KPA1500 odd behavior

While operating in the ARRL June VHF test on 6m SSB, I noticed that the main LCD display lost half of its display After a few minutes of on and off transmission. Nothing would bring back the full screen. It would reappear after turning the amp off and then back on. It would then loose half screen again after a few minutes of transmitting. Any ideas?

I’m told this is a known problem. I’ve seen it on 10 meters.

This is a known issue affecting some units. There’s an easy field modification to correct this (or we can do it for you, at no charge). Please contact support.
