APX dynamic zone TX priority

[speedway_navigator]

Used a dynamic zone on an APX8000 in conventional mode last night and found out it looks to be using last channel received in scan as the TX channel which I did not want.
My COML said the selected group was TX priority but I proved him wrong and probably looked foolish to the folks on the ops channel when I was trying to talk to my logs folks, but the ops chief was on our channel by the same mistake so we are even.

Is this user programmable to selected the TX priority? I looked through the user manual and see references to Priority-One channel but don't see anything about TX.

You didn't see the field named Designated Voice Tx Member Type? Change Talkback to Selected Channel.

Note that dynamic zones are merely a collection of existing channels from other zones, and therefore there is no separate/unique scan list for the grouping of channels within a dynamic zone. Whatever scan lists are assigned to the conventional personalities of the channels you add to that zone are going to determine the scan list based on the selected channel.

No but this was only my 2nd time using the APX so I was not aware of those options. It's in my notes for next mission.
One of our batteries died after less than 2 hours, I used the battery info screen but got a no info message instead of the usual stuff. It's not an aftermarket, is that a normal response?

Either the battery is shot or hasn't been reconditioned in 14+ days

Thanks for the replies. I emailed another comms buddy who is also a deputy sheriff, he sent me this.
------------------
Our county oes has dynamic zones, our sheriff's office does not. Biggest problem is all of the garbled voice on our
p25. I don't know why our dispatch is so clear but most of our mobiles and portables are not.
I just worked an event, lots of "repeat" requests

Which of course has noting to do with dynamic zones or batteries.

I would suggest a system issue or over expectations of system coverage.

Completely different issues. The "everyone sounds like crap but dispatch" suggests a system issue. Dispatch probably directly controls the station(s) and doesn't receive and re-transmit like the subscribers. Probably an RF issue.. you didn't mention the band? RF is what separates the men from the boys as far as troubleshooting. You can be an IT genius but does nothing for making systems actually work, fundamentals are the exact same as they were 50+ years ago. RF doesn't change, only modulation.

Sorry folks, I chopped off the last line of the deputy's email, he wondered if it had something to do with their APX6000s.
I've seen a firmware update mess with RX audio in scan mode by taking too long to sample the priority channel, this was a Trbo updated to fix a low battery alert starting when the battery hit about 70%.

He's on a P25 phase 1 simulcast system, my first thought is the voting system might have a problem if dispatch TX audio is always good.
