Yes, Same with many companies at the moment, ELAD are having problems as well. Simon Brown, G4ELI https://www.sdr-radio.com

Dennis KA6FUB - those bursts you're seeing are the USN's ROTHR, with several sites in CONUS and elsewhere. The other, continuous transmission is most likely/certainly on of the "Konteynr" OTHR sites

I wonder what somebody in Greenland or Iceland might see. Greenland might be the closer location to the source if it is East of you and significantly stronger than at Simon's place.

BTW... The SteppIR's place both signals recorded above East of me, and the magnetic loop placed them both at approximate 060 deg. Too bad the Kiwi Sysops have real crappy antennas on their SDR's.

Mike (N2MS), Sure sounds similar, but at 060 degrees with +/-10 of uncertainty, places it in one of the Russian Republics possibly. O60 degree plot from my QTH: Be a BIG bummer when this this appears

Thanks Simon... -- Dennis KA6FUB

Hi Dennis That i think is frequency hoping data.. It also appears on 7mhz..etc.. I cant remember the post and internet pages that went into great depth about that..but it is usa uk etc gov

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
