HF (10.127MHz)

[acyddrop]

I was messing about on 10 meters tonight and ran across this signal, I've not heard it before. I'm wondering what it is, I've uploaded it to File Dropper if anyone cares to check it out. On the waterfall display it looks really cool, it might just be a beacon for a nearby airport or something? No clue.

10.127MHz on 10 meters?

10 meters is 28.000 MHz - 29.700 MHz.

10 MHz not 10 meters, it's been a very long day.

The atomic clock in Boulder, CO is close to that on 10 MHz.

That was why I tuned to 10MHz for in the first place, but propagation must be bad because I couldn't hear WWV at all.

75 baud 850 hz shift RTTY

That's been there for years - it's widely assumed to be a USN frequency.

If memory serves, we hams are a secondary user on 30m

IIRC there is no voice/phone on 30 M for HAM

 

[ka3jjz]

Correct - it's all digital or CW

Correct, and you're limited to 200 watts as well.

Thank you very much!
