As I recall, there were some original issues with the connector pins
associated with the KPA-3 PA amp. I recall these were later changed
to gold plated pins. Your description seems to indicate the KPA-3 100
watt amp is dropping off line, leaving only the 10 watt driver stage on
line.

This condition has been seen on my K-3 when operating on 6 meters in FT8 mode.
The K-3 will run for about 45-60 minutes in continuous contact mode, then all
of a sudden will shutdown and only transmit 5 watts to the KPA500 amp. The
PA temp menu shows the amp at 35 degrees C. The FT8 mode uses 15 second
transmissions and cycles 4-5 times in 2 minutes. Normal PA temp is 25 degrees
C before transmitting.
Is anyone else having this issue with the K-3? Serial number of this K-3 is
5192.
