Thanks, Bob, for the data point.   Gives me an idea of how long things are
going to take.

Re: [Elecraft] AXT1 status?

[Michael Walker]

Rich

I'm sure you'll find this will all work out pretty quickly.  Elecraft is
not Amazon... :)

It is actually pretty hard for a company this size to man phones all day.
I'm sure any voice mail or email you sent will get responded to in a timely
manner.

I've used Elecraft's bits for decades and even calling from Canada and
shipping to me in various places has gone very very well.

QRX a bit... they will get back to you.

[Elecraft] AXT1 status?

[rich hurd WC3T]

I ordered an AXT1 tripod mount about 1 day before the new web site came
online and a bit before Pacificon went on, meaning the chance of my finding
out what’s going on with my order is bordering on “vanishingly small.”
 Phone clls are going to voicemail and emails are not being answered.

I could craft one myself, but I’m just curious as to whether the AXT1 is
awaiting raw materials.   Does anyone know?

Thanks a bunch.

[Elecraft] AX1 on the K2

[Dennis Moore]

Here are a couple of observations on using the AX1 on the K2/10 with 
internal tuner. First off, I know that this is promoted for the KX2/KX3 
and similar radios, the AX1 page doesn't list the K2 as a compatible 
product and probably doesn't get much use in /PM.


With the K2 sitting flat, the AXB1 Whip Bipod legs aren't quite long 
enough to be effective. They do touch the table with maybe 1/2" of space 
between the legs. If you're using the K2 on an uneven surface they may 
not provide any support at all. I think another 1/4" - 1/2" of length 
would solve that. With the bail extended and the front of the K2 
elevated the legs work fine but of course the antenna is no longer 
perfectly vertical


K2 internal tuner tests were performed with the whip fully extended and 
the supplied radial wire laid out to its full length and tightened under 
the ground post as well as it could be. The pre-installed lug does not 
fit around the ground post. Switch position was appropriate for each 
band tested. On 20m the internal tuner found a good match wherever I was 
in the band. That is to be expected as the antenna was designed for 20m 
with no tuner. On 17m the best match I could get was 3.3:1, and on 15m I 
got a 1.1:1 match pretty much throughout the band.


I don't know what caused the issue on 17m since it worked fine on 20 and 
15. On my KX3 the AX1 tuned up fine on all three bands so I don't 
suspect an issue with the antenna, it must be the K2 tuner although it 
tunes other antennas well on 17m. I'll do some more playing around and 
if I get different results I'll post them.

Re: [Elecraft] KPA1500 not amplifying

[n7wy via Elecraft]

Turns out, it is not the KPA1500 not amplifying, but rather the KPA3A final 
amplifier stage in my K3S is acting like it has tubes, not FETs.  It has to 
warm up at 30 watts out, and then the power can  be reduced to 20 watts.  
Weirdly, changing the power level above 20 watts seems to reset tbe behavior so 
it has to be warmed again.  The KPA3A module that is present is the 2nd 
replacement/exchange.  The first 2 had high 2 tone IMD issues on SSB.
My trustworthy K3 is now driving tbe KPA1500 without issues.
Thanks for all the off reflector counsel and 73,
Bob R  n7wy

I built the circuit provided by Elecraft a few months ago to add a
KXPA100 amp to my K2. Its been working great once I got it built
properly. I used two sources of info, the Elecraft circuit

and another page that added some information to the Elecraft page
.

In the Elecraft page they mentioned that both transistors can be
2N, which is what I did. 

The first link is through the Internet Archive site that allows access
to old, saved websitess to allow access to the old Elecraft
site. Someone posted about this just a few days ago, which is how I
learned of it.

Re: [Elecraft] In response to several AX1 questions at Pacificon

One would need to be mindful of the 630m 5 watt and 2200m 1 watt EIRP limits in 
North America, when using such a modified AX1.

And with the right size loading coil could it be used on 630 and 2200

[Elecraft] New Work On My Website

[Jim Brown]

I've just uploaded

1) slides for my Pacificon talk on Transmitting Chokes for the 630M 
Band, and


2) an applications note on Chokes and Transformers for Receiving Antennas.

Both are reports on extensive work over the spring and summer I've done 
on these topics. Thanks to Elecraft Chief Engineer Wayne Burdick, N6KR, 
who supported both projects by providing engineering samples of selected 
cores for my work.

Elecraft did publish an add on circuit to drive an amp from the K2. The bad
news is that I can not find it on their new website. Tom Hammond N0SS (SK)
designed a PC Board for an amp keying circuit which is no longer available.
However he published the schematic which you can find here:

I hope the link works. I have not tried this circuit with a KPA500.

[Elecraft] In response to several AX1 questions at Pacificon

[Wayne Burdick]

Q: What length of coax should I use with the AXT1 tripod adapter?

A: If the whip is close to resonance, which will usually be the case on 20 
meters, coax losses should be fairly small even with longer runs, say up to 15 
feet. When using the AX1 on 17 and 15 meters where an ATU is required, use 3 
feet or less to avoid significant feed point loss. A tripod can be set up very 
close to the operating position at low power levels, so this requirement can be 
easily met.

Q: Is the AX1 being used by SOTA operators? 

A: Yes. But that the AX1 is primarily intended for pedestrian mobile, rapid 
deployment, and as a backup to full size antennas. A longer/higher antenna 
should be used if supports are available and time permits. I always bring wire 
to toss into a tree, but my emphasis is on quickly moving from one spot to the 
next -- literally walking while operating at times -- making the AX1 
indispensable.

Q: Should I call CQ using the AX1 at QRP power levels?

A: If stations are looking for you, as in SOTA operation, sure. But generally 
at QRP levels with any kind of portable antenna it's more productive to call 
other stations, with emphasis on trying strong stations first. Strong stations 
are usually correlated with good propagation, and/or great antennas at their 
end, which benefits both ends of the QSO.

Re: [Elecraft] K2 driving KPA500 / KAT500

[Lou Voerman W2ROW]

Ted,

Elecraft did publish an add on circuit to drive an amp from the K2. The bad
news is that I can not find it on their new website. Tom Hammond N0SS (SK)
designed a PC Board for an amp keying circuit which is no longer available.
However he published the schematic which you can find here:

N0SS K2 amp keying circuit
  

I hope the link works. I have not tried this circuit with a KPA500.
