Greetings hope you folks can follow me on this interesting issue on my pro-164, So here it goes I'm in San Diego County I listen the RCS North and according to RR data base the main control channel that is used is 863.1500 for the north & we are a splinter system, Now I programmed the scanner that way but the scanner won't decode it that way not picking up any id's at all either in open mode or closed mode and id's I put in either, Now here's where it gets interesting I changed the control channel too 863.1625 & put it in normal mode and not splinter and now everything seems to be working right as far as I can tell, So can anybody tell me what's happening is the radio having some type of problem or not, Just bought it off eBay it's like in new condition for $105 the build date is 03A11, On a side note I have 3 other radios 2 unidens a 996t & 250d, Pro 93 that have the control channel 863.1500 and they work great so to me this is odd, Thank You so much for the help
