I installed beta rev. 1.87 and selected the BCB=160 and observed my
local AM station on 920 KHz go from S8 to S9+5 with PRE on set at 20-dB.
I then tuned down to 495 KHz and am able to see signals at S9 that
were at noise level before! Noise floor is S6 with BCB=160/PRE
ON. With BCB=NOR
Mine failed with a stereo (not a mono) plug which had been inserted prior to
the
K3 being powered on.
The external speaker of 8 ohms was wired onto the left channel (plug tip),
therefore the right channel did not have a load at the time. Don't know if this
causes a problem.
The fault occurred
I got a variety of suggestions, and decided to go the easiest route
(since it worked) of removing the current limiting resistor and
switching the diode to a schottky diode. The extra diode is required in
my case because the PTT also keys an internal TX preamp whose keying

I am pleased to relate that I seem to have finally nailed this problem, and
I think many of those who gave me helpful advice and the Elecraft design
team will be interested in learning what the final diagnosis and cure turned
out to be. A quick recap: About 2 months ago, operating at about 75W

The Bose Companion speakers are great. The RF shielding seems to work quite
well. Speakers are a little bassy but that can be EQ'd out. I am happy with
mine. You may need to adjustments to get full separation while using VFO's a

The final addition to the AF amp protection circuitry was phased into

We'll also be making this available as a mod kit shortly.
There have been a few other improvements to the AF amp circuitry, all phased

Check the K3-KPA500 AUX cable. It is possible that one of the pins is bent and
is not touching another pin (or the shell), causing the problem. If so, try to
carefully straighten the pin so as not to break it, although most likely you
would need to replace the cable.

I have noticed something similar, but that has nothing to do with the KXPA100.
Whe I switch on NR, the audio is muted. Pushing the PBT button to get NORM
bandwith gets the audio back, but if I try to change the bandwith it is muted
again. Strange. Without NR on there is no such strange

Please be careful if you are replying to a digest of the remailer. A few
times recently I've seen an entire digest quoted in a digest. The last

must reply to the digest, please trim the message!

I believe they cost about $40.00

Good news Ray, I swear by Ian's choke design. It has worked miracles
here. As I mentioned in an earlier post I went straight to the 3 section
GM3SEK choke, in fact two of them, one at each end of the coax section.
Works a treat. I can't speak highly enough of the KPA500/KAT500
combination.

Has anyone written a program to communicate with the K3 through the RS232
port? I want to do some macro programming that is beyond the basic
capability provided by the K3 Utility
Would appreciate contacting someone who has actually written one.

use in the shack, as I wanted stereo and RF immunity particularly.

In the EU we get a warranty on anything we buy, so if they do break within a

Yes Brian, it may have been something very simple that had failed and I am sure
you could have fixed it for them if they had thought to ask you, what a shame.

Hi Ed,
This has happened to me. I heat my house with a wood stove and the

Hi to the group.
I hope the group wasn't thinking my test conditions were my recommendations for
running the KX3-KXPA100 station. I purposely set it up under marginal
conditions to test the new software and originally to test the old software.
The battery is over 4 years old and I may replace
I've written programs for both Win Mac that talk to the K3 via RS232, but

If you turned it on when its temperature was below 0 degF, that can happen.
The programmer's bug-a-boo of a maximum number of 255 and a minimum of

When the numbers decrease to below 000, the next lower number is 255 -
which indicates a really hot K2! Even if it is
I happen to think that the K line and the off-centre-fed dipole make for an
ideal compact station, particularly for those with very restricted land on

The easy way is to hold the dash on the bug. If you want to use a straight key
