- Aug 25, 2013Very cool idea. Thinking outside the box is sometimes productive. Kind of like listening in on an older analog trunking system on a non trunk tracker scanner. Just throw in the frequencies and listen. And to find out you get, for the most part, better/farther reception. Cool.

Just for fun I put in all the talk channels of a P25 system, then lock
out the control channel.
Programmed it as a conventional.
In the fringe (distant zone) I find I can pick up most traffic this way
due to the fact the trunk channel
will not decode in the fringe, but the P25 will. Perhaps that is
because there is error correction on the
speech coding and it decodes great, and there is minimal or no error
correction on the control channel.
Also when using a dicriminator tap and a conventional scanner with the
software decoding, now the
trunk radio performs as well as just "Notrunking" the talk channels, in
areas where the control channel is not locked in
(system ID will not display when holding on control channel)
How fun as it greatly multiplies the coverage (as long as you dont mind
getting everything rather than just interesting channels).
