Thanks so much for helping me.


I have just now went into the shop and checked the RX/TX light again, just to be absolutely certain about it; that GREEN light is definitely turning to RED when I key the mike; release the mike key and it returns to green.



As for the meter light dimming, what you describe is probably what is occurring.

I have a group of 12-volt truck batteries that are all connected parallel and maintained by a float charger.

Located at two of my workbenches I have + and - terminals that are wired to these batteries.

I use these 12-volt sources for various electrical component testing and troubleshooting.

So, yes, both radios were connected to the same power source, at the same terminals.


And, in the sake of clarity, that green light most definitely turns to red when the mike is keyed.
