Yesterday I received a Radio Rossii program on 1215 kHz. This frequency is not listed in the WRTH or MWLIST but it used to be in use by Radio Transmitting Centre 5 in Kaliningrad.
Mr. Andrey Molokov confirmed my report in a day with a f/d eQSL which indeed suggests it was the Kaliningrad RTC5 that was active with 150 kW. Mr. Molokov acts as QSL manager and can be reached via andrey_hamradio[at]mail.ru .
