HF Mystery Signals / Data transmission 4.997 to 5.005 MHz

« on: April 02, 2020, 0420 UTC »

Noted on the WOR mailing list by several individuals UTC 2 April 2020 since at least 0110 UTC. A data signal of some kind, about 6 KHz wide, causing a lot of interference to WWV on 5.000 MHz.

Lower edge about 4.997 MHz and upper edge about 5.005 MHz.

It was quite strong at my QTH in upstate NY when checking at 0210 UTC, but is weaker now. Being heard on multiple Kiwi SDRs, with midwestern and eastern receivers getting much stronger signals than in the western US. I could even here it weakly on the U Twente Web SDR   in the Netherlands.

Preliminary TDOA analysis seems to be pinpointing a “hot zone” on an axis from northern Indiana up towards Chicago, and indeed signal levels on individual Kiwis near Indianapolis and Chicago appear to be quite strong.

Software / Carrier Sleuth 1.0.8 expired?

« on: May 01, 2019, 0444 UTC »

I wanted to give Carrier Sleuth a try. I downloaded the latest version, 1.0.8, but when I try to run it, it pops up a message box saying that it is a beta version which has expired. Is there a newer version?

Peskies / UNID Spanish Language 4101 USB 0700 UTC 19 Feb 2018

« on: February 19, 2018, 1609 UTC »

I was hoping to log some SW desert beacons from my NE US QTH, and heard an ongoing net between at least 2 or 3 stations. I have heard many Peskies in the typical 6900-7000 kHz range, but this is the first time I have heard voice traffic on this frequency.

I have heard Peskies a little higher in the 4 MHz range in the past though.

It was unusual in that it was in USB as well. The transmissions were quite faint here. I checked several online KiwiSDR, and found the reception was stronger in the Midwest, and especially strong on Token’s SDR in California, and the Kiwi in Arizona, which leads me to believe they may have been located in Mexico.
