While you guys are on the subject of Motorola Mobile Radios made into repeaters...
The factory frequency programming for the original repeater setup has a "blank" entry for the tx function in the receive radio and the same blank label in the rx frequency of the tx radio. Once someone changes the frequency slot it's not obvious how to restore a blank function into a replacement radio. We've tried blank and zeros into the frequency slot but the software doesn't like something about the entry and defaults back to a number. Any clue how to enter in the "blank" or no-entry function in an unused motorola gm300/m120 mobile radio frequency choice? thanks for your answers... skipp > Mike Morris WA6ILQ <[EMAIL PROTECTED]> wrote: > > At 11:57 AM 03/20/07, you wrote: > >You might want to try pin 14 instead of pin 8. > > > >I just got done interfacing a controller to a GM300 and couldn't get pin 8 > >to work but pin 14 did. > > > >The RSS indicates both pin 8 and 14 are PL/DPL/CSQ detect but only pin 14 > >seems to function properly. > > > >Randy > > RSS will let you assign a function (like RSS) to multiple pins, but > the radio won't work properly if you do that (the programmer that > created that RSS forgot to check for that).
