Display blanks out when PTT pressed

Post by AC7NA »

Just completed my build from Sunny. Display works, but goes blank or severely dimmed when PTT is pressed (connected to a dummy load). I can barely read the display on 20M and it says that output is about 2W w 99% efficiency.

Any ideas what might cause this?
