All the sets in this series are of tube type design, with the only presence of transistors being in the radio's internal inverter power supply. A removable cover allows access to the sets controls which are placed up one side. The radio is fully operational with this cover in place and it does provide exceptional protection for the controls, as well as further enhancement of the radios water tight integrity. The short antenna supplied with the sets is unique in design and also reminiscent of it's WW-II German ancestry. Releasing this spring tension collapses the antenna allowing it to be rolled up for easy storage and the radio will receive with the antenna collapsed, thus making it harder for enemy snipers to spot the radio operator.
Accessories are available to allow the set to perform various tasks.
Without exception they exhibit the utmost in simplicity, and crude utilitarian design. Carry equipment consist of a very thin plastic covered cushion or a heavy canvas padded cushion, that is placed on the back of the radio, and simple canvas straps. A long sectional antenna is provided to increase the sets range while in it's backpack configuration, it does not incorporate a spring to minimise damage. A metal frame used to secure the radio in it's transit case, can also double as a vehicular mount. Other accessories include a long wire antenna, and a 50 watt mobile amplifier is also known to have been built, both intended to increase the basic radios range.
