2011年9月8日 · The GR1225 is a nifty little repeater. Best located on a farm silo. In a dense RF environment, they need additional filtering to help keep the "crap" out. If you install a GR1225 in a high RF environment with just the flat pack duplexers, your on your own. Changing PL's is just a band aid to the real problem.

2024年8月5日 · A GR1225 seller on ebay commented that the duplexer will only pass frequencies that are within .25 MHz of each other if duplexer is tuned for that frequency; example: 463.675 thru 463.925. Is that true? Using a power/swr meter is there a process to tell where my transmit and receive frequencies that the duplexer will allow to pass thru?

2020年12月11日 · Hello Everyone, I just purchased a Motorola GR1225 UHF 40watt repeater (model number M44GRC90C2AA) with internal duplexer. This is the first repeater I have ever purchased and will ever have any experience with. My goal is to put this up at my residence for my family as I have a GMRS license...

Scenario: Im trying to get space on a water tower in town for the antenna. I have the repeater setup with 16 "channels" all the same freq, but different PL/DPL on each one.

2016年5月9日 · GR1225 FR-4000 MTR2000 The channel for the GR1225 can be "remotely" changed through the accessory connector but it is somewhat difficult to set up and requires some sort of interface box. There are 4 channel lines out of the accessory connector and depending on which ones you ground (or take high, I forget) selects the channel.

2017年9月2日 · The repeater is a single duplex radio and its model is a GR1225. It is basically the same hardware as the M1225 but contains a internal controller. If this was indeed a Maxtrac this would be a non issue as VCO alignment on the Maxtrac radio is done with a multi-meter, SINAD meter, Scope/SM and a non conductive tweaker.
