Re-banding retune under way this week. They are doing two frequencies a night.
I'm pretty sure it's the Services system they are re-tuning. The P25 and PS systems are already below 862 MHz. I cannot monitor FFX from my location.

Almost right, 552B and 3C9 systems rebanding. Nine frequencies moving.

So these are the Public Safety and the P25 systems, right?

When they move to new frequencies, do you know (or can/will you say) if the talkgroups will also change?

Can you share the new frequencies for the two systems?

Many thanks!

I don't know the new freqs, but any frequency below FCC ch 120 (853.9875) is moving to above 854.000.. That's 6 for the Public Safety side and 3 for the P25 side.

Yes and 97% of the talkgroups will use the same hex codes, you will have to convert to the new decimal codes for P25 systems.

The Motorola techs are busy now. Mentioned a new channel 12. Running UT I see two frequencies that weren't there yesterday 857.0125 and 858.6125. I haven't yet determined for sure if any freqs were removed but so far today I haven't logged any hits on 853.4875 and 853.9125.

856.5375 has been added to the 552B system.
