Equipment / Re: bigger LOG.....

« on: December 04, 2021, 2221 UTC »

Noise or overload?  Which SDR? Did you try backing down the gain?

AFEDRI-SDR.  Don't think it's overload, it's not blanketing across the whole spectrum (and, if it matters the SDRDX OVL light isn't flashing!).  I have an AM station close so thought that might be the issue but the HPF is working great as I barely see anything under 2.5MHz even with the gain pushed up. If i drop the gain i lose pretty much even broadcast HF signals....

Thought it might be the hot tub since the antenna runs near that (and my heat pump) but shut those off and the noise persists.  Suppose it could be the neighbor's....

here's one of the 'hot spots'....the noise spikes are about 26.5kHz apart.....

Equipment / Re: LOG Not Performing Well

« on: December 04, 2021, 2209 UTC »

I've been using a 8x10m LOG for a few years w/ my AFEDRI-SDR and it's been a decent performer.  It's using 12GA single conductor insulated wire. I do have to pump up the gain all the way on the SDR, however.  I think i'm using a 9:1 balun at the moment.

....aaaaand noise.  Lots and lots of noise.  Put a broadcast HPF on the coax, but that didn't really help .  Tried playing around w/ the gain, and still no joy.  Going to see if it gets better this evening as sometimes there's periodic QRM around the neighborhood.....


This was with the smaller loop...although not this evening.

Getting ready to embark on a great experiment....expanding my current LOG (~8x10m) quite a bit.  Going to run around the house (driveway crossing be damned) for a 35x20m loop. 

Fingers crossed...if it works i'll be able to move my feed line much much closer to the shack in addition to whatever additional benefits a larger antenna might have.....

Now if i can only find my yard staples....

Shortwave Broadcast / WINB? 9265 AM 1724 UTC 27 NOV 2021

« on: November 27, 2021, 1729 UTC »

Very weak, mostly just a carrier on the WF with occasional bits of audio.  Tried doing some searches to see if i could eyeball the antenna and, well....it's interesting if I'm looking at the right thing.  The FCC database wasn't much help....anyone know the story here?

EDIT:  that's the feedline...it goes to a rhombic in a nearby field

Was on a road trip in PA and (moderately) surprised to see WMLK’s antenna still standing….

General Radio Discussion / moderately on topic...no RFI from new humidifier

« on: November 21, 2021, 1827 UTC »

Just purchased a small ultrasonic humidifier for my office since the desert-like humidity levels play havoc with my sinuses.  I was pleasantly surprised that the wall briquette and the device did not hash up my radios....at least the bits of HF, VHF, and UHF I'm currently monitoring. 

That is all!

HF Mystery Signals / Re: UNID 6970 2019 UTC 19 NOV 2021--see waterfall

« on: November 21, 2021, 1448 UTC »

Intriguing….were you receiving directly or via a remote SDR?  I’d think they’d want to have as directional a signal as possible, so it raises the question why either of us would pick up if they’re targeting Europe. I guess I might catch some of the NJ signal, and you the CA-ish signal….

I was wondering about data compression but the only thing they need to transmit is a time stamp, the ticker symbol, and the price info…?

Any ideas...twice these signals appeared simultaneously....

guitar music...way down in the static. SIO 222 if that...

~0115 UTC: 

should point out i grabbed that off Chris's KiwiSDR, not mine...was too weak for me to copy

1351 UTC: maybe REM?  Weak signal at my location.  maybe SIO 243  <-weak signal, some fading, no real interference, easily intelligible. 
1404 UTC: station ID as WREM; signal getting stronger.  S-meter actually twitching from time to time.

Have it loud and clear here in MD as well.  Looking back at the various logs this thing has been chugging along for awhile....
