Technical Details KK "Восток" for 2011 book

[Kyra]

Dear Friends and Colleagues,

In preparation of the 50th anniversary of the flight of Yu. A. Gagarin, I am preparing a technical manual that compiles all known data from the internet and publications that have been published to date regarding the spacecraft "Vostok". (By extrapolation spacecraft "Voskhod" data is also usefull).

Here are some areas in which information is still needed in more detail:

Система электропитания (СЭП) - the batteries seem to be СЦС –5  - but how many are there and how are they configured ? Which voltages were used before the standard of 27 +/- 3V ?

What were the commands used by the CRL Командная радиолиния "МРВ-ВС – БКРЛ-В" ? Does anyone have pictures of the МРВ-ВС panel ?

Three years later the transparencies of the signal tablo on instrument panel the still have not been resolved....we have Спуск-I Спуск-II Спуск-III in green, and the "Sounds Off" and "Emegency Tranferred" in Amber.
Does anyone have any new photos of the PD "приборной доски" from museums ? The panel at the Central Armed Forces Museum can be usefull if one takes a photo with a newer camera in high resolution.

What were the frequencies of the "Tral-P" ? What data parameters were transmitted - a complete list would be usefull.

Thanks for any help!
