HF Beacons / New Beacon "L" 4096.150
« on: April 14, 2023, 0340 UTC »
I was looking at the spectrum around 4096 and spotted a strong (new to me) signal. It sends L about every 7 seconds.

Thanks to whoever built and deployed this beacon!

VHF/UHF Logs, including satellites and radiosondes / Military Low VHF Skip
« on: February 17, 2023, 1709 UTC »
For a few days now I've been receiving good quality voice skip from Fort Bragg, North Carolina on 38.900 MHz. It's in mil wide FM (+/- 8KHz) with a 150 Hz tone.
They've self identified as Fort Bragg Range Control, mentioned 46.750 MHz as another range frequency and at one point seemed to have conversed with another mil radio station that was far away.

HF Beacons / MOVED: All right, fess up! :-)
« on: January 25, 2023, 1401 UTC »
This topic has been moved to General Radio Discussion.
It's funny, but belongs in a general discussion area as it could relate to all solar powered pirate radio equipment

VHF/UHF Logs, including satellites and radiosondes / Frequency Hopping ( UHF SatCom?)
« on: December 06, 2022, 1921 UTC »
I started performing a spectrum survey to get an idea of what UHF SatCom transponders are in view to the SE here and ran across 243.785 to 243.8450 with what looks like frequency hopping.

Rough heading of SE from my location in Orange County, Calif

Anyone have info or ideas?

HF Mystery Signals / Unknown 40 meter signal group
« on: November 20, 2022, 1505 UTC »
I started out hearing what I thought was some sort of single frequency fast dasher beacon here at home

1.  7900 to 8020 - (kHz)
2.  1450 (UTC)
3.  ongoing
4.  CW
5.  Orange County, CA
6.  Narrow fast pulses

Looking at the KFS Omni I see this thing blanketing the spectrum with parallel signals above and below 8 MHz.

Radar?

HF Beacons / 4098.85 ?
« on: October 17, 2022, 1556 UTC »
Listening on KPH I can hear some weak dits and dahs but unable to discern if there is a pattern or if it's random junk
15:56 UTC 17 Oct

HF Beacons / 4094.8 dasher with mushy Morse ID "SFI"
« on: June 24, 2022, 1345 UTC »
Slow dasher sends 8 slow dashes then what sounds like SFI twice.

Great signal into KFS SE kiwi!

SDR - Software Defined Radio / kiwi software glitches or just problems at KFS?
« on: May 04, 2022, 1537 UTC »
I've already sent an email to the KFS folks but no response.

On my iPhone and on my laptop's Chrome & Firefox browsers I've been seeing the same issue: After going to the main quad kiwi page at
http://kiwisdr1.kfsdr.org:81/

I have experienced the following:

selecting any of the four kiwis brings up a page that has a blank frequency box and even though I type in a frequency and hit return nothing happens on Chrome and on IOS it reloads to display the "Play" arrow icon in the middle of the screen. The screen also does not populate my ID in the name/callsign box as it used to.

The problem seems to come and go. I noticed that it seemed to have started after their domain was remapped but maybe it is due to a recent software release. The ham radio page at http://websdr1.kfsdr.com:8901/ seems to function normally for me.

I don't want to send more emails to the KFS crew unless I can provide something useful so I thought I'd see if this is only something I have experienced or if it is more widespread.

Thanks!

HF Beacons / 4099.90 KHz new beacon or...?
« on: April 30, 2022, 1540 UTC »
On the KPH SDR I ran across this signal but it faded out before I was sure what the slow Morse Code was saying

HF Beacons / 4107.8 slow dasher

Very strong on KFS SE with a roughly 2 sec on and 7 off pattern

Utility / 4108 KHz Morse Code station
« on: March 16, 2022, 1421 UTC »
It is weak here on the west coast and I tried a few SDRs in other areas but no clear signal yet. Just enough to think it is a repeating message.

Is this a previously logged maritime station? I've performed a few Google searches but not had any leads as of yet.

SDR - Software Defined Radio / KFS omni kiwi sdr "Masking" USAF global HF Frequency??
« on: March 11, 2022, 0216 UTC »
Tried tuning in 11,175 KHz yesterday and I could see activity on the waterfall but no audio. Then I noticed this tag


So what sort of feature is this on the SDR and what is it normally used for? It was not applied to other global HF frequencies.

Thanks!
