CLMRN (was CSERN)

[W1KNE]

All TGs, except for the one mentioned by APX7500X2 have been converted to TDMA in the DB. If any singular TG has not changed, it will be changed back, but I tend to doubt that we'll see that.

Also expect to see more and more encryption as time marches forward, so don't be too shocked when you see it. When TGs are confirmed as ENC, even partly, please submit. I can't receive the CLMRN from my house, only when I travel through CT. (Unlike the old 800 system.)

Is that just a hunch or confirmed regarding the Enc. ?

Mta is also still phase 1

SDR Trunk is saying Troop H is encrypted

Not!

I'm hearing Troop H in the clear. 1:36PM

 

[jmorrissey23]

SDR Trunk is saying Troop H is encrypted (at least when this was taken).

The only encryption shown in that screenshot is TG18901 (New Britain PD1) which has always been encrypted. CSP is still clear and is not encrypting their dispatch talkgroups.

Alright I'm glad to see that they haven't gone dark.
But now the question is how to get the scanners to receive it better with this new TDMA? I heard one choked sounding "roger" and that was it in almost two hours. But the TGs keep flashing on the screen.

If you are more than perhaps 5 miles from a site or closer than 1/2 mile to a cell site, you may have a tough time getting a great signal. Trees, hills, weather, RF interference, household or vehicle interference, distance, etc, etc.
It is a crap shoot with scanners, location is key. The problem is that you may not be able to put a scanner where the reception is best. I have a remote location where the house has foil covered insulation. A 996P2 inside hears traffic 80% where a SDS200 sitting next to it was deaf and only heard 5% of the calls clearly. I moved the SDS200 into a garage 15 feet away and reception is excellent. I use the 800MHz rubber duck antenna from the old RS as the extension antenna was only getting me 60-70%. Now my problem is getting the WIFI out of the same house reliably.
Good luck but keep trying different things.

Yeah but they were perfectly fine until yesterday when they made this TDMA switch.

try creating a new P25 system with just the CC frequency and nothing else (no alternates, no TGIDs, etc). I did and found it made a huge difference to the TDMA municipal groups. I didn't explore the why but relocated the radio instead.

[jfr454]

the amount of radio traffic seems similar to me, just Phase 2 now, as does the reception quality on my SDS100.
So much is done over the MDT and cell phones now that they don't use the radio like they use to..

 

[doctordialtone]

This is absolutely true.

I was hearing very little traffic on my 325P2 so I switched to an external Discone and it made a HUGE difference.

I used to receive very well with an INDOOR antenna. (Stock Rubber Duck) Not any more.

Have to check with @WoodburyMan but I'm pretty sure the custom Favorite's List I'm using has that configuration already.

I can't mount anything externally - I don't own the property where I currently reside.

That's because you're in Troop H district. I don't think they made this switch yet.

Well there probably wasn't any switch with the other troops as it was more than likely a scanner issue on those and your ends since everyone else with dsdplus/sdrtrunk has seen no encryption statuses on those ends and heard users fine. Scanners unsurprisingly for some reason tends to have issues with different digital modes especially with simulcast systems. The sds series supposedly should fix lsm issues but I've seen on other forums people still having issues on P25 systems with sds's so idk

I know it's not encryption and figure it is something to do with reception on the units. What I was getting at was wondering if there are any settings on the units that can be tinkered with to try and get them to receive better. Since everything was just fine two days ago before this switchover it's clearly a direct correlation.
I'll be trying it driving up and down the road in a bit to see if that does anything, but since it worked fine from home before this it shouldn't matter.

Well their goal since the beginning was to go to tdma anyways because they wanted municipal departments to join since they told them the system will have great capacity aka having everyone on tdma/phase 2 to achieve that capacity so it was already said the system will be fully tdma or at least mostly. I make my reception horrible intentionally on my sdr's to test the limits on sdr trunk on my local statewide system aswell as CLMRN and I receive them the same whether tdma or fdma even on weak signals. It is 100% scanner issues if you cannot receive primary talkgroups for whatever reason. I'm not saying they are never going to encrypt but right now at least it looks unlikely unless they decide to.

What switch are you referring to?
They have been in Ph 2 since yesterday morning.

What radio (s) are you using. LSM capable (SDS100 / 200) ?

 

[doctordialtone]

Location for my SDS scanners from home hasn't changed so it must be a setting. I hope.

What radio (s) are you using. LSM capable (SDS100 / 200) ?

CLMRN (was CSERN)

She has 2 SDS scanners and a 325P2, among others.

 

[darkness975]

Sds100, sds200, & bcd325p2 are the 3 digital ones.
HPII just listens to analog now and the others are old and boxed.

I had no problem receiving the system with my SDS100 and SDS200 using a custom favorites list a friend gave me until two days ago or whenever they went TDMA
