[Scan-DC] Greenbelt DORIS coordinates

[Andrew Clegg]

I am using GNU Radio Companion for the USRPs, on Raspberry Pi. Not really optimized for scanner-type stuff, but it's extremely flexible and intuitive for experimentation. It has a very large user base of academics and industry types.

When you get close to the actual site, the signal is overwhelming on
both frequencies.  It is on the east side of Springfield Rd.   If you
see the sign that say "Experimental Antenna Range"  south of there
directing one to a road going west off Springfield, that passes by the
Goddard Amateur radio club.   The Goddard SFC NASA HF station (I  heard
in SSB working other NASA locations during Y2K issue) might be
co-located (I am not sure).

It sounded identical to me with the HackRF 1.  I am still trying to see
if I can figure out the data I copied but it takes time.

Most of the dongle stop at 1.7 or so GHz with a few going to 2 GHz.

I have a USRP clone but never tried getting it working.   What software
do you use with your USRP?
