TDMA Control Channel Support

[radioman2001]

MTAPD in Metro NYC I believe is P-2 control channel. Which is another Harris system.

Would the Search DB For CC tab and Test Selected Frequencies help find a P25 PII CC?

Can we use the CC's that are found on the Search Tab or do we need to input a cc on the P25RX Config Tab to find a Phase 2 TDMA CC?

Good questions. The test function will not find a TDMA/P2 control channel with the current firmware. I'll work on adding support for that.

Congrats on the milestone! Was the voice channel on the same frequency as the control channel in this case?

I was not logging to file. Recording covered 10 hour period, Only a couple of calls per hour. Will try to log in morning when it appears to be more active.

btt, Suggestion would be to show actual channel slot on the talkgroup log for each entry in lieu of the CC frequency since it does not change.

I'm not sure what lead you to that conclusion, but it's wholly inaccurate. FDMA control channels for all MRRS and Metro-25 sites.

Adjacent and secondary sites for NAC 0x014. Thank you @JSTARS03!

Also pretty sure most of the State talkgroups are FDMA and can roam to those MRRS sites.

Attached is the first TDMA CC based audio recorded with BTT receiver.i consider this to be good reception considering site is 30 miles away. Thanks Todd great job.

Sounds great to me, considering I don't think any PII sounds good and considering you say it's from a site 30 mi away!

Sounds great to me as well! Especially considering that this is a low-quality mp3 format intended for long-term storage/archival. This is a low-bit-rate compressed audio file of compressed voice audio. The actual quality when listening in real-time is considerably better. Thought that might be worth mentioning.
