Gary, Although I have not worked with the 900 MHz versions of the MTR2000, I doubt that it is possible to tweak the CPS to change the band edges. Both the receiver and the PA have their band ranges embedded into their internal chips, so hacking the CPS cannot change that. Urban legends about CPS hacks are a dime a dozen, but curiously, none of them ever can be put on display in front of experts. The excuse for no proof always is something like "a friend of my cousin discovered how to do it, but he was mugged last week and now has amnesia." The MTR2000 is a great machine, in my opinion- I have six of them in service now- but they do not lend themselves to hacking out of band.

The 900 MHz MTR has transmitter band limits of 935-941 MHz. It would seem the lower limit must be edited to allow 927 MHz freqs to be programmed. Anyone done this? If so, which version RSS did you edit? Also, which file(s) must be edited? Which offset(s) as well? Please reply direct to me (off the list) if you have any helpful info. Thanks, Gary
