Not hearing Troop C

[POBox1142]

This noob needs help. I don't hear traffic from Troop C on my SDS100 scanner. I can listen to traffic on the live radio from this site but nothing on any P25 chs from my radio.

We're going to need a bit more info. You are attempting to monitor them via MOSWIN and not SLATER right? If you have MOSWIN programmed in and are hearing other talk groups/receiving the system then you either don't have the right talk groups in or maybe something is locked out.

 

[POBox1142]

I'm using the preprogrammed talk groups from Sentinel. I have checked them against the talk groups provided by RadioRefer, and they match up. I do hear the point-to-point traffic in SLATER but nothing from the MOSWIN group.

MOSWIN and SLATER are programmed as separate systems, correct?

 

[POBox1142]

Yes, again, this is straight off of the Sentinel program. I made no changes to the talk groups.

 

[scannerowner]

Only thing I can think of would be nobody affiliating with the site you're scanning. What site is it?

 

[POBox1142]

MHP Troop C (Weldon Springs)

MHP Troop C (Weldon Springs)

what MOSWIN site? Imperial, STL City, Weldon Spring?

I have all Sites programmed in on my SDS 100, #36s. I hear them

WOW, I didn't think this would be that hard to explain. If you read all my posts, you should find the info you're asking about has already been stated.
I have an SDS100 scanner.
I'm using the preprogrammed talk groups from Sentinel.
MOSWIN and SLATER are programmed as separate systems, And I'm not talking about SLATER
I'm trying to listen to MHP Troop C (Weldon Springs) (25 channels under this group)
I hear traffic on the online scanner from Broadcastify but not on my scanner.
And to be honest, I don't need to know that you can hear them.

Every time a new person gets in, I have to say the same thing over. Would you mind reading past posts?

You have your physical location set as House Springs.
With that in mind, you may have better luck using the Imperial Moswin site for your area.
Both the Weldon Spring and Imperial sites are very active with Troop C traffic though.
I can receive both Weldon Spring and Imperial sites very well here in Chesterfield. I'd say the Imperial site seems to carry a bit more traffic than the Weldon Spring site does. It's not a huge difference though. So, if you don't have the Imperial site in your list and enabled, give that a try.
I know there are a few low elevation areas around the House Springs area also which could be affecting your reception from the Weldon Spring site.

Also play with the different filters available in the SDS100 menu for the Moswin sites. I have much better reception of the VHF Moswin sites using anything but the SDS models as the VHF Moswin sites are not simulcast. The very wide front end used by the SDS models causes me a lot of problems with Moswin's VHF sites. Of course the SDS model may be the only scanner you own but if you do have one of the earlier P25 models, try them or it on the VHF Moswin Weldon Spring and Imperial sites.
It's a known fact the SDS model may not be a good choice for VHF P25 sites. That statement was made by Uniden's product manager when the SDS models became a reality.

What does your mention of "#36s" mean David? I'm not sure I understand what you mean by #36s.

I’d recommend confirming you are receiving the control channel for the p25 sites you have programmed. One way to do this is using the Analyze feature of the scanner

From the Sds100 manual:

The SDS100 includes some analysis features that can help you find out more information about systems you are scanning.
SYSTEM STATUS
This function displays the signal strength, decode quality, and how busy the system is in an easy- to-decipher display.
To uses this function:
MENU → Analyze → System Status

The scanner prompts for a trunked system to analyze. In order to be analyzed, the system must currently be scannable (in an active Favorites List or Main Database and within the range set for scanning).

Enter the first few letters of the system name, then press E to see a list of all matching systems. Scroll to the desired system, then press E. A list of scannable sites for the system is shown. Scroll to the desired site, then press E. System Status mode starts.

• S=Signal Strength
• Q=Decode Quality
• A=System Activity

From your description, it is not clear to me whether you are scanning the database or whether you have created a Favorite List.

When I said #36s, I was referencing the 436HP and the 536Hps

Thanks!
I kind of assumed that after I looked at what you typed again. It just didn't click in my mind at first.

I'm used to seeing x36HP more than anything which also indicates both models.
It's all good.

Did you ever get this working on your SDS100?

I'd mentioned earlier about issues with the SDS models here. My issues are caused by the 152 MHz paging transmitters within a mile or so of my location. I live smack dab between 4 major hospitals with paging transmitters located on the rooftops of 3 of them. They run very high power levels and basically brute force the signals down into the basement levels of the hospital building.
The paging signals wipe out the front end of my SDS models and prevent them from receiving the Weldon Spring and Imperial sites which both also use 152.xxx frequencies for the voice and/or control channels.
The SDS models have a front end that is between 8 and 10 MHz wide which makes it very susceptible to overload or desense from other strong signals within that spread.

I don't recall if there's a high power paging site near House Springs but if so, that could be the problem.
I know there's a lot of stuff on the tower(s) at PP and 30 which could contain VHF paging. It would probably be on 152.240 or 152.690 or both.
It's been a few years since I spoke with a tech friend that maintained one of the repeaters at those towers though so I don't know what all on them today.

If you don't have any nearby paging signals, your SDS should work fine.

Yes, I can monitor MOHP now. Thanks for your explanations and suggestions. They were beneficial.
