If it were me (and this is just me)No, Not in the freq file yet i was just watching the wave spectrum and the cc window box where the talk group was coming across. Maybe that the wrong way to determine them. I'm still a novice at this hahahah
1. I would park the CC copy on the L4-7 control channel
2. I would tune the FMP24-VC to a freq that you want to check and see if its part of that site
Then I'd watch the CC DSDPlus for TG 181 activity and then watch the VC DSDplus side to see if there is audio when TG 181 is active on the CC side and I would note what it says at the bottom of the VC DSDPlus screen.
I would do that for each and every frequency that you presume could be part of that site as a voice frequency
It would take a while, but I think that is the better way to do it.
Also, just keep in mind that just because there are two LSN pairs and "CC" is listed separate in the channel activity window, it doesn't mean that there are actually three frequencies. It could mean that. But it could also mean that there hasn't been voice activity seen on the CC, and that's the only way DSDPlus would determine the LSNs for the CC. You hit it lucky on L4-23 because obviously at some point there was voice traffic on the CC that allowed DSDPlus to determine the LSNs for the CC.
Remember, each freq has two timeslots. Although it is most common for T3 CCs to never have voice traffic (both slots used for data), it is possible for a T3 CC to have data on one LSN (slot) while having voice on the other. If there is never voice copied on the L4-7 control channel, you'll never really know what it's LSNs are.
