Mike,
The real answer to your question is - do you have a problem with the
KPA500 and your 2M brick amplifier being keyed at the same time?
There should be no RF input to the KPA500 when on 2M, and when on HF+6M
there should be no RF input to your 2M amplifier.
So, are you OK with keying
I don't have room to set it all up right now, but I have done that in the

I do not believe that is the problem. My K3 tells the KAT500 what
frequency it is on as soon as I change frequency on the K3 (or the
KPA500). If not cabled appropriately, then, of course the KAT500 needs a
bit of RF to know what frequency it is on.
The problem is that for some users,
I agree - once you have done the drudgery of setting the tune memories
up for the bands you use, the KPA500 should merely track the K3's VFO.
Seems to me that would be fool proof - maybe???

AUTO - will tune anytime if needed

The K3 does not tell the KAT500 what frequency it is on. It only tells what

Hi all,
Improvements are being tested. In addition to better verification of the

I haven’t had this problem. However, in addition to Igor’s thoughts on a high
reflected signal, here is another thought. A strong signal (like you can have
in contest environment and/or multi-transmitter/multi-antenna set-up) could be
counted by the KAT500 frequency counter resulting in the
As the original poster of this problem topic I have been transfixed by the
subsequent correspondence on the matter. I am still assuming guilt for the
original trigger, but I guess there may be a factor in the KAT 500 algorithms
that may have aided and abetted my gremlin! My next move will be to
Was on 75 this morning and carefully monitoring what is going on with
the tuner. I am running 100 Watts through the KAT500 - the amp is on
standby until this gets fixed. No smoke wanted here hihihi.
Results: Several times during QSO the tuner would click and make noises

What concerns me about all this talk of Reflected Power, local High
Power Stations, etc., is that none of the other users of Automatic
Antenna Tuners (non-Elecraft) have reported similar problems.
I hope the issue can be corrected via firmware. We will be awaiting
the results of their studies.
Hi,
Are you in AUTO mode when this is happening? I found it wise to switch to
manual mode when finishing the quick tune after a QSY. Before I got into
that habit this was happening a number of times. I am running barefoot with
no internal tuner in the K3 so those are not a factor. The MFJ tuner I
Just a thought, how about posting what firmware revision you have in the
KAT500 and or KPA500 when you post about this problem.

I've experienced the same issues others are reporting with the KAT500. The
problem is somewhat intermittent. However, it seemed to happen more frequently
after going to the 1.41 firmware. After reading one of Dick's posts, I checked
the Fault Table just to see what it had in it. I'm seeing the

I reported this problem to support back in February, and though my question
was responded to, it was never really answered -- I've been living with the
problem since.., I'm sure support can look at the case, it was around
February 7 of this year.
Before I switched to KPA500/KAT500, I was running
Same boat here. I gave up my PalStar tuner and a single 3-500 amp that
worked flawlessly for the KAT500 and KPA500. Getting older, I wanted
seamless operation from the PTT to the antenna. I still am wanting that
- so we will see what the coming changes bring us. Meantime, I am
running 100
Sad part is that no one noticed the lack of power.
What's so sad about that? 8-)
The amp should only be used when absolutely needed...
