Good you got it working. As an FYI I built a GPS from a ham led drone module. Until I shielded the cable it wouldn’t connect properly. These things don’t like noise for sure.

It dawned on me that the wall wart might be introducing some noise, so I prepared another cable to plug in to the PTT socket, wired according to Hans' diagram. Problem solved. Wall wart bad, filtered regulated +5V good. Also I keep a dummy load attached at all times in case some dummy does something I'll regret.
