Just a random update but lately, I've finally gotten around to just watching the data fly through the control channel for the High Heaven site on the McMinnville MPT1327 system. Quite interesting so far. I've managed to find a couple more voice/talk channels using the custom channel table with the 12.5Khz step and base frequency I found using the required formula. I am also building a large database of radio vs. unit IDs. For now, this is just straight line in audio to the computer from the scanner. I don't have a scanner supported by TrunkView and since the use of this system is really limited to only 3 or 4 agency's 24/7, its not a hassle for me to scan. So I don't think it would be necessary to go and purchase a scanner that is supported, but you never know..
