383.550?

[datainmotion]

Getting this one pretty strong here in Thornton (4 bars on Pro-197 / 2 bars on PSR-500). Sounds like telemetry or some type of control channel (no matches here). Has anyone else heard this or know what it is?

I can hear it in Colorado Springs too. It is an unusual sound.

Hearing it here in Arvada loud and clear. Maybe Abqscan knows? Sounds weird.

As this is inside the 380-390 Mhz band, parts of which are being used for military P25 trunks, I'm wondering if this is a control channel or a digital voice channel?...best regards..Mike

Somewhere along the front range, garage doors have started going up and down by themselves...:lol::lol:

As soon as I remember what the darn password is for my FTP, I'll upload a 30 second audio clip.
It sounds analog and the Pro-197 is indicating FM, but no P25...

Using my digital RS scanner searching the aircraft band once i got to that freqency i hit the mode key and it gets louder on the FM then AM and no change on au mode. ET maybe calling home..

383.550 MHz Audio clip

 

[mancow]

Sound similar to the old Russian 150 mhz nav sats.

 

[rckydenver]

Well this freq went silent, nothing.

 

[datainmotion]

Same here.
I sent the sample to KB9UKD's Digital Modes page for the heck of it...

 

[rckydenver]

Same here.

Glad you captured the audio clip. Help figure out this mystery.

It's been suggested to me that it may have been a TACAMO transmission...will have to research that a bit I guess.

I sent the clip to a long time Milcom listener, and he agrees that it probably came from the E-6B that was in the area.

So, you're saying there was one flying over the front range?

 

[abqscan]

Yes, that is what I am saying. Next time anyone hears the data stream, point your browser over to planefinder.net - Real Time Live Air Traffic Flight Radar and with some luck, you should be able to track down the E-6B!

 

[rckydenver]

Thanks Erik!! Had to look up what a E-6B was, now i know, gotta like the wiki..

Silly me...questioning the guy with the ADS-B receiver.
