Canadian military airport CYSD radio beacon, transmits "Y S D" in Morse code followed by a tone burst. Similar format to a NDB or VOR type station. No tone (does not have the usual 150 Hz tone squelch that military FM systems usually have - that usually decodes as 151.4 Hz instead of 150.0 Hz).
It's FM, but comes in great in AM mode as well since its just modulated CW. I believe its a 1000Hz tone, but I could be wrong.
I haven't heard it in many many months. 36.600 MHz is the frequency. Strong FM deviation. 36.6MHz CYSD beacon YSD beacon 36600.0 kHz FM
