Frequency 3.515

[mellan]

Does anyone know what what Frequency 3.515 is used for, or where the transmission is from?

 

[Mick]

Amateur radio is in that area, from 3.5 - 4.0 MHz.

3.515 MHz? That's in the Extra class cw segment of the 80 meter ham band.

It would help if you could describe what you heard and where, on this great ball we call Earth, you live.

If it was Morse code, it was a ham and you'd need a call sign to look him up. Some times you'll hear fishing boats off the east coast of N.A., I've even heard them here in the midwest (no, they aren't supposed to be transmitting there). If you heard a broadcaster, it was probably an image in your receiver.

I've even heard them here in the midwest

I'm only a few hours from you and never get to hear anything from the coast. :-(

3.515 MHz is the low end of the 80 meter amateur band, At this low end of the band, you'll hear CW and data (RTTY, PSK, etc). Great at night when the MUF drops off.

Need more info than what you gave homeslice.

Maybe a type of transmission, sounds/ voices you hear, modulation etc...

I heard what seems like a data stream or maybe from a satalite not sure. I heard it at @ 7:30-8:30 EST I live in Bflo, NY . Thanks All for your input.

OK you heard right, the CW ops have been complaining about data too low on the band lately. Can't say what mode it is since I don't tune down that low. That time of the evening it's opening up pretty well along the Eastern Seaboard, to the west as the sun sets across the continent. Nope, no satellite operation above 15M and I think that OSCAR died some years ago.

Hey, the frequency goes down the wavelength goes up and we're talking meters, not megahertz. (;->)
