[GreenKeys] PRC-47/CV-2455 Help

[Daniel Jones]

I have one of those.  There is some adjustments in the same area where you switch between 60/20 and a couple of test points to verify.  Also check the fuse as that only supports the loop current and not the blower I have found that sometimes there is just the smallest amount of corrosion.   Its a pretty stout unit so hopefully something simple if not its not to complicated to fix.

The problem is the Mite runs open, when I switch the 47 to cw/fsk the 47 transmits and the blower comes on.  Is my cv bad or am I not doing something right ?
