HF Mystery Signals / UNID pips ~ 14220kHz 1337 UTC 7 June 2019
« on: June 08, 2019, 1806 UTC »
These came up at multiple frequencies (although I don't recall if they were concurrent) on the morning of 7 June.  Interesting thing is the train on a frequency would cycle up in magnitude and back down again....maybe a directional antenna sweeping around?

SDR - Software Defined Radio / RTLSDR based scanner for P25
« on: January 15, 2019, 0239 UTC »
Ran across this tutorial, and it worked very well for getting a somewhat operational (still working on audio issues!) scanner going based on a rtl-sdr stick and a Raspberry Pi...

HF Mystery Signals / UNID 9000 kHz 1914 UTC 11 Jan 2019
« on: January 11, 2019, 2017 UTC »
Maybe our 8000kHz carrier moved to a new frequency?  -87dBm here, started around 1914 UTC 11 Jan.  The spectrogram looks very similar. TDoA is all over the place, but seems to converge in the midatlantic area somewhere.

HF Mystery Signals / UNID 8000 kHz 1434 UTC 10 Jan 2019 signal
« on: January 11, 2019, 0202 UTC »
Strong carrier (-85 dBm at my location currently); about 3Hz wide; might be LSB?.  Has been on since at least 1434 UTC 10 Jan.  TDoA during the day (~2000 UTC) suggests possibly two transmitters...one east coast, one midwest.
