I just bought a non-working Argosy II 525d that seems to be locked in transmit mode.

I have gotten as far as finding out that pulling connecter #2 on the control board allows the receiver to work seemingly perfectly in all modes on all bands. Plug #2 goes to the key jack and mic jack.

But plug that #2 plug back in and it goes back into transmit mode. Apparently transmitting on all bands.

Where to go next and what to check.

The manual is here.

follow where #2 goes, sounds like a stuck relay...

That's what I thought also but it doesn't use relays, it uses pin diodes. I'm currently learning how pin diodes work. I was hoping someone has had this problem before and might point to their fix.
