Re: Coax recommendation portable UHF base station
I use H155 for portable applications. It's light, low loss - compared to similarly thick cables, stranded central conductor.

MC2100 external modulation input
Hi all, I want to use a MC2100 UHF radio as a transmitter for a digital voice ham radio MMDVM based repeater. It's not the first repeater I'm making but there's a thing. While on other Jedi radios like the GM900, or even the GM1200 that i've flashed the MC2100 from, pin 24 - AUX TX IN2 works great a...

what radio is a MT6000?
Hi all, I have seen for sale some radios that are called Motorola MT6000. Thing is i don't know much about them. From what I see they are pretty much a GP900 with a different label. Am I right? What software is used to program them - is there a separate software or are they recognized as a GP900 or ...

well, your mcmicro is a trunking radio. it is normal for it to act so. if you are not registered on a trunking system your radio will never transmit and as far as I know the trunking mcmicro can not be programmed for conventional operation. there are ways to replace the controller and make the radio...

nope, codeplug was created with DOS RSS and programmed with MTSXLAB.
