Suite à ma réception DRM de R.MAYAK j'ai reçu une eQSL de Oleg UA3ARI pour ces émissions tests qui sont effectuées depuis l'Université Technique de Moscou, voici les détails donnés par Oleg sur ces TESTS:
Hello,
It was short (a few days) test transmission on 25900 kHz at Moscow within the framework of local SFN research.
We used 2 transmitters:
1 - 500 W, 100 m antenna height, Kurkinskoe shosse;
2 - 100 W, 35 m antenna height, Aviamotornaya st (Moscow Technical University of Communication and Informatics).
Both antennas was 5/8 CB, tuned to 25900. Transmitters was linear with modulators from RF-Mondial.
Audio content and label was "Radio Mayak", mode A, 10, 18 and 20 kHz.
"Radio Mayak" is standard test signal for all RTRN research in Russia, and at
newsmayak@radiomayak.ru do not know when and where his signal is used in the test transmission.
I confirm that this transmission was carried out on 25900 from Moscow with low power in February 2013.
We did not expect that stable long-range reception may be possible therefore not inform in advance.
Transmission on 25900 are finished.
Thank you all for observation!
Oleg
