The radio had excellent parameters for the times. To reduce dimension
and consumer power so- called transceiver schematic (when the
same parts are used for receiving and transmitting) was used.
So, the radio had weight only 2- kg (or 4 pounds) that was perfect
for ww-II radio. Antennas and spare parts had weight 2- kg (or
4 pounds). Batteries weighted 6- kg (or 13 pounds). The radio
set was packed in two small fabric bags. Figure 1
shows the schematic. Some of the samples of the “Sever” were marked
in English and American or English parts were made for producing
of the stations.
Receiver was made by usual at the times scheme 1-V-1. It had one aperiodic
RF-Amplifier and then a Regenerative stage. Hi-ohmic head set
was used by a radio operator.
Transmitter had output power near 2-Watts. It has RF generator and then
power amplifier. RF generator could work in two modes- first, using external quartz resonator (usual there
were several of them in the radio spare parts), second, in self-excitation mode covered a wide frequencies range. A small key was used for transmitting.
