SDR - Software Defined Radio / RTLSDR based scanner for P25

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.

Occasional bursts of music (piano, flute, etc) and noise pops on freq.  Good clear signal, max S4 or so.

1533: off air

Equipment / Antenna phaser?
« on: October 09, 2018, 0217 UTC »
Are there only three antenna phasers on the market (quantum, MFJ, and DXE)?  The latter is waaaay too pricey, and the quantum apparently is only good up to 2000kHz....which leaves the MFJ box, and I know a lot of folks arenít fans of their equipment.

Was thinking about adding a second LOG and using it as an array with the first one...
