I think this is the same seen here (Southern OR USA). -- Dennis KA6FUB

Some type of HF Radar? Check the "29B6 Kontaynet OTH Radar" at this site: https://www.sigidwiki.com/wiki/Category:HF Mike N2MS

Here are two recordings, you will notice via the untrained ear that they sound slightly different (baud rate?). The signal is continuous for +10 minutes at a time. Not a short burst. Firing up the

Does anyone know where we can get the Arinst SDR Dreamkit V1D? The Ebay site is out of stock <https://www.ebay.com/itm/234169277921> Supply chain issues?

Correction. It seems to be spread over the 18MHz maritime band. I am also hearing it on the 16MHz maritime band. Mike N2MS

It seems to be spread over the 10MHz maritime band. I am also hearing it on the 16MHz maritime band. Mike N2MS

Kriss, Are you refering to that pulse signal that lasts for about a second? I noticed it yesterday while monitoring 10 meters. I am hearing it this morning on 18445, 18465, 18486 and

The SteppIR's confirm it's East of my location in NH. I pulled out my active magnetic loop antenna and it appears to be emanating from ~060 degrees. I could hear it on Simon's server at an S9, but not

Will send you a few DLLs. Simon Brown, G4ELI https://www.sdr-radio.com

Like Mag loop Simon I find such on all HF bands - seems to follow the MUF and propagation. Has recently been 100kHz wide centered on 28.0MHz. They seem to avoid the heavily populated FT8

Simon, have you received you’s? Mine came the other day. Pretty quick delivery from Russia to US (20 days). It’s a pretty cool little receiver and works better than expected. I have updated to

It’s not local, it appears for an hour or so in the AM and is heard on my server network both here at my QTH (KA1GJU Super Stations #1-4) and 13 miles away at our local radio clubhouse

If you have not tried killing your main power or one breaker at a time then it would be worthwhile. I fought interference for a few years and finally tracked it down to a cordless phone charger in

Hi Thats everywhere.. 160-17 maybe higher. Some just stays there 24/7 some randomly changes frequency.. Thoughts are.).been discussed here i think) A over horizon radar B new commercial data for

I tried the Kiwi SDR TDoa, but it appears very few have decent antennas attached. The plot would give widely different locations with every run. Time to hike up to shop and do an A/B test with the

Anybody got a direction of the source of QRM on 17m in the AM here in USA? My beams are fixed due to the tower tops occupied with VHF/UHF repeater antennas. I usually operate in the upper portion of

Hi, FWIW I’m going to run some tests with my server to see if I can deliberately force this problem. Simon Brown, G4ELI https://www.sdr-radio.com

Gl;ad that you found the source of the log on. I'm off in a couple of weeks to a KU (actually Kansas State) football game and thought that I might drop by there and knock on doors for you. Looks

Don, Thank you for the information. The examples here: https://www.rtl-sdr.com/kiwisdr-tdoa-direction-finding-now-freely-available-for-public-use/ appear to indicate that the KIWISDR does a decent

Well the KIWI TDOA location feature can do very well for locating HF transmitter sites.
