First place to start when trouble shooting is the power supply. Check the voltage as the problem begins to occur. If the receiver works when not transmitting it could be recovering enough to keep the radio running.

(Serial 5540 - K2 MCU 2.04P, K2 IOC 1.09, KSB2 1.08, KPA100 1.10). I mostly use CW but do need SSB at times. SSB had been working fine but recently RF output starts out fine - folks reply to my calls - but it then fades out to zero after about 2 minutes of use. The same thing happens whether I'm running 100 watts or 5. If I turn the rig off for ten minutes or so it will again show full output but again fades quickly to zero. I can still get full output on CW even after this happens. If anyone has any thoughts on simple things I might check, please let me know.
