Hello! I have recently aquired a Motorola GTX Mobile radio. These radios normally have a high bandsplit of 866Mhz. I have sucessfully bypassed this, allowing me to setup conventional channels above 866 just fine. They work fine both on receive and transmit. Here's is the problem: When I enter a trunked system above 866 and set the radio to listen to a talkgroup, theis weird thing happens... Basically, the radio is quiet the whole time, but when the talkgroup becomes active, the GTX's speaker opens up as if trying to tune into the repeater, but there is only static, so it goes quiet again, and it continuously does this. The timing is as follows... The radio is quiet for however long, then when the TG goes active, the radio instantly opens the squelch, waits .5 seconds, then closes the squelch, waits another 1.5 seconds, and repeats (open squelch)....This all stops when the TG stops being active.
I asked a friend, and he told me the cause of this may be the controller inside the radio. He was reminding me that when the Trunking controller sends out for a channel, it sends out a channel number, but not the actual frequency. He suggested that MAYBE this radio's mapping is different as far as those number go?
If anyone knows anything about making this GTX Mobile to trunking above 866, please write below! I REEEEALLLLYYY appriciate it. I dont really want to go out and buy a Spectra since I already have this GTX here and it's a nicer radio (as far as cosmetics and mounting in the truck. LOL )....
