Default Washington Co Interference

Have occasionally been receiving Washington County (SysID 29E on control channel 154.9650) traffic bleeding over onto DaneCom control channel 154.9725. Goes to show that channel separation becomes more and more important in crowded bands, especially during even mild band openings or morning tropo. Washington Co isn't that far from Dane Co, and this separation isn't adequate. Most folks in at least NE Dane Co can pick up Washington Co with handhelds.

While this is on a BCD996T, issues will remain for other scanners, especially if they're on good antenna systems. Perhaps some newer scanners will allow putting in a system id filter??

Washington county has 5 different control channels they can use according to the database. To cause the least amount of problems, I think 154.9875 would be the best one for them to use as a control channel.
154.965 too close to danecom 154.9725
155.250 too close to danecom 155.2425
155.535 too close to danecom 155.5275 and kenosha pd 155.5275
154.740 (stoughton pd) and too close to whitewater pd on 154.7475

Last night I was getting something full strength on Dane Comm. And yes, it did sound like Washington CO. I've heard this quite often in the past and I was just assuming that it was a patch for coverage testing.

Too close for comfort. If you see a talk group ID of 57xxx you'll know it's a Washington Co unit, 13xxx you'll know it's a Dane Co unit. I have not heard any significant testing on DaneCom.

I can pick it up on my 396XT with stock antenna in a vehicle or light building when there is tropo.

Default Wash Co/Dane Com

I think will be ok :-) LOL Keeping the radios in narrowband mode and using NACs should keep the systems in operation with no real issues.(smiling at my P25 scanner radio expert brothers.. oh what would we do with out you :-)) There are times I even I get frustrated that the radios dont act like the scanners and the scanners dont act like the radios. Then I remember oh ya.. the scanner only cost me $500 bucks and my Unity radio was $4000. Still, I understand the frustration. Esp. when it comes to Simulcast systems.

Will see what the future brings when Dane Com brings more channels online. We work closely with them already to assist them anyway we can, and look forward to coexsisting with the other Harris system to the West :-)

-Keep scanning and keep streaming, the truth is out there somewhere-

Default Analog Tac Testing

Has testing started on the analog tac channels? I'm receiving an open carrier on 154.070 (Fire D) from the I-94 tower and on 155.790 (Sheriff 6) from somewhere else. Also heard Sheriff 5 is out of service and there was cross talk from Fire B to EMS E.

As of tonight I have been hearing a "test 1 2 test 1 2" on TG 4946 and 4947 on the new Danecom...

What firmware is best for the 396XT? I'm using 1.10.00 and can't lock on the cc since simulcasting started. Has anyone tried 1.11.01?

Good luck using a scanner with DaneCom unless you have omnidirectional antenna. DaneCom is using LSM so all the scanners will have trouble decoding. My PSR-800 is worthless unless I lay the receiver on its side and point it towards a DaneCom tower.

TG 4946 and 4947 are testing talk groups. I don't recognize 13898.

Default DaneCom

Can yuou tell us what LSM is and how it affects the scanner's ability to decode the signal? This is the first I've heard that DaneCom is going to be a problem.

(LSM) Linear Simulcasting Modulation.

Here's a link breaking it down: http://gdesales.com/knowledgebase/si...20networks.pdf

It's not that DaneCom is going to be a problem; it wasn't built for digital scanners. Wiscom is easy to decode because all the tower sites are broadcasting C4FM, DaneCom is using CQPSK.

Now hearing what sounds like a simulcast from Madison PD Channel 1 to TG 13601 on DaneCom. Audio not the best ...

I've made some progress with my 396XT settings

P25 LP Filter: Off
P25 Adjust Mode: 14
P25 Adjust Level: 200

Very choppy audio but at least I'm decoding it as non-trunked. I'll need to find or build a directional antenna (yagi, moxon, etc) to follow the control channel and decode better.

I really hate to be the bearer of bad news, but there's precious little you can do to improve reception on a simulcast P25 system - and I'm being generous when I say that. Either you're in a good spot or you aren't - and obviously your spot changes continuously if you're mobile.

Scanners don't have the separate I and Q branches needed to correctly decode LSM.

Yes, I've heard the stories of those people that "fixed" reception one way or the other, but I'll counter with "confirmation bias" - Google it if you need to.

Sorry - I'm a listener myself and I know the pain. But I also don't like to see people putting effort into solutions that just aren't going to pay off.

Is that easy to implement, possibly in Uniden's new scanner?

Just a thought, I don't monitor the system down there but with any simulcast system if your getting "clash" from more than one transmitter maybe you need to eliminate the other transmitter. I'd suggest maybe playing around with your antenna. If you are in a area where you can hear more than one transmitter....try reducing your antenna.

There are tons of variables here. Some spots may hear three or four transmitters, some only two etc. But I generalized it a bit here to make things easy.

In the analog world, you'd listen to sheriff transmitting from Verona. You needed an antenna that's able to hear that one repeater. With the new digital system, you have many transmitters making the need for a large antenna array not necessary. If you reduce your antenna, you may reduce the number of transmitters your hearing which should help eliminate clash.

This is just an idea to try and help some. Your mileage may vary.
