GM300 external alarm

Post by jim »

Anyone ever have this?

A UHF GM300 that I programmed won't trigger pin 4 upon receiving a call alert. The radio is programmed properly as I've done this many times before. The radio reads "CA" and beeps, but it won't activate pin 4 alarm.

I tried pins 4, 8, 12 and 14 programmed for EXTERNAL ALARM and all do the same. It's also the same whether programmed for HI or LO. All of the programmable output pins do the same thing- nothing.

Can't say I've seen that one before, Jim. Have you tried cleaning the board interconnect pins, just for kicks? I've seen those buggers cause a lot of different problems over the years.

Yep. I did this since it's a common problem.

Strange thing is that pin 4 always has 11.48V on it whether programmed for high or low. This radio has been through several hands and not sure of its history.

We're just going to use a Midian RT2 decoder for this for now. This seems to be the most feasible solution for time vs. money.
