I think the S-meter issue has been muted, we
better give it a rest for a while.

I am running beta 2.63/1.95 firmware. Although power output is normal in CW,
USB and LSB modes (setting SSB to operate with several bars of ALC), I can
only get about 10-20W out on PSK31 and 50-60W out on AFSK before ALC kicks
in. This is the case whether I use LINE IN or FP/RP MIC connections for
I had Elecraft install my KRX3 and KXV3 and all seems to be operating well in

One thing I do notice though is that the main rx audio seems to drop
significantly in the left headphone channel when I turn on the sub rx.
After continuing to play around, it appears there is

Hi Jerry,
The setup for the K3 in PSK31 is quite different from the way you set up
most other radios. See
http://n2.nabble.com/K3-Transmit-IMD-td466326.html#a466329 for an
explanation. There was a discussion about this just over a month ago on this
reflector, as a result of which I personally
The frequency as always is plus or minus the QRM. Note the later start
time of 1000 hours to try and minimise European QRM.

Jerry,
I am confused about your saying before ALC kicks in, and it makes me
wonder if you are using enough audio gain.
The latest recommendation from Lyle is to increase the line-in gain (or
the soundcard gain) until you have 4 to 5 bars indicated on the 'ALC'
bargraph. At that level, Lyle
I hesitate to reply cuz my experience is so limited. Try this if you haven't

Turn on the SUB, turn on B SET, hit the ANT button until Main appears. When

Gary gave you good advice Bruce. I'd check two other things:
1. Go into the config menu for KRX3 and check that it's set for Ant=Atu in
your case.
2. Check that your subrx filters are set up properly. I recommend using the

I have an off-reflector friend who's just built a K1. He asks
if it can be mated with a KPA-100, perhaps in an EC-2?
Off hand, I'd say there are ... at least ... antenna relaying
issues involved.
He realizes that if this is possible he might not achieve the
full 100W output from the KPA-100.
Ken-
My understanding is that the KPA100 needs communications from the K2 via the
auxbus to operate. It was not intended to work with other rigs.
That said, maybe someone with actual experience will chime in with another
opinion.

Ken,
Not possible. The KPA100 must communicate with the base K2 for band
selection, power control, T/R switching, and other functions. The K1
does not have the necessary signals to communicate with the KPA100.
The KPA100 was designed as an integral part of the K2 rather than 'just

I purchased a K2 kit that was bought in 1999 and have been upgrading it to B.
This kit was never built and the crystals are a different frequency than the
newer ones.
Can I use the old crystals or will it suffer performance with the old ones?
The B version BFO calls for 4.9152 MHz and the ones
How much less than 150 ohms, Roger?
The resistance on the K3 used to write and test that procedure is just about
200 ohms, no matter which way the meter leads are oriented. So 150 ohms
seemed a safe value to specify.
Since you chose to remove the original choke, did you desolder or clip the

John,
It is rare to change the BFO crystals as part of an A to B upgrade.
The BFO crystals should be usable, but the IF crystals should be
replaced with new ones. The crystals were controlled for motional
inductance starting at about SN 2560 and result in a much better
filter. Elecraft

Most laptop built-in sound cards won't work for SDR because they only
have mono (microphone) input. SDR requires a stereo (line) input.

Fred,
The real answer depends on your antenna system, and not on the gain of
the preamp.
You should try each band with the preamp off and then on. If attaching
the antenna results in an increase in received noise, you have the K3
set for the best usable sensitivity. If that condition is
