Numbers Station Phenomena: New Antenna in the World


I live across the street from the Federal Building which houses,
among other things, the NSA and the Secret Service. We can't
park or pull up in front of our building; the space is guarded.
On the roof of our building are older television antennas, as
well as satellite dishes, etc. I attached a 1970s radio kite
antenna wire to one of the stranger antennas, similar to a
vertical wave ground-plane configuration - I'm not sure what
it's four. The wire is attached to one of the 'spokes,' runs
about forty feet through a window frame. The results have been
amazing; the antenna connects to a Sony ICF-6700W shortwave
radio, which is a top of the line 1980s analog model; without
digital noise, the sound quality is great. Even though
short-wave station numbers are on the decline, there were
signals from everywhere, including Turkey and Albania; there
were also a number of anomalous signals, including some unusual
numbers stations at 9330 and 9065 mhz, 3:30 am - 3:40 am local
time. (The whole area of the band was filled with anomalous
transmissions.) The signals are largely a combination of digital
and analog technologies, lookup codes and encoded digital
transmissions. The Spanish-speaking female voice is similar to
what I've heard in the past, as is the five-digit spoken code,
but the intervals are different. A spectrum image is included
below.
