Radiom-77

On the 25th of July a variant of the squeaky wheels iconic marker was found being used by radiom-77 is it unusual that the station was assumed to be on much lower power during this period.

Picture of Radiom-77 operating on its backup frequency due to multiple jamming's on the 24th of July. The marker sounds like a variant of the early 2000's buzzer with what seems to be the auxiliary transmitter active due to 50hz being present.

"Radiom-77" is the former callsign of the Russian Military station that operates on 4728,4823,4679 and 7036kHz. The stations was first discovered on the late 2018 on the frequency of 7020kHz with is disappearing completely around December that year and it reappearing out of nowhere July 2026.

The most prominent feature of the station first going on air after many years was It's terrible transmitter, and frequent marker changes. Specifically frequency breakdowns, multiple voice cut outs during voice messages and the marker jumping in frequency and generally being unstable. Around September and August the station almost entirely stopped operating on 4728kHz and moved to 4823. At the time of the frequency changing, 4823kHz was close many other Rus Mil stations such as "FENT" on 4840 and another station which does not use primary callsign on 4828.

Full list of sender callsigns for the previously 4828 (now 7020) station :Облако47, Флаг31, Основа98. Translated to English: Cloud47, Flag31, Osnova98.

Around October time, Radiom-77 adopted the callsign IKShP and moved to 7036kHz as well as FENT and the (formerly) Oblako-47. It is not exactly known but it is assumed the Radiom-77 AKA IKShP is located in near St, Petersburg in the Nizhniy region of the Novgorod Oblast.

Transmitter information: little info of the transmitter equipment is known apart from the updated and more stable transmitter adopted around September to October time. The antenna is most likely and end fed halfwave or five element Yagi.

There is also less marker variation with the station uses various remakes of the 4625kHz buzzer or a generic 320Hz pip style marker.

Voice traffic: Voice traffic is primarily test counts and 4 figure Uzor messages but what is most noticeable is the sudden increase of voice traffic when a Military Training is in progress as well as a suspected CW Morse code variant of the station being present on various frequencies but mostly around 7030kHz.
