Motorola GM600 for D-star repeater
#mmdvm
|
Jose Alves
Hello everyone,?
I have some GM600 from an old trunking network, and I would like to use them to build some D-Star repeater. I had read some information about but I can't get decent audio from the accessory port on the back of the radio.? I also have read, that is possible to flash the radio into GM950 ( convencional) but I can't find anything about the process and where to get the software. But, If I could use them as they are it will be nice!!! |

I don't know anything about the GM600 but I would say try it and it may very well work. I am using a pair of M1225 and they work just fine. Your bigger challenge will be getting the levels set correctly in the software. Not much to lose my giving it a try.

We had a problem with the pins on the interface we chose to use on a GR-1225.? If the radios you are using have the 16 or 20 pin external connector we chose the wrong pin to route the input or the output (I don't remember which) to use.? We turned the equalization off and it kinda worked, but we had mushy audio and the D-Star data did not propagate to the radio from a net connection.? Turned out there is another pin you can use and it worked like a charm.?
Take a look at the Motorola cables on eBay that one fellow is marketing.? He has it figured out and has one cable for audio interface and another for digital.? When we switched to the pins on the digital cable he sells, we had great audio and data transfer. 73 - Jim? W5ZIT |
