I can confirm this happens with my Flex 5K, and Alpha 99, using current release
version of PowerSDR. It is difficult to get a stable situation, even as low as
10 watts out on the Flex to safely drive the amp on SSB.

Hi Gerald,
Steve, et. al.
We significantly decreased TR transition times in firmware in order to
deliver the major CW timing improvements in 2.0.19 RC1. It sounds like we
need to take another look to see if that speed improvement is causing a
transition glitch on voice modes. I will meet with the
Easy Ssb peaks equal never exceed the drive setting. If drive is set to 40
watts Ssb peak setting reaches but never exceeds 40 watts.
Easy experiment in test section set
To 40 watts engage two tone it will be above 40. It may surprise you how
much. If using Compression note the difference
CPDR on, and set to 1, is very light compression. It is IMPOSSIBLE for it
to overshoot. If there is overshoot with that on, it is a hardware spike.
I suggest an experiment with CPDR on, set to 1, to see if the ACOM stops
tripping. This would isolate it to the DSP sections working on the

Well, I am going learn not to propose a public hypothesis based on reading
an email. ;) After testing in the lab, there is no glitch whatsoever when
switching Tune on and off. I set the spectrum analyzer to 0 Hz span, which
makes it able to catch the power of real time glitches.

Perhaps. I certainly see what everyone is saying and everyone is right. It
all depends on what you are looking for.
Clearly there needs to be a limiter function
Hi Gerald,
From my own experiments, I'm not convinced that it's a problem with the
ALC algorithm itself (i.e. that it isn't ALC overshoot), but rather
with the placement of the ALC algorithm within the code.
With stock code, my measurements show that severe TX overshooting can
occur, and it
Using my FK5 has frequently causes my Acom2000a to false off. It first occurred
when running 1000w in USB but now is happening more frequently with USB
carefully adjusted so ALC never peaks 0 dbm and the same with the leveler. I
can easily duplicate this problem when in the tune position,
I can attest to Steve's credibility and observation. I have not had my 2000a
on line for 6+ months and just hooked everything back up this weekend. It
will trip with 25 watts, cw, psk, etc. I do not know if there is a spike in
the key up or key down but I would suspect the latter based on what I
Connect an RF sensor(connected to a fast scope) to the cable between the
5000 and the Acom and see if you can catch it in action.

I was planning to use a microcontroller to key and unkey the rig repeatedly
so I have a
