Same thing here, with or without an external amp. CW is as expected. But
when switching to SSB I will get full output (sometimes well over 100 watts)
at any power setting over 11 watts and sometimes cause a shutdown of my
power supply and a reboot of the K2/100. This behavior goes away when I
press RF/ALC to switch the bar display to ALC. I have been told there is a
mod that may cure the problem but I have not done anything. I just make a
point of switching to ALC display whenever I operate SSB.

G'day,
When I run the K2/100 into my Acom 1000 I usually set the requested power
to about 30 - 35W. I seldom drive the amp more than 400 - 500W output.
On CW all is fine but on SSB I notice there is a severe overshoot on the
output for the first syllable after changing to TX and after a few seconds
pause in talking. With the K2/100 barefoot at 30W requested, on CW the RF
bar is steady on 3 but on SSB it overshoots to 4-5 before settling at 3.
At present the K2 is set up as twins with the KPA100 co-located with the
KAT100.
Anyone else noticed this? It would be interesting to put a scope on the
output to monitor what happens to the RF level, unfortunately I don't have
one.
On 40M SSB problem is particularly severe, CW no problem.
Regards,
Mike VP8NO
