[op25-dev] suggestion: logging output

In normal operation, it seems that stderr.2 captures mainly messages retuning to the control channel (which is what helped me catch the issue noted in my other message, so that's not all bad). But I think it would be very useful to have the option to log each channel/talkgroup handoff (I'm not sure of the terminology). In particular, building a list of talkgroups would be handy to identify ones that don't have tags. I don't know the difficulty involved, I think it would be really nice to include something like this: 1434343.003423423 frequency: 853.500 talkgroup: 57234 for each handoff. You could then use command line tools (cut, sort, uniq) to build up channel and talkgroup lists. For extra credit, do this at different debug levels. For example, default would print only tuning errors and other things that need user attention. Then at -v 5 print handoffs, at -v 6 print handoffs plus control channel, and leave -v 10 and above as-is. Or maybe add a new command line option to specify the output file. I'm willing to work on this. If I have time, I'll play around with it this week. I will happily accept hints on how to go about it. 73, John
