154.370 D351 Kerchunks

Post by Scott »

Anyone have any idea what this might be? I'm guessing Cape Cod/SE Mass by the signal strength I'm seeing in SDR#. Kerchunks every 7 seconds or so lasting about 3 seconds. I have not observed this before today and the bands do not seem to be open. I could be missing it but nothing in the Wiki, Logbook, NEFD, or at RR that matches up with the DCS tone.

I am getting this full strength at my house.
There is a tone each time it transmits.

I am thinking it has to do with the new license for Seekonk fire, or something else in town.

EDIT: Also remember that Seekonk PD use D351. (Which is a very common DPL in Bristol County. Used in Attleboro, Norton, etc).

This is a new dual-mode repeater with encryption, most likely in Seekonk, based on some radio traffic I heard this afternoon.

154.3700 P25 NAC 508 was mostly used for radio traffic. I also had a couple of occasional hits with encryption here too
154.3700 NFM D351 was used by "radio service" for testing as well.

The only positive location given was someone was "at lunch at Wendy's" (Which is on Route 6 on the East Providence line).

Of course many remember that this was the old, long time Providence Fire primary frequency. Providence still has the frequency licensed as well.
(However the license was modified simplex only, as an "intercity" channel, with 154.2800, which is the normal VHF intercity used in Rhode Island).

So every day this week (Mon, Tue & Wed) radio service has been testing with someone, maybe dispatch at various locations in town. Monday they tested both analog {154.3700 Rptr D-351} and P25, but Tuesday & Wednesday radio tests all day were P25 only {154.3700 Rptr P25 NAC $508}.

The FCC license claims it's for the fire dept. Anyone have any thoughts why Seekonk Fire would be using VHF? I only ask because Fire District 3 (Bristol Cnty) is mostly UHF users (fire & police) and the Fire District 3 mutual-aid channels are solely UHF. Unless the police are looking to switch off UHF to VHF now? We won't know until it's in use full time. TBD..

I remember when Providence launched on RISCON that there were questions about whether the FD would entertain a simulcast on 154.37 and the no answer was qualified by the statement that they had already brokered a sale of the VHF equipment to a local fire department. This was over a decade ago, but could Seekonk have purchased the equipment with an agreement that Providence maintained the license until they were ready to use it? The equipment was probably EOL at the time, but the frequency could have been advantagoeus for some reason.

Thanks Ed. Will keep an ear on it some more. It's obviously a mixed mode repeater, as I mentioned in my first post.

While most everything surrounding them is UHF or trunked, they could still end up going VHF.
As you know recently Seekonk did approve the money to upgrade the radio systems. And the PD/FD intercity ops for Rhode Island are VHF, but no one else is.
So we'll have to see.

(Seekonk is surrounded by East Providence [RISCON], Pawtucket [UHF], Attleboro [UHF], Rehoboth [MSP Trunked], and Swansea [UHF].)
(*And while Barrington shares a border, there are no direct roads between the two).

154.3700 D205 is having some repeater troubles and the CWID keeps half transmitting, the muting. What I have got out of it is "WRFR"
Which is a good thing, because Seekonk's license for this frequency is WRFR795

This D205, is the same as D351 and NAC 508h, as the same radio testing last year appeared on all three.

Now to identify WHAT it actually is, aside from a malfunctioning repeater

I'm hearing that here as well. Sounds like WRF to me, a brief pause, and then 3 dits that don't sound like CW, for lack of a better explanation. Then a squelch tail of a few seconds, and it drops. Roughly 5 second break and then it repeats.

Could be the WOW signal?

Yeah, that's it. Sometimes all it gets out is a "W", and one time it got to WRFR, but never got any further than that. Something is definitely FuBar.

Mike and Scott,

I looked into the licensing and the fire frequency 483.450 has been renewed under a different license with a 6/2029 expiration. I don't see a renewal on the 470.8125 police frequency that expires in 2025. They have the two new channels 154.37 and 460.200 they expire 6/2028. Maybe one of these are going to be the new police channels. They are going to open the microwave system soon I would think if the new tower is completed. I'll keep an ear on those new frequencies. :pint:

FYI, 154.3700 D205 with the full CWID. WRFR795

It's police use. Exactly what, I don't know.

They're escorting to the "main gate", which I assume is Seekonk Speedway.
