[Elecraft] KPA1500, 4 years old, Intermittent LOW GAIN error.

[paul at paulbaldock.com]

Over the last couple of weeks, I have an intermittent problem with the amp.
On a number of occasions, I have received a LOW GAIN error message. The
output drops from 1400W to a few hundred watts or less as confirmed in the
logging file and my external power meter The problem can go away for a few
days and then return. Cycling the power has no effect, the intermittent may
or may not return almost immediately.

Has anybody experienced a similar problem?

Thanks
