      R-105 D
R-105 M





  R-105m, R-108m, and R-109m

are optically and technicallly alike, differ only by frequency range. They follow R-105 D to R-109 D, (where metal housings and tubes were used); the M-series uses plastic housings and has soldered sub-micro tubes, printed circuits and is partly transistorized.
The M-series is built in two variants:
1)The indicating instrument is in the center (see picture above)
2)The indicating instrument is in the uper left corner:


R-105 M (R-108m, R-109 M) is a portable and a mobile backpack. Operating mode is F3, simplex. It can be operated by remote control and used at relay operation.
It co-operates with R-107, R-111, R-123; of course also with R-105d, R-108d and R-109d.
