set to either one of the
above. Frankly the Telex becomes rather heavy after about 6 hours.
Since I operate pretty much equally between contesting and general DX
chasing and/or QSO I need a good all around headset. I would like to
hear from someone who has operated with all of them.

[Elecraft] K3BSR

[srife]

I installed and was trying to setup Don's program. Got it going and
it seems to work ok but there seems to be an issue with the receiver audio
going deaf while tuning rapidly with the VFO.

My question is, this is the day after and I have turned on the K3
and A  B VFOs are on the same frequency and are tuning together with the
right most decimal point in the B VFO flashing. How do I get it out of this
mode? I've tried split but it doesn't seem to be in split mode. The VFOs are
locked together somehow. I can tune the B VFO independantly but the main
dial tunes both.

Any quick answers so I don't have to look in the book?  :-)

I do a panadapter (with limited features) and a wattmeter. I have a very

Re: [Elecraft] What became of the Elecraft's KPA1500 and KPA 800

To be inovative, they could make it a full kit, or some assembly 
required like the K3. I think a full kit would be a little daunting for most 
of us, so the 2nd option would be better. It/they have a lot of wiz-bang 
automatic control and proably a lot of surface mount circuitry.

 

It has a built in tuner and I thought that was pretty inovative. 
There aren't too many amps on the market with built in tuners. AND, it would be 
Elecraft quality and would match the other Elecraft equipment.

As far as I know, no one makes a full 1500 watt output, continuous-duty, no
time limit, brick on the key amplifier that covers 160-6 meters with full
QSK and instant on.  It would be nice to have a built in precision
wattmeter, too.

I'm sure some would also like an auto-tuner, antenna switch w/ memories,
dummy load, monitor scope...etc.  It could be optioned just like the K3 so
cost could be adjusted to the budget of the buyer...

 As long as your budget was $10,000. 

:) I think I will continue to turn bandswitch, roller inductor and air-cap
knobs, and use the other $9000 for other stuff.

Re: [Elecraft] What became of the Elecraft's KPA1500 and KPA 800

Apparently someone thinks it is cost effective. What would you need
100% duty cycle at 1500 watts for anyway? We don't have broadcast licences.
I don't think Elecraft was trying to achieve that anyway. 

http://www.steppir.com/SteppirSPE.html

This is the 1K model. SteppIR is just the dealer. It's only rated
for 5 minutes at half power. That's probably enough for a digital QSO. SPE's
website says they have a 2K model that puts out double the power of the 1K.

If the goal was a 100% duty cycle 1500W amp for $5000, then the answer why
it
wasn't produced, has been given. It's not going to happen by anyone, unless
they like losing money.

Was going to be half of that, are two different things. The was part
didn't happen, and won't happen. 

Check the prices of the mosfets and power supply needed, and it will become
obvious.

Apha has the RD money, but they haven't done a SS 1.5KW amp, because it
isn't cost effective.

Not only that, but why would anyone want an amp that would require 3 times
the money to replace mosfets, as opossed to a ceramic tube, that will take a
lot more abuse and be less prone to failure, and probably last a lifetime?

Just the way it is..

mis-stated something and that shook the trees too hard. There are a lot of

I wasn't trying to create an argument.  I was expressing a desire to see my
wish list amp.
I don't know what Elecraft has/had planned.
I never said anything about $5000 or $1.
I never said anything about Alpha
I never said anything about MOSFETS
I said I would like to see a 160-6 meter, continuous duty 1500 watt
amplifier capable of QSK that was instant on.
The current Alphas don't cover 6 meters nor are either one of them instant
on.
Continuous duty doesn't mean someone has to run the amp all the time.  But
if it is built to that spec, it will handle anything I would ever use it for
and do it with headroom. I like that.

Are you trying to argue here? Why do I even need 100W?

I work a lot of stations on the K1 at 5 watts.

But beyond that, someone that wants to use full legal power, will want 100%
duty cycle on CW and digital at full legal power.  100% unlimited transmit
power at 1500 watts, 24x7 if they so desire.

Maybe you aren't trying to argue, but I am talking about full power SS, not
something less.

The fact is, either Alpha will do 1500 watts, on any mode, continuously 24x7
for years, and not minutes.

I like to argue, if you could tell me what I am arguing about. :)

Re: [Elecraft] Elecraft Amps

[srife]

I wouldn't give up my old SB-200, but I would MOST CERTAINLY buy an Elecraft
amplifier should they choose to continue down the path to production. I
think they only need to build one amp at this time though, say in the 800 to
1000 watt range. And I don't think it needs to be 100% duty cycle, but
certainly something that would support digital modes for several minutes (8
to 10)at half power, or maybe full power. An 8 minute transmit time on
digital is a long transmission. I'm no amp expert for sure, but this would
seem like an adequate duty cycle. I don't think they need to design another
Alpha amp that some of us can't afford. I was going to be quite happy with
the KPA-800 for around 3500 bucks (I believe), and it was all automatic with
a tuner. 

As someone stated, making it a modular kit like the K3 is a very
good idea. That way you can buy the basic amp and then add accessories as
you can afford them (automatic rig following, tuner, built in wattmeter,
etc.).

  A watt is a  watt is a watt and it is very difficult to 

conceive an amp that is going to be  so superior (as the K3 is to every 

other XVCR) that someone will give up what  they have to get one.  What 
would 
you add to, or do different from, what is  already available? 

I don't think this is a relevant question. How many K3 owners could have
listed the superior qualities of the K3 in answer to a similar question
about a new transceiver prior to the introduction of the K3? 

 How many K3/K2 owners are even in the market for  an amp?

How many current K3 owners were in the market for a K3 when the K3 was
introduced? And purchasers of a new Elecrft amp need not come only from the
ranks of K2/K3 owners.

Re: [Elecraft] Elecraft Amps

[srife]

Doesn't have to be legal limit. Seems everyone is expressing
something in the less than 1000 watt category.
What ever Elecraft comes out with in this venue is going to be acceptable
price wise because of their superior marketing skill. The KPA-800 with all
the bells and whistles was priced at around 3500 if memory serves me
correctly. I'd pay that for a full featured 800 watt out amp.

I think the modular approach is a better idea. Get the basic amp and
add full control  a tuner, etc,  as you can afford it.

I find it kind of funny that all these folks who want Elecraft to develop

should have, but not a single one so far (including the other met too
answers to this particular post) are able to define how much they'd be
willing to pay for it.  So I'm going to ask it outright ... what price would
be your upper limit for a legal limit amplifier from Elecraft?  Please

I have no doubt that a full featured 1.5KW output SS amp with tuner yada 
yada
would be in the 10,000 or over category. 
And I am sure there is a limited market for that,  but look at how many 
Ameritron
amps are sold,  the SS series,  I have replaced finals in many of the ALS
series amps.  there is nothing special or exotic about those amps,  
making a kit
that used the same type finals,  was truly breakin capable, had proper 
cooling,
and in a same size matching cabinet as the K3 would not be difficult at 
all. 
I do not see any problem for any one who can assemble a K2 to build an amp
kit,  it would be much easier.  And sales would be 10 times more than a 1.5
KW amp at the higher price.  Cover 160 to 6 meters.
I would be interested in one just for a driver for my homebrew amps.  the K3
at 100 watts in insufficient,  so I use an Alpha 99 with the K3,  and it 
works
QSK etc fine.  Close match to the K3 also, black with white labels.

My only suggestion to Elecraft is to not leak any new products until 
they are
very close to release,  outsiders and some insiders are getting the opinion
that if a product is announced you can figure a year to 1 1/2 years 
before you can
actually own it.  Not a real good reputation.  May work for a product 
like the
K3 one time, but repeats on delays will kill the goose that laid the 
golden
egg.
Merv KH7C


 As Paul said Personally, I'd love a small (500w or 600w) solid-state
 amplifier kit  
 that I can build myself (a *real* kit, with soldering iron and  
 everything!). 

 Amen! A kit with soldering would keep the cost down and give us K3 folks
 something to make smoke with!

 My vote is yes for small solid state kit.
