The truly portable SEM 52-A first appeared in 1971. A nice little strap-on radio that
was produced in high numbers.
It offers six channels, all crystal controlled, with a total of 26 different
frequencies divided in six different channel plans. For more information on
these rather special crystals and their frequencies, see Crystals.
The SEM 52-A originally was called SEM 52 - for more information see the previous
page - follow the Up link.
The radio uses a rather uncommon fixed headset, to be strapped on to the ear. It
offers good sound and a microphone that actually picks up the sound through bone
conducting. However, though this headset was allegedly developed on advise of
the army, it never was popular with the soldiers. Therefore the SEM 52-A was
rather quickly replaced by the SEM 52-S. A complete radio consists of the
following parts:

At the moment I do not offer too much
information on SEM 52-A yet - however I wanted to share the as far as I know complete list of parts on this web
site, including NSN's and prices.
