HF Mystery Signals / HF UNID, 4476KHz center, 1432khz BW from 3760 to 5192KHz, 4khz carrier spacing

« on: August 04, 2022, 1359 UTC »

A very wide discernable signal on the waterfall, with "carriers" every 4Khz.
First carrier at 3760KHz last carrier at 5192Khz
13:46UTC 8/4/22 ongoing
Bursts up to 18 seconds long, some as short as 2 seconds long, the transmissions are occurring no more than 20 seconds apart.

I have a recording taken in IQ mode centered on the first carrier, some screenshots of the waterfall showing the definition of the signal.

Receiver is my own KIWI SDR and 160M inverted V in Ohio.

With an intriguing opening track, it's Redhat.

SDR - Software Defined Radio / KIWI SDR more audio bandwidth now available.

« on: January 30, 2019, 1543 UTC »

While repairing one of the kiwiSDR's I admin I found that the admin can now enable a mode that allows for more reciever bandwidth at the expense of one channel. It looks like this update went live within the last month.

Now one can have up to 20kHZ audio bandwidth up from 12kHz. This does decrease the available receivers down to three.

I have set up websdr.wc8voa.org:8073 to this mode for a while to play around in. I may change it back soon but if I catch wind of an XFM show I will flip it to wide so we can all take in the high-fidelity.

Try it out, take turns!
