I have now downloaded Build 3 and have it running in VC. It does appear to be logging the talk group in the column DATA, TGID: 123 in the column Channel Tag, and the word Unknown in the column called Department.
In other words, at first look, it appears to be working Perfectly! Congratulaions it seems the problem(s) are solved.
Of course, I have to now move to regular operation and see that it logs 'regular traffic' as well!
Logging overnight on my PC, Build 3 appears to have logged both Unknown and 'regular' traffic fine. This version looks like a Winner!
Thanks for your continuing efforts, Gommert.
I don't see how any serious HP-1 user can do without this latest version of Arc Patrol if they are trying to explore new users on a trunking system.
p.s. - it would be a great addition if you could find time to update documentation (user manual(s))...
