I recall something like 14 contacts needed for PTT on the G50. A mixture of NO and NC contacts. It is a big task to get PTT on this radio. Don't even bother unless the band switch is toast.
Pete W1VZR told me that he once did in fact do a PTT for someone who had to have it. I think he said it took 4 relays
Oh and the Communicators are not at all like the G50. Some similarity as far as the audio, but that is about it. The PTT and power supplies of both series are as different as night and day.
So keep reaching for that blue knob to TX. Just talk longer and switch less...the old buzzard motto.
