Delco UHF Dispatch

[JRM5204]

Anyone monitoring the new high band dispatch freq (508.2375 PL203.5) and getting an annoying squelch like sound after the tones and voice dispatch for about 30-60 seconds?

You beat me to it...

On Tuesday, I heard the same thing on the UHF channel. I'm wondering if it's possibly data related noise, similar to what happens with the Lehigh County VHF alerting channel (where data is sent after the voice dispatch is put out).

Delco doesn't use that frequency for data. That freq is 154.205. I noticed it start around Friday last week. My suspicion is it's just something interfering. It doesn't go away with the PL set, so whatever it is is probably coming from the county dispatch center.

I had to lock it out, I'm about a mile from the 911 center and the squelch(?) sound was near constant. I keep going back to it to check and its there more than its not.

Same here. Had to lock it out too. I'm going to post a message on the Delco Fire Rescue News board. Most of the end users are on there.

I still use the lowband 46.48 monitoring from South Jersey. {:>D

I think I have only heard 1 dispatch go out on 508.2375 during the time I've had my scanner (about 2 months now). I usually hear all the dispatches county wide on 46.48 lowband. It seems as though the lowband is more reliable than the UHF dispatch.

The UHF is only coming from one tower site right now. You're probably not within range. When I visit my folks down in Ridley, I can receive dispatches on the UHF weak but readable.

Are all dispatches for DelCo broadcast on both the lowband and UHF freqs?

In theory, they should be. The brief period I was monitoring DelCo Fire Board, that appeared to be the case.

On Chester County's dispatch frequency (160.185), there is what sounds like a very short data burst at the end of each transmission. I've asked on here before and no one seems to know what it is either. Not to mention Chester's short two-tone bursts after the actual Quick-Call paging tones and at the conclusion of voice announcements.

The dispatches are actually dispatched on 46.48. 508.2375 is a mirror frequency, meaning they don't actually dispatch on that freq, it just rebroadcasts 46.48.

From what I can tell, they're nothing more than markers signaling the end of a transmission. Chester FB also makes the data burst sound on the East, Central, and West channels.

so how about delco's fire channels can someone break that down for me im mainly intrested in listeing to parkside 45 because we do cover-up there and the companys that border newcastle county delaware. delaware is so much less confusing to monitor i dont see why they need soo many differnt channels

 

[CommJunkie]

New Castle County is a little easier to monitor because everything responds initially on N-TAC 3 and if they switch they do it after already responding.

Delaware County, PA is on a conventional system, though, with a very tough terrain to get decent radio coverage on all frequencies. There are 6 primary fire channels (1, 3, 4, 5, 7, 10) and 2 medical channels. If you want to hear Company 45, they are on Fire 3. If you want to hear the companies that go to New Castle County fairly often (Companies 39, 40, 66) they are all on Fire 5.

What ever the problem was it seems to have gone away. I pick the UHF dispatch up alot better than the VHF Lo and I'm not anywhere near the comm center.

 

[DELCOLHFC]

I agree, it is much clearer now. Sure am glad that darn static is gone. I will ask some questions of my guys that work at the 911 Center, see if they have any info on possible improvements.
