Dave,
Time to contact [email protected].
Unfortunately, they are only open for the next 45 minutes (unless
someone is working late), so be patient while the support folks enjoy
their weekend.

The input too high only happens into a non-resonant load (tuner in circuit).
Also noticed on 20 now when tuner is in operate there is a 3 dB drop in
noise floor.
This is the second time the 3 watt resistor has desoldered itself from the
board and both times the resistor is discolored.
Only one RF path from radios through switching into amp input. Amp output
feeds a 1x4 antenna switch. No other radios transmitting in near proximity.
Definitely something failed on filter board.

Hi All,
KPA-1500 s/n 423
Operating 80 meter SSB running 20 watts drive with tuner engaged for
about
1240 watts out PEP. Remote app shows maximum power handling of 1620 watts.
Out of nowhere I got an input power too high alarm @ 191 watts! The
radio is capable of 100 watts out max and verified is set to 20 watts.
Set tune power to 10 watts.
Meter in amp during standby reads 10 watts.
Switch to operate and immediately get input power too high alarm @ 91
watts.
Switch to 20 meters (resonant antenna). No issue - 10 watts tune is
approximately 400 watts out with no error.
Any ideas?
