Two-way 100 BdBaud (unit symbol Bd) is the unit for symbol rate or modulation rate in symbols per second./500 HzHertz (Hz), unit of frequency, defined as one cycle per second (1 Hz). Russian Telegraph system, attributed name VEZHA-S (ВЕЖА-C, Tower-S), usage claimed to be by Russian Ministry of Communications (Минкомсвязь России). Possible usage in meteorology under callsign RWD59. This signal has always been seen transmitted with another identical signal at another frequency, so it works on a two-way communication network. It's periodic transmission behavior is suspected to be ARQAutomatic Repeat reQuestAutomatic Repeat Query between the two users. Reported to be a very old Soviet-era system.
