This may be an example of the gain possible with a 10-12 km long Rhombic MW
antenna.
1386 khz ~ 341 m (prob only 250 m)
10 km ~ 29 wavelengths

== Kalingrad may have a MW transmitter (with rhombic antenna) that has 26.1
dbi gain ==

Tuning around our MW bands last night around 1900 UTC, I caught the tail end
of a Voice of Russia transmission on 1386 kHz out of Kaliningrad, which was
followed by those familiar trumpets of doom and some ranting preacher
reading text from the book of Revelation. Then the great prophet himself
came on the air saying he had leased time on 1386 "out of Radio Mos-kow".
(...) He also said he was leasing Monte Carlo 702 kHz which was just about
audible at my QTH. He then went into some "talking in tongues" mode which
made constant reference to the "Soviet Union". This guy is predicting the
end of the world, but hasn't grasped what happed in Russia over 14 years
ago!
