It will also show you important things, like I-Calls, Associations (with talkgroups), new talkgroups, and if it has a digital flag.
Once you run it for a few days or weeks you can go back and look at your logs to see if any activity shows up for those elusive two or three digit talkgroups that have been reported to have digital activity (or encrypted) and the assocated radio ID's and what agency they may belong to.
Note that the alternate control channel is displayed as "a 857.7375".
If you run it on the 2f2d system for a few days you will also notice a pattern to the type one ID's in block 7. Most of the countly scool corporation ID's were in the 57xxx range and the only sizecode that worked for me was "b" (Uniden sizecode - 2).
