What would be on 165.1125 ?

[fuzzymoto]

I posted a few days ago in the PA forum with no responses.

Does anyone have any idea what the frequency 165.1125 would be? It seems to be some sort of race control for a Triathalon and also a Fire Police frequency--I heard both on the same day organizing traffic control for some sort of race. Maybe this is a perfectly normal use of the frequency but I've simply never heard anything in the 165 range being used before and it seems odd. I find no record of it anywhere other than being in the military/government ranges. Anyone have any idea what this would be?

that section of the band is US GOVERNMENT AGENCIES usually. A lot of military installations operate in the 163 to 174mHz range. GOOGLE 165.1125 and you'll see what I'm talking about. Just about every URL it brings up has something to do with Military.

Now I've seen other agencies like DEA/FBI/USC in that range too. USC has a repeater here on 169.4500 mhz.

Your best bet may be to use Google and try to find out what race took place in your area on the date you heard the comms. Then look for any agencies involved with it, especially federal. It may be some kind of Dept of Transportation or something, but I've usually found freqs in that range to be Customs, which definately doesn't sound like what you copied. I'm assuming you're sure you didn't pick up an image, right? No way it's actually your local PD?

I actually have found the race (Pocono Marathon)

But it still doesn't help with what exactly that frequency is. The lead and follow cars were calling out mile markers and the Fire Police units were opening and closing intersections. It doesn't appear to be a military even though all of the google's turn up a military or government organizations using that freq.

Another possibility....

It could be UNLICENSED.. Meaning, It could be a group or organization who bought used radio gear from something like a DRMO auction or by other means, with that frequency loaded in it, and they're just using the radios. I've seen that happen on contruction sites. Someone gets ahold of a bunch of old portable radios at an auction or something that still has channel information loaded in, and the people just start using them without even thinking. Next thing you know, they're talking on a police freq.

 

[fuzzymoto]

I guess it could be...I'm still confused how the local fire police would have ended up on such a freq...but perhaps the organizers handed them radios too.

In a 2001 Scanner Frequency Directory by Daryll Symington, 14th Edition, for NW Ohio, and SE Michigan, they show 165.112 for Selfridge Air National Guard base in Mt. Clemens, Michigan. I don't think they use that frequency anymore. Maybe the guys in your area picked up some older military radios on ebaY and are using them without a license.

? Image of a HAM freq?

Race Starts at Tobyhanna. That is on of the largests electronics repair centers for the military. Maybe some volunteers from the base, or even some radios that got sold to locals as was suggested. Either way, an interesting find.

I thought of that too. I know my old scanners used to be 21.7 off, that would put the transmitted freq at 143.4125, Just under the hamband, and I don't think you'd see anyone actually using a narrow freq on 2 meters.

I had heard some traffic on the frequency earlier (weeks ago) and had it marked as "Military?" with a loud tone so I'd look if it stopped there again. It seemed to me the previous traffic, although brief sounded like something airport related or airport security related. When they started talking about the lead and follow cars I thought I had a military or government motorcade...until they mentioned the runners. They were clearly calling the positions of the lead and follow car by mile marker and the remainder of the traffic was "Fire Police # 1 to Fire Police # 3...now opening the 611 intersection...". At one point someone called to a fire police unit that did not answer and another voice broke in saying he needed to use the repeater to get that unit. It all sounded very official like a county frequency or some sort of tactical channel. I think the Tobyhanna angle may be something. In any case I'll keep listening for more traffic.

I'm not sure I understand the Ham image stuff but it is a new scanner, not an old scanner. (BR330T)

Could it be because this is affiliated with the Red Cross that this would have osmething to do with the freq. choice???

He's using a BR330T (corrected) , which I believe is triple conversion. My knowledge of how to compute birdies is lacking, but I suspect this rules out Ham image.

Actually it's a BR330T

Birdies and images aren't the same thing, but the image is +/- twice the first IF frequency from the actual signal frequency. With first IFs in the 300-400 MHz range, the image would be way out of the range that the front end would accept unless the receiver was very close to the transmitter. In any event, in this case the actual frequency wouldn't be in any ham band.

Monroe county is about 60 miles away from me so we can rule out being close.

My local air national guard used to use that freq. (165.1125), but no longer does. It is still a fairly common freq. for ang units.

 

[fuzzymoto]

Could be....I guess race control could have borrowed ANG radios and loaned them to the Fire Police for the event.

Or for that matter, the local NG unit may have been volunteers to help coordinate. I see the Red Cross was the point of contact for volunteers so ...

 

[fuzzymoto]

Very odd....I'll keep listening to see what pops up on that freq in the future. It actually seemed like it was a Fire Police freq to me but who knows.

Interesting find in any case.

Wow -- this thread is old. Just read it and remembered listening to Letterkenny Army Depot years ago right around that freq. Think there was one or two between 165 and 166. Not sure what your location is or if it's related, but I do remember that. Probably almost ten years ago.
