More importantly, Tim, they used TDoA (time difference of arrival)
KiwiSDRswhich have time-stamped data secured from our GPS system and
drewequal-time hyperbolic lines/curves which would eventually intersect at a
"source"
Note the location that was indicated, and, on more than one occasion duringthe
time this was under study: a location in the US, in Pennsylvania, not tofar
from an educational institution.

Scroll to the last page – they used webSDRs to find it.
It is fixed now. 9 AM this morning someone shut it down. Came from central
Pennsylvania.
Was broadband 3.850 to 3.905 MHz
