Thanks for looking at this post. I have a mtx9000 900mhz radio. I bought it off ebay. I found by trial and error it was programmed with RSS 06.07.0. This radio has major problems. Most of the time I can not access it, it gives me every error in the book. Once in awhile I can assest the code plug. I have noticed it is setup for trunking, but it was not using a system key. The band limits set up in the code plug is the following: 935.01250 - 940.98750. I would like to change the limits on this radio to use the ham bands. I am a newbie with radio programming. I have successfully programmed the ht1000 series radios, but this one is bit beyond me. Any help would be appreciated.
