ok so this is the thing. I am on rx and i receive stations but when I ptt then no more Rx. Only when i a power cycle ok/off it is ok again

I have no cw or any wiring related to cw functioks such as npn or side tones...

only tx sense which i have disconncted to check but no joy

any hint to look for? I see no shorts....

Man this is weird
It only happens when I use this power unit it (13.8v 10amps)


but when i use this crappy one it is ok just in case it makes sense to you
13.8v (3ampshhh)

This ^^^^^ is a Switching PSU?

I had a problem like yours with a friend and a 2m base radio... the problem was the PSU oscillates and carry a AC of a few Khz over the 13.8v that drive the radio crazy...

A old analog (Aston) PS cure that...
