LF: Mystery signal "VVV TEST"

["James Moritz" <james.moritz@btopenworld.com>]

Dear LF Group,

I have been trying to D/F the "VVV TEST" signal on 500.5kHz for the past few
days. The SNR here has not been good enough to get an accurate null using
the loop antenna, but the bearing is definitely roughly NE/SW from my
location at IO91VR just north of London. The signal has DX-like QSB so I
guess it is at least hundreds of km from here. In the light of other
reports, a location somewhere around the Baltic area, or perhaps beyond,
would seem feasible.

Cheers, Jim Moritz
