Whilst chasing John @G0MHF earlier on 2m FM, I noticed my FT-818 and FT-2980 were showing 18v on the display… rather unusual, so I checked the output of the Watson W-25AM power supply I use in the shack and sure enough, my multimeter also shows an output of around 18v when I transmit on either radio.
It seems stable enough with no current draw, i.e. sticking to 13.8v, but any time I TX it goes well above 13.8v. It still supplies 10+ amps for the FT-2980 on TX, but I’ve disconnected the rigs for now.
Has anyone else come across this before? Google and Reflector searches come back with faults where the voltage goes low, but I can’t see much about it going high. Maybe I’m special ha ha!
Is it time to replace this? I think I paid about £50 for it ten years ago, so it’s done fairly well really.
Thanks & 73, Simon (now chasing from home with battery power only).
