Yes, today I let Pro96com run for about 9 hours and found exactly what RR database showed for the Poplar Bluff Tower which does not include 158.835 MHz
This is an odd one.
Did you by chance take note of any UIDs (or RIDs) seen by Pro96com on this 158.835 frequency as well as those seen on average on the Moswin Poplar Bluff site 3-008?
I guess just those used by the known Butler County talkgroup range that are listed would be the ones to watch unless actual Troop E users are the ones using it.
Seeing that the comms don't correlate in time should rule out this being used as some type of mobile extender.
It's also interesting that the frequency is tagged as a 'Public Works' service type unless that was just a typo.
I wonder if the City of Poplar Bluff is using it in the Butler county talkgroup range. I'd think the RIDs seen by Pro96com should be similar between the Poplar Bluff city PD frequency (151.0475) and any radios seen using this 158.835 frequency though. It's still strange it's licensed under the state Moswin site license for the Poplar Bluff site though.
The power limits and station class types all point to mobile use only when you look at the frequencies of 158.835 and what appears to be its input frequency of 153.800 under the Moswin call sign of WQNW995.
How long ago was 158.835 Conventional listed here in the RRDB for Butler County?
Myself and another friend here in the St Louis area both received P25 signals from the 158.835 frequency when the VHF band conditions across the state were doing some crazy things very recently. Unfortunately I did not have any logging or audio recording running when this one was spotted.
I only remember being surprised when I found out where the signal was from. That's a pretty good haul from Poplar Bluff up to the St Louis area.
I remember seeing the 1C8 NAC in DSDPlus but I didn't even notice it was apparently not a voice channel on the Poplar Bluff Moswin 3-008 site when it was heard here. I only associated the signal as a Moswin site voice channel when I saw the NAC in DSD+ but never looked further into the signal until seeing your post in the thread about the frequency.
I wish I'd have paid more attention to what DSD+ was showing me as it should have listed any talkgroups and UIDs seen when voice was heard on the frequency here, I lost my DSD+ logs for those days of the VHF band openings due to a downgrade from Win 8.1 back to Win 7.
I can't say I've ever noticed any other VHF Moswin sites licensed with an oddball frequency pair like site 3-008 has.
Seeing the same site NAC as site 3-008 uses pretty much says it's not a mistake in the license.
I did find a modification marked as Inactive dated 12/31/2013 that has an attachment with the same date. It shows that 158.835 has something to do with the US Department of Agriculture.
ULS Application - Public Safety Pool, Trunked - 0006075933 - MISSOURI, STATE OF - Administration
An Amendment was added and granted on 04/16/2014 with the same attachments as were submitted on 12/31/2013.
Maybe this has something to do with the oddity of this site and frequency.
The frequency of 158.835 has been listed without a station class of FB8 ever since the initial licensing back in June of 2011.
There was also an attachment included on 12/31/2013 that references the US Department of Justice but it does not give any frequency detail.
That also make me wonder if 158.835 has something to do with the agreement with the Dept. of Justice.
It's an oddball for sure.
