When I was in DC today with my KNG2 radio it listed all the astro channel ID's for the DC Rdo network which turned out to be 6 in all with a mix of 6.25 spacing and 12.5 spacing. I get home and run Unitrunker with 2 SDR dongles with one of them being airspy, I am only getting 3 astro channel ID's both with 2 of them in the 6.25 spacing category only and the 3rd one is 12.5 in 935.0125 range. Does anyone have any ideas why i am only receiving the 6.25 spacing only? The only reason that I can think of it is picking up FDMA only..

3 of them are for Phase 1 and use the IDEN message, 3 of them are for Phase 2 and use a separate TDMA IDEN message. Your SDR my not be decoding the TDMA IDEN message,
