Anyone know if the St Clair Ahores PD is still on the Eastern Wayne Consortium tower? Haven’t heard them for a few days.

It’s more than that. All of the SCS calls were coming off of that tower. Now they are not, Looks like they have added a couple of new 700MHz frequencies. Will try adding them.

There were some new antenna sites scheduled to go live in Macomb/St. Clair Counties in early October. No further details as I'm not at liberty to disclose/discuss them.

They are probably on the SERESA Law talk group. I don’t listen to them, but I’m almost sure that is where you will find them.

SCS PD

Yes. Been monitoring them for months on Serena via the eastern Wayne system because i can’t monitor on The macomb county simulcast sytem due to local interference. For the last few days I am unable to monitor them. Something has changed.

If a radio doesn’t affiliate there you won’t hear any traffic period. Not much more about it unless your device doesn’t pick up 700.

Not roaming

Thank you that makes more sense than just an affiliation issue. I can’t monitor the Macomb County Simulcast system where I live due to commercial 800 MHz traffic on a tower located in Brys Park that interferes with the Macomb system. Hopefully Macomb County System goes to 700 MHz some day, won’t hold my breath.

Able to receive SCS PD off of the Detroit system. Not exactly full quieting as local commercial RF (200 yards away) still has negative impact on my reception. All in all, the Detroit system offers slightly improved SCS PD reception over the Macomb County simulcast system. Might try RF attenuation to pad down adjacent channel interference.

Have you tried the Mt. Clemens site to see if that works at all?

Perceived benefit?

Well if I am receiving adjacent channel interference from a commercial tower near 8 1/2 mile and Harper (Brys Park) then I would hope that changing from 800 MHz to 700 would make a difference. Yes have a spectrum analyzer know what I am talking about. Yes have used antenution from 1 to 10 dB to pad down the interfering problem. The adjacent desense is active on almost all of the frequencies arriving from the Macomb Simulcast tower near 10 Mile and Harper. The frequencies used by the CEW are not negativity impacted at my location. Everything worked fine while SCS roamed off the CEW site. Due to site loading SCS SERESA) had to terminate terminate their transmissions at CEW. But thanks for asking.

What is the frequency of the interfering signal?

Macomb County Simulcast issue

I live near St Joan of Arc and have always had problems picking up Macomb County Towers. Recently I was tweaking and I manually added NAC numbers to site on SDS100. Seems like it woke up Macomb County reception. Site NAC = 79B.

Wouldn't really help.

When we say "going 700" what that means is we add additional capacity at the sites in the form of 700 channels. The sites then become "mixed" 7-800 and the subscribers that are 700 capable *can* be assigned those resources. Having said that, we are already "700" Seeing as it's typically a couple of add on channels, your problem would still be there most transmissions.

Just an FYI...
