Experienced a power drop on my 6300 (running Smart SDR 3.18) again after being sent back for repair twice before.
Tuning and testing into a dummy load.
I very much enjoy this radio ..however it is starting to become very costly and inconvenient with all the shipping and repair costs for the same problem. 
Guess I will have to go thru the testing procedure again to determine the issue before I send it back in for repair.... if I send it back. It may end up in the trash.
.....very discouraged.
After cycling thru the bands at 100 watt tuning (..yes..100 watts for a test) the radio now appears to be producing full output... What gives?

Tim, 

Please open a helpdesk ticket for this and supply all the information from the questions here, plus inform us on how much of a power drop you are experiencing, the temperature of your output devices, the voltage and current of your power supply when the power drops, I haven't read those values in this thread.   Our support team will help you walk through your system. 

We calibrate our radios to produce 100W at 45C with 13.8vdc present at the Anderson connectors on the back of the radio. 

Note that some power drop (~10%) is normal when output devices heat up.  RF output is inversely proportional to the temperature of the output silicon.

Best,
Dan
