Hi Vic, thanks.
That's the first thing I tried, should have included my checks in the
first message. Here is what I've done so far.
Put a dummy load on the antenna 1 port
Confirmed that the amp was on antenna port one
Checked the SWR between the K3 and the amp 1.1 without the K3 tuner
Re-seated all the cables on the KPA1500 rear panel
Tried the amp again and it works. I have no idea what cable fixed the
problem. I am using a back to back cable between the K3 and the KPA1500
AUX ports but it's been installed for months and I've experienced no
problems. We'll find out in tomorrow's CWT. I think I'll run the amp
at 900 watts until I gain confidence.
WOW! WHAT A RELIEF!

The first thing to do with any amplifier failure is to try it with a dummy
load. If the problem still occurs, you can rule out SWR or RF feedback
problems. It doesn’t seem like any of the above if it occurs on all bands, but
it’s easy and a good start to a systematic diagnosis.

My KPA1500 is faulting with a low gain alarm ration 6. This is with 23 watts
input 160-10 meters. Any advice?
Thanks, Ed W5TM
