You can try scanning the frequencies for a particular site, locking
out the CC (but not the Alt CC) but it's a losing proposition. You will
get digital voice mixed in with analog. Further, you will not only not
be able to seperate out different TGs from different agencies (MTO,
MOH), but even within the same agency. Unless there's only one
TG active at a time, you'll get fragmented messages. Try it out,
but you'll probably want to invest in a trunking-capable scanner.
