UZBEKISTAN / ARMENIA
Frequency intermodulations are always enlightening and tell-tale,
not only on Amateur radio BANDWATCH projects.

The use of the intermodulation 11590 kHz frequency
is very enlightening in time slot
13.00 to 13.08 UT from Tashkent UZB only,
S=9 strength of fundamental 11510 kHz.

The parallel transmission from the TAC-UZB location
of 11510 and 11550 kHz FUNDAMENTALS
show Tashkent UZB intermodulations on 11470 and 11590 kHz.

Suddenly 11590 kHz covered from 13.08 UT onwards on a much stronger
fundamental Yerevan Gavar Armenia outlet of S=9+30dB,
empty carrier started til 13.11 UT,
latter then when TWR South Asia interval signal started til 13.15 UT.
