Hello there
During the first hours of operation on my K2 sn 7063, I noticed that, when
attempting to copy a weak signal, with AFIL 1 on and maximum AF gain, I hear
processor noise. After that, I realized it is everytime I have AF gain in the
vicinity of maximum. I hear it, during reception

A couple of thoughts.
You didn't mention if the oscillation was occurring with the amp driving an
antenna or a dummy load. The Elecraft transverters have lots of nice features
but they are quite poorly shielded. If you were using an antenna you might be
getting an RF feedback loop

Hello:
I just bought an AA-54 RigExperts analyzer. I am tuning a Buddipole
which I use with my K3 (25+ countries and counting).
The RigExpert says my SWR is 1:2.5 at 14.200Mhz. I also scan the SWR
curve with it and I see that I am 1:3 or lower a couple of 100hz
around the 14.200 center
First off let me state that I do not have any of the equipment Stu is
using. The fact the XV432 likes the 50-ohm termination (dummy load
to the rest of us), says it looks like a termination loading
issue. The Henry 2004 should offer a 50-ohm load at input. Some
amps require input tuning (my
I'm so excited. Tracking shows my 500 will arrive in 2 days. YEH!

Brian,
The consideration over the bulk charge rate is still valid - if the
charger goes into bulk charge state the voltage is higher - AND, if the
receive current is much lower than the bulk charge current, the battery
can be over-charged. To prevent that condition, the bulk charge rate
I took my K3 down to fit a 2nd rx and was reminded of a post by N0SS about
the different way of releasing the rear top corner of the right side panel.
As a reminder, the threaded D-2 block has a threaded pillar attached to it
by a single screw, making it inadvisable to remove the screw at rear
Hi Alexander,
I see this a lot with my K3.
The truth is that the KAT3 is never really out of circuit.
The trick is to enable the KAT3 (Hold ATU Tune), use it to show a low VSWR to
the rigs finals, then disable it (Hold ATU TUNE) again.
You will then find that the VSWR will presented to the rig
Hello Stu2,
Some time ago, I had problems with an oscillating (or at the tip of
starting self-oscillation) XV432. It manifested in such a way, the XV432
being very sensitive to input power levels and jumpy output power when
adjusting the power level. Together with a Mirage D1010 (100W 70cm PA)

TJ,
If you are doing it for the first time, give yourself 8 to 12 hours for
the whole task.
As Alan Wilcox has said, use Specrtrogram for alignment, and become
familiar with its use beforehand since you have a deadline. The use
of Spectrogram 5.17 (and its download) is available from Tom
As a confidence building exercise, try it into a dummy load rather
than the amp. If it works into the dummy load, blame the input if the

Don,
I'm sorry but I fail to understand why you think that the bulk charge mode will
overcharge the battery.
Properly configured, the smart charger won't even completely charge the
battery in the bulk mode, it takes a shift to the higher voltage absorption
(overcharge) mode to completely top

Hi Stan,
I turned on my KRX3 and BSET. My P3 display did not show the VFO B frequency

I think that the aberrant BSET behavior only occurs when the diversity
mode is on. This is related to the front panel display (and the SUB
receiver) switching over to VFO B during BSET, but I don't see it when
not diversity.

During the 7QP this past weekend my KDVR3 Digital Voice Recorder would upon
occasion provide no audio while the transmitter was keyed. I was using N1MM

possible and produced such a great amplifier. It fits

I had the same problem, though it was intermittent. In my case, once the
radio heated up the recording would be truncated, first a little, eventually
playing only the first couple of seconds.
Elecraft swapped out the KDVR, and it's been OK since.
