[Elecraft] KPA500 Low Power on 6M

[Terry Burkholder]

I have a new KPA500. It works well on all HF bands but on six meters 
with any more than 280 watts out I get a "PA DISS" fault. This is into a 
500 watt dummy load. External Diawa CN 801 power meter power reading 
agrees with the KPA500 wattmeter.

At 280 Watts out the drive, from the K3, on six meters is 20 Watts, HV 
74 volts no load, 60 volts loaded, current 13.6 A SWR 1:1

Any suggestions?

Thanks, Terry N4TB
