Just slightly above noise level with occasional fades upward. Not strong enough to ID music.

For Sale / Wanted / Barter / SOLD: Cross Country Wireless HF 5 Port Multicoupler 50 kHz - 35 MHz
« on: December 15, 2020, 2112 UTC »
Item has been sold.


FS: Cross Country Wireless HF 5 Port Multicoupler 50 kHz - 35 MHz

Probably 4 hours of use. It was purchased to attach all my KiwiSDRs to the same antenna. Since it is an active multicoupler and I have a really good antenna/location I didn't need the amplication and went with a passive multicoupler instead.

Price new is $175. Asking $135 shipped to US addresses.

HF Mystery Signals / 11m Oddity
« on: November 03, 2020, 1258 UTC »
Recently found an odd signal that appears to be local on 11 meters. It started out around 27130 kHz and drifted in frequency up to 27185 kHz (CB channel 19)



It had constant signal strength of S7 and had a consistent pattern of 10 short and 4 long transmissions:



Then the waveforms started to change a day or two later:



Today, it is down 6-9 dB and the waveforms changed again... sometimes skipping the original 10 short 4 long pattern:




Since I am located in a fairly rural area with no commercial manufacturing or industry it makes this mystery even stranger. I often see the typical "fish hooks" during band openings -  https://www.hfunderground.com/board/index.php?topic=54650.0 - but these are not exactly like that but may be related. (??)

As of the time of this post it was still active if you'd like to see it yourself. Ideas are welcomed as to what this could be.

General Radio Discussion / ΣSDR Expansion - more user slots!
« on: September 23, 2020, 2234 UTC »
A big thank you to Dave, W1EUJ, for offering his KiwiSDR receiver to be set up at my location for everyone to share. It will be connected to the same antenna as the other two receivers so performance on all of them will be identical. This should help quite a bit as both of the original receivers often fill up in the evenings.
