P1225/M1225 GR1225 Kaput?

[DeoVindice]

After their old tech passed away last year, I've sort of been drafted to assist with radio matters for a local VFD. They moved to a Harris VHF P25 system a couple of years ago but maintain one of their old analog UHF sites for backup and controlling some flood sirens. It is colocated with another repeater used for our mining operations. During a recent storm, a lightning strike near the tower site tripped the breaker for both repeaters. The mine repeater came back to life no problem once power was restored, but something went wrong with the fire repeater. The display is showing some nonsense rather than the channel number, and it will not transmit. The repeater will not respond to button presses. The RX unit is fine. A Zetron phone patch is connected.

I suspect it's fried. I'd like to replace it with a Quantar and call it a day, but if the old repeater can be saved that's the call that department leadership is likely to make.

It's done. The GR1225 is so old, there's not even one to be found on ebay.

Don't waste your time on dead radio archaeology. Set them up with something modern and call it a day.

I would check the Power Supply first. Also remove the external controller. If it has a phone line it most likely came from there. The 1225 can be had for cheap ($125.00 on Ebay right now - HERE) but I'd push them for a little cash and grab a Quantar if possible. The 1225 while out of support still works well for a backup repeater. My main GMRS sites are all MTR/Quantar but still have some 1225 out and about.

Depending on the case it could have a basic astron style power supply in it. The GR500 wall mount case used a MSI specific power supply.

I’d check the controller. Might have taken a poke which would take out the repeat function and cause the display to go wonky.
