Help
The CDM would be my pick. However I don't think they will physically fit inside the GR300 housing without modification. I would stay away from the M1225 and CM300 as transmitter radios since their PA heatsink cooling isn't very good. Motorola used to have a notice on the M1225 price pages warning not to use the M1225 series in a repeater configuration.
I don't think you will find any of these radios in the RICK setup manual since the manual was written before these radios were even made. However you can find the RICK setup mentioned in the CDR750 repeater manual since Motorola supported the use of the CDM750/CDM1250 mobile in a repeater configuration. They call it a "basic" controller.
Hello, I traded my GR1225 Repeater for a GR300 Repeater with 2 M120 radios inside.
Ask me why, Idk it was a good friend and I thought if i Trade i would get a repeater i could later use the Power Supply and Case also easy replacement if a radio died.
I ran into Trouble once i swapped and picked up at local dealer for Duplexer/radio tuning.
The Dealer told me that the Controller on the GR300 repeater was bad. M120 radios inside GR300 BTW.
This being said i said no problem i have a spare Controller at my house that came out GR300 with 2 GM300's inside.
The dealer said it may work, He doesnt know but told me to give it a Try.
I went home and tested repeater and worked great!
Then i swapped out the Controller off M120 and Used GM300 Controller Turned on and radios never came on.
Tested radios with diff PSU and DEAD!
Is these 2 M120 Radios fixable?
I dont suspect Fuse blowing cause The Cords dont have Fuse plus the 16 Pin Cord had Voltage going into it so
I suspect the circute board to be fryed.
Any ideas??? Thanks!
