Military Low VHF Skip
« on: February 17, 2023, 1709 UTC »
For a few days now I've been receiving good quality voice skip from Fort Bragg, North Carolina on 38.900 MHz. It's in mil wide FM (+/- 8KHz) with a 150 Hz tone.
They've self identified as Fort Bragg Range Control, mentioned 46.750 MHz as another range frequency and at one point seemed to have conversed with another mil radio station that was far away.

This is a killer list.  Thank you Teotwaki. 

VHF low band has been going absolutely nuts lately.  There have been numerous days where I can hear Fort Hood Range Control on 30.450 MHz every day like clockwork.

Yesterday I heard an open mic (carrier) with the 150 Hz tone on 34.150 MHz....going for at least several hours yesterday afternoon.  At the same time, 30.45 FM was loud and clear!   Here are two videos I got of the 34.15 MHz FM signal:

https://www.youtube.com/watch?v=QbptQoCWlYo

and

https://www.youtube.com/watch?v=N7pF6Z5ixmo



Another one that is military - not US military but military nonetheless, is the Canadian military beacon YSD on 36.600 MHz FM [CSQ].  It is located at the Canadian Forces Base Suffield in Alberta and "YSD" is the identification for CYSD, which is the Suffield Heliport.  That base's air traffic frequencies are listed as 126.200 MHz AM for VHF and 230.500 MHz AM for UHF.  Range control is on 49.900 MHz FM (listed as 49.9 FM). 

The beacon transmits YSD in Morse code, followed by a short tone burst, a second or two delay, and then the ID repeats itself.  Reminds me of a NDB ID in many ways.   I have no idea how much power its running, but I doubt it's a lot.  Probably less than 50 watts.  Maybe less than 20 watts.  The beacon is listed specifically with the Suffield Heliport - but it's smack in the middle of the 30-88 MHz military FM tactical band (and VHF low band in general).   So I'm thinking it could be used for purposes of training "old school" direction finding or homing using VHF FM military radios, or there's another reasoning I'm missing.

Anyway, it's worth checking that frequency when the band is open.  Open your squelch, 36.6 MHz FM mode.  When the signal is nice and strong, it actually sounds better in AM mode, but it's FM. 

Here are some videos I managed to capture of the YSD radio beacon using handheld radios just today:

Looking to see if someone might be able to help me out with a request.  My VHF lowband setup is not what it used to be otherwise I'd do this myself.
I have a restored military vehicle complete with the radios and I'd like to be able to have some military comms running through the speaker when at car shows etc.   I'm planning on wiring up a bluetooth speaker into the existing setup.

Next good band opening for someone, it would be great to have maybe 30 minutes of a mp3/wav file of military comms.   Not picky at all, scanning through the band is fine as long as there's around 30 mins of transmissions.   If anyone can help out, I'd sure appreciate it!
Default RX location is Wisconsin SDR on 135 of wire. Other RX will be noted.
