[amsat-bb] Tranzit-B telemetry system on ISS

[andy thomas]

I've just come across the following interesting references on space ref to what seems to be a VHF telemetry channel (bio/medical monitoring?)

"...including VHF/voice & biomedical electrode belt and *telemetry hookups via the BSS (later by the wireless in-suit Tranzit-B radio telemetry system) for vital signs and equipment monitoring".

and:

" [The suited run requires wireless Tranzit-B suit radio telemetry on both semisets (activated: 2:56am) and temporary deactivation of the Russian VHF channel 1 (Very High Frequency, Russian: UKV1, for ultra-shortwave) to avoid interference from extraneous radio stations to the Orlans while over Russian ground stations (RGS, DO 3/4).  All EVA preps were monitored by the ground via audio, the reason for the early morning time of the training run.  Tranzit-B TM was turned off at ~3:10am EST.]"

My questions are: what is the TRANZIT-B TM system,  how close is it to the 2m channels, what is the TLM data modulation and breakdown?
