Shortwave Broadcast / Re: UNID 17460 AM 1753 UTC 18 Mar 2023

Thanks! That explains why I wasn't able to ID the language - Kurdish isn't something I'd ever recognize.

I'm not sure what I'm hearing here - any ideas? I can't even identify the language. Google turns up no hits for broadcasters on this frequency, just Russian military.

HF Beacons / Re: Mixed CW / FSK beacon(?) on 4095.38

Very cool, thanks! I thought the FSK shift seemed weirdly narrow.

OK, I think I got all excited about nothing. I've tried a bunch of KiwiSDRs and the signal is roughly equally weak all up and down the east coast. It's much stronger in Europe - I got a great signal in Finland. I'd still love to know what it is, but it's probably not a beacon.

HF Beacons / Mixed CW / FSK beacon(?) on 4095.38
« on: February 27, 2023, 0241 UTC »
I'm not sure if this is a beacon or something else, but I'm hearing a faint signal on and around 4095.38 that transmits CW for a while, then switches to FSK for a bit, then some silence, and repeat. It's too faint and my CW skills are too crappy for me to decode what's being transmitted. Anyone know what this is?

Latin American Pirate / Radio Casa? 8000 AM 0156 UTC 13 FEB 2023

Very faint. Can just make out that the song being played is Every Little Thing She Does is Magic by The Police.

Latin American Pirate / AD149 Radio 6934.9 AM 0012 UTC 10 FEB 2023
« on: February 10, 2023, 0013 UTC »
Frequency is more like 6934.9. S4 - S5, I can hear music but I don't recognize the song.

8
I'm hearing it here as well - gave me a good laugh!

9
Very weak here, can make out that there's music playing but can't really hear much else. S5, but a lot of that is local QRM.

10
Hearing it here as well, but just barely. Rapid fading, signal is about S4 or so.

11
S6 - S7 here, minimal fading.

"Infected Mushroom Head Radio International. Stop interfering with Zee-kee or you will be eliminated." HA! I don't know what I just stepped into the middle of, but it's entertaining.

HF Mystery Signals / Re: FSK signals around 27359 USB 1701 UTC

Interesting idea. Somewhere I have an old wireless keyboard that also worked on 27 MHz. These signals sounded too slow and had too long of a preamble to be keyboard presses, I think. I suspect 45.45 or 50 baud. They also were the same, relatively short, length, which wouldn't be likely to be a mouse.

I tried to make an IQ recording but the signals kept getting weaker and falling into the noise (or the stronger stations, assuming more than one station, were listening at those times).

Oh, right, I completely forgot to do that! You know, the thing I love most about HF Underground is the helpful and friendly users.

HF Mystery Signals / FSK signals around 27359 USB 1701 UTC
« on: November 05, 2022, 1703 UTC »
I'm hearing FSK data bursts on 27359 USB. There are others on 27355 USB as well. WTF? I'm in the US and this is a CB radio frequency - FSK data is generally not allowed. I know sometimes CB channel 23 has some FSK paging signals (I hear them all the time at my QTH) but they're nothing like this.
