VHF low band has been going nuts the past weeks.
This afternoon I was tuning around and on 36.6000 FM - 36.600 MHz FM I heard a Morse ID “YSD” followed by a long tone burst. Sounded like a VOR or aircraft navigation beacon like a NDB. 36.600MHz YSD Radio Beacon - 36.6 YSD Beacon CYSD CFB Suffield Heliport, Alberta Canada at Canadian Forces Base Suffield. This is a first for me.
1872 miles (3013 km) from receiver location in Richmond Virginia, USA.
Transmitter coordinates GPS lat/long
N50°16.00' / W111°11.00'
50.276359,-111.180189
I wanted to post this here in case other folks come across this recorded CW and tone on 36.600 MHz FM while tuning around the bands. It as a Morse recording on a FM signal, not AM like most VHF aircraft beacons…also the frequency choice is within the military 30-88 MHz band, which makes sense for that application (and makes sense for it to be in FM mode).
