[Elecraft] K3/KPA500/KAT500 Help

[Fred Smith]

Last night when I went to bed all was working perfectly with my setup radio,
tuner, amp this when I turned the amp, radio on tuner powers up when power
supply is turned on nothing talks to each other.

 

Turned everything off and tried again same thing amp, radio will not change
bands together nor will the tuner tune the antenna. I powered all down again
and shut down power supply and turned off power on rear on rear of amp.
Powered all back up same thing no error messages of any kind.

 

Any suggestions?
