What is it?
no ID just a solid BEEP then that silly tune. ill record it again stand by
28.175 VE3TEN C OTTAWA # 10W, GP
Usually they ID at intervals.
It does sound like some sort of telemetry.
This is from the VE3TEN beacon site:
The OARC's 10 m beacon VE3TEN is located a few miles south of Ottawa, near the intersection of Century Road and Hwy. 416. Current equipment consists of a rack mount box containing the transmitter and power supply, a separate rack box with the identifier unit and a Ringo Ranger antenna mounted approximately 50 feet above ground level. The output of the transmitter has been turned back to 11-12 watts and a ducted cooling system has been made to increase the life span of the radio. The beacon operates on 28.175 Mhz and the mode is frequency shift keying. This means that the radio is on at full output at all times but that the transmit frequency is varied by about 700 hz to provide an audio tone shift at the receiver. FSK can be received by a receiver in any mode.
Note that the transmitter is on 100% of the time. this is why I think the steady tone is carrier leakage.
DE = This is
VE3TEN = Call sign; Canadian
FN25 = Maidenhead grid square for location
Googling VE3TEN provides all the information you need. I didn't try looking in the QRZ database, but the call's probably in there.
Not telemetry, not a "silly tune", just Morse code sent with a slight frequency offset from the carrier in FSK mode.
I didn't upload a video just a sounds file. Lol

Eh, that's what I meant. When I listened before I just skipped ahead to the middle and heard solid tone and then skipped forward and heard warble tones. I'll listen to the whole thing later.
Were gonna be hearing a lot more different stuff now that conditions are improving.
