Hello,

I've been working over here for a few weeks. Found a lot of the sites and the frequencies/talkgroups/slots active, but in the process, I discovered that some of the licensed frequencies are being used on a 4+ site Motorola Capacity Plus system. There are sites co-located with the conventional linked DMR towers at Cotton Belt Rd (Mansfield North is how I labeled it), Keithville, Hunter Rd (Stanley) and Logansport HS. There is also a site 7 broadcasting a rest channel on 155.8125 but I have not been able to track down the signal location yet. The only traffic on it is on talkgroup 2 which is the SO dispatcher only on the main dispatch channel.

For the most part, the EMS and SO use their 5 site conventional linked VHF DMR systems which also relay data. The sites are Hunter Rd (Stanley), SO/Jail (Mansfield West), Cotton Belt Rd (Mansfield North), Keithville and Rambin. I have unfortunately not heard any transmissions from Rambin yet because it is so far from where I am working and staying, but there are several frequencies licensed down there. I think they are taking a little liberty with their frequency assignments as 154.145 is licensed for Rambin, but broadcasting from Stanley. I verified them by parking close to the towers and running no antenna.

There are still some fire departments to verify the talkgroups and slots, but I know the repeaters are active due to DMR data bursts with AVL/LRRP. Its a big parish to cover, but unique in its DMR approach. There has been no P25 activity that is related to the county on LWIN other than state troopers.

Have verified that Red River parish fire also switched to DMR next door. They are using 154.385 with CC 1, TG 101, and DeSoto FPD 2 (Keatchie) is using 154.385 with CC 11, TG 36.

Having a tough time with EMS here in DeSoto Parish. I'm running an SDS100, and have heard chatter on the sheriff frequencies (which seem good by the way) referencing an EMS call they were responding too, and I never heard a peep on the EMS channels I was simultaneously monitoring.

I'll note that the 155.865 tower is causing the scanner to hang a ton....looks like it's flashing DMR/CAP+. Not entirely sure I have these guys programmed right but I've tried everything from importing straight in with Sentinel and even adding manually on the scanner using the DMR/CAP+ guide video that Boy with a Scanner does in YouTube.

Anyone having EMS luck in DeSoto?

They simulcast multiple repeaters in DMR mode and were conventional a few months back the last time I was over there. Try the other EMS repeaters listed on the database page and maybe remove the color code and search for new colors if they changed it.

Update a year later, sorry. They've changed a few things here:

The Stanley tower got moved to Logansport on the Cap+ tower by the school.
The Rambin tower that was not set up in 2019/2020 was moved to Pelican. It may be online for both SO and EMS but too far for me currently.

EMS is still conventional from what I can tell, but networked like before. The Keithville tower was moved closer to Stonewall. 155.865 buzzes with conventional DMR BS with the roaming beacon so the radios automatically swap towers when signal degrades. The capacity plus system is still running but I haven't picked up any traffic on it during the day time. I personally think it is used for schools more so than first responders since most sites are located near schools, but I have yet to verify that.

I cleanup up the database page and added a DMR conventional networked system for the SO and EMS since that is what they are in fact using. The fire departments remain on the main page since their repeaters are not networked together and talkgroups are unique to each site.

I work for a different company now and am in West Texas. I would put all the licensed frequencies for DeSoto Parish Sheriff and EMS into the scanner and see what comes across. They have both the conventional networked DMR system for SO and EMS and the networked Capacity Plus system for schools and security and they all use VHF frequencies.
