Although I have no problem receiving the Burl PD using the 3 Beaverdale channels, I've been checking this discussion several times a day. I am just curious about what is going on with this issue and hope someone comes up with an answer. My 996P2 gets the PD just fine all day every day. I live in town, have no outside antenna, and I am in a large apartment complex so my location is not ideal.
That still has to be the weirdest part of the entire thing...the fact that some of yall aren't having issues, and some of us are. If it was just me I'd think I was the problem, but as you know there are several other in this forum and outside of it that are in the same boat.

I would like to chime in on this and say that for the last about 2 weeks, ive been having problems with my Uniden SDS100 and Uniden SDS200 not receiving anything from DMCSO, WBPD and BPD. Im going to try and program those talkgroups but use the Lee Co Simulcast site and see if i can hear them that way. I live in Danville for reference and never had any issues up until now.

Can you provide your general location wrt the Beaverdale tower site - how many miles away and from what direction? How have you programmed your 996P2? Is it programmed to track a trunked radio system (which only requires using the active control channel) or are you scanning the three frequencies conventionally? The Beaverdale site is a stand-alone resource (aka not simulcast) so a 996P2 should receive it with no issues.

Based on your observation, it seems like the Beaverdale site is up and BPD has not enabled full-time encryption since you say that you are able to hear them off the Beaverdale site. It's possible that they have instituted part-time encryption which *could* be at least part of the issue. Another issue *could* be that the Beaverdale site's transmit antenna(s) may have experienced a failure or shifted out of alignment. If I was using an SDS scanner and experienced issues like what is being reported, I would create a test config that contains ONLY the Beaverdale site and nothing else and monitor that for a few days. I might even drive to different areas around the site to determine its service area. If I was using an SDS100, I'd replace the stock antenna and use a Remtronics 700 / 800 MHz antenna which is in-band for ISICS and works decently for UHF and VHF.

According to google maps I am 7.98 miles from the tower. Slightly east of due south. Using trunked with just the 3 freqs and using ID Search mode. No other settings changed.

So i made a test file with all the talkgroups from DMCo but used the Lee Co Simulcast site and now i can hear the sheriff, bpd and wbpd again. Im starting to think that the Beaverdale site is having issues.

Quite literally what ive done btw.

SDS200, drove right up to the damn tower with only Beaverdale programmed and guess what? Still wont do anything other than the flashing from my videos.

And as you can see im not the only one experiencing this now, but we have people saying their fine too like BW.

Its clearly not something programming or even hardware related if collectively several people all at once lost the ability to hear this specific site. Its something to do with the site itself, what makes no sense is how some can still hear it.

ID Search huh? Next time BPD comes thru look at the TG ID and see if maybe they didnt change TGs, imagine the whole time this was the issue🤣

Considering that the Beaverdale site is directional with an azimuth pointed to 290 deg and a beamwidth of 180 deg, you are just inside / adjacent to the southern lobe of the Beaverdale site footprint, hence your ability to receive the site adequately. Assuming the transmit antenna is mounted on the upper third of a 100m tower, a user should expect good receive performance at least 8-12 miles from the site, and more depending on the gain performance of the transmit antenna and if the tower is taller than 100m.

From what I have seen, the antenna is at the top of the tower. And I believe it is taller than 100m but ofc thats visual estimation.

I dont think thats the issue because i just heard them on my scanner through the Lee Co Simulcast site. Im thinking they are either having problems with the site or they are moving Des Moines County over to simulcast and havent finished upgrading it yet.

They still are on 26601 but also use 26602 and 26603 for car to car stuff.

Wow that amazes me. I have 3 external antennas and I get nothing and haven't for weeks now. I don't understand it at all. Please tell me how your 996P2 is programmed. I don't think it's a programming issue but I want to rule that out.

If anyone has an extra $35 and a Windows PC, they could purchase a good Nooelec SDR and download free Unitrunker 2 software to map out the system properly - much more precise info can be obtained about system and sites via control channel monitoring software. Another piece of software that many find useful is SDR# or similar spectrum monitoring software. You tune it to a control channel frequency to see if is actually in use, and its relative power level and quality at your receive location. There is a bit of a learning curve and technique involved, but in my opinion a better method to diagnose these types of problems. Plenty of info on this site about how to use these tools.

I manually programmed it about 5 years ago when I first learned of ISICS. Since it has been so long ago I don't remember what I did step by step. Basically just made a system with the 3 Beaverdale freqs and used ID SEARCH. Since there was nothing of interest on there at that time it has been locked out for years until the city and county started using it. I just unlocked it and been hearing everything since. I have never messed with settings such as filters or threshold. I kind of get the feeling that some users get so involved changing all that stuff and then things get messed up. I've read for years you have to set the squelch at 2 but never believed it. I set my squelch around 8 to 10.

On LSM sites, you have to have your squelch set to 2 or it won't stop on the site.

Has site 66 been identified in Lee county as shown on the attached map? Based on the map, it appears "66" is separate from the "56" LSM.

In other parts of the state;

1) Is Clinton site 122 (700mhz) online?

2) is Sumner site 9 online, callsign WSES913?

3) What is site 53 in Oakland? This is likely the Cass County LSM system for whoever thought it was Oakland.

Tim

I made a Keokuk turn yesterday. I did search for site 66. Nothing found. Lee Co LSM wasn't reporting it as a neighbor either. I'm guessing the site doesn't actually exist.

If 66 doesnt exist then why is Lee Co simulcast?
Per the ISICS coverage map, the Lee County simulcast cell appears to consist of four RF sites. While I’m speculating somewhat, it’s likely that the former Donnellson tower location was incorporated into this LSM simulcast buildout, along with other existing county tower sites. This would be consistent with Lee County’s status as a Level 4 ISICS user, meaning the county owns and operates local infrastructure that’s tied directly into the statewide ISICS core.
