[DX] Commando Solo, kyllä ja ei
Alla oleva ote on DXLD numerosta 3-077.
Siinä Stig Adolfsson väittää, ettei Afganistanin Information
Radion lähetys jaksolla 8700 tullut milloinkaan lentokoneesta.
Ilmeisesti hän laitteillaan pystyy mittaamaan Doppler efektin,
josta ilmenee onko lähetin paikallaan vai liikkuuko se. Jostain
luin aikoinaan, että 8700 (ennen Bagramin lähetintä) olisi tullut
Turkmenistanista. Ainoa peruste tälle oletukselle, jonka olen
nähnyt, on jonkun sattumoisin kuulema turkmeninkielinen
keskustelunpätkä ko. jaksolla. Onko kellään tarkempia tietoja
mahdollisesta silloisesta lähetinpaikasta?
Stigin mukaan Irakin Information Radion lähetys jaksolla
4500 tulisi tosiaan lentokoneesta.

** IRAQ. 4500, often at 1830, Radio al Maulumat, "Information
radio" heard every day, sometimes disturbed by Russian
SSB-traffic. As you all know by now the program is transmitted
from an airplane, a modified Hercules; on board you will find a
among others a 10 kW SW-transmitter from a very well known
radio company in the USA. I can measure the Doppler effect
when the aeroplane moves. The shift effect is about 4 Hz which
indicates a speed of just above 500 km/h. A month ago she flew
over a small limited area but today they fly almost 20 minutes
on a steady course. The flight area is of course expanded in
the same rate as the underlying terrain has been secured. As a
comparison I will mention the station earlier on 8700 kHz
[Afghanistan]. This station has never transmitted from an
aeroplane enen if some people still claim this (Stig Adolfsson)
11291.9984, Always: This frequency is still covered by a carrier
without information. Has drifted downwards about 0.7 Hz in 5
weeks. From a reliable Finnish source it is claimed that this is
land mobile (vehicle) station with 1 kW output effect (Stig
Adolfsson, Sweden, SW Bulletin May 4, translated by editor
Thomas Nilsson for DXLD)
