Huh? / Re: I hate Whisper ham radio

"Don't hate the mode; hate the software"

WSPR is useful for trying out antenna changes and for checking out propagation paths. Having said, I do find it to be a drag that so many kiwi SDR channels are taken up with daemons.

Maybe after Halloween we can chase all the demons (and daemons) away....

OMG. Someone needs to tell me how it comes out. Does the earth survive? Does humanity survive?

I her some weak music via the K1VL SDR in Vermont, USA at 0002 UTC. I can't tell what type of music but there is something there.

I have only heard a dead carrier. Do you have an ID?

A little birdie told me that - whatever it is - seems to be coming from the southeast US or thereabouts.

It's interesting because this is approximately the same frequency as that Link-11 transmission that has been there for years, every night, but has been absent for the past few nights. That particular transmitter has been TDoA'ed to roughly the Florida east coast, just as the little birdie told me just now.

Hmmm... I bet this is a US military transmitter gone haywire, possibly the same one that transmits the Link-11, and it is creating IMD (intermodulation distortion) products at 6830 and 5714 Khz (and probably other places) too.

EDIT - Whoops, the Link-11 is on ~6943 now too. Oh well, there goes that theory.

IT'S THE WAR OF THE WORLDS!

Seriously, this is similar, I agree.

Bits of maybe kinda-sorta music.

The "distributed" frequency nature (showing up on multiple frequencies at once) makes me think that someone has a very severe Intermodulation Distortion (IMD) issue.

I'm going to check if 6830 is // 6945. --> Conclusion: They do seem to be sort of doing the same thing.

Off or stopped at 0021 UTC but only briefly.

Amazingly, I'm in here before Danger Kitty.  ;D

S9+10 on the K1VL SDR in Vermont.

Sound effects with a lot of reverb or feedback and occasional audio cut outs. There is no "intelligence" being conveyed, no music or speech - other than that used as a base for the reverb.

No, I don't think it's a digital UTE.

Is someone is experimenting with their new sound effects box?
Is Zeke on the mushrooms again?
On the other hand - the cutting out is making me think that someone is trying to play music and turned all their knobs up to eleven. All of them at the same time. And playing themselves back from an SDR for reverb. Doing this by accident. (Or maybe intentionally.)

I used to listen to a lot of experimental music stuff with a lot of effects and no commercial potential. At least that stuff had some sort of rhythm.

Bottom line: I don't know.

Stopped at 0028 UTC but for how long? Back at 0029.

North American Shortwave Pirate / Re: 6200 kHz. testing again
« on: October 17, 2023, 2251 UTC »
Class E is wholly inappropriate for a modulator. He will be unable to make it not sound unrecognizably horribly distorted. Class E is not intended for audio amplification. No one uses Class E for audio for this reason. I assume he means Class D, which is widely used for audio and is appropriate.

I want to be encouraging and not haughty but I have been casually watching what he has been been doing and I'm going to suggest that at his level of skill and knowledge that building a Class-D amp is a bit beyond even slightly uncomfortable reach for him. I'm doing one now for myself and there are numerous potential pitfalls, just as there are in RF design. Recognizing those pitfalls ahead of time and coming up with solutions to the pitfalls that you didn't catch requires a certain depth and experience. I suggest buying a regular Class-D audio amp and using it instead. At his TX power level, they are completely appropriate. They are very inexpensive and bound to be a lot less frustrating for a beginning experimenter. Many of us on here, including me, have done this for various projects to save a lot of work and time.

Audio is a bit rough and distorted on both microphone and music. Sounding a lot like RF getting into the audio: https://voca.ro/13ru0MiiwcQV

Otherwise S5/SINPO 45444 on N1NTE SDR in MA.

Says something else briefly, then...

He said, "I guess it's working" or "I guess this is working." Then immediately off the air.

About 3 hertz up from the frequency where KRAP was. Interesting coincidence.  :D

89
KRAP, not at all sounding like crap.  ;) Very nice 11 KHz, well modulated audio. Nice stuff on the N1NTE SDR.

0030: The Vogues, Five O'clock World
0032: John Fogerty, Rockin' All Over the World
0037: Sign off announcement, with 75m AM lingo about "The pubes in the transmitter". Into Suzie Quattro.
0041: PA off, but driver is still on? Still a carrier about 10-15 dB below what it was.
0044: Male and female spoken speech.
0046: Ozzie accented. Must be a different station but almost the same frequency as KRAP, about 3 Hz up.
