The National Radio Co. started as a toy company in 1916 and was
soon making household appliances. Radio was not part of their
production until the mid '20s when they stared making components.
National became the parent company of the famous
Browning-Drake receivers of the 1920s. By the mid 1930s, they were
well on the way to becoming one of the top manualfactures of
communication & amateur radio equipment.
OFFERED FOR SALE: The above 4
tube, small regenerative UHF receiver (measures just 11 x 8 x 7")
in exceptionally clean and in working condition. The vernier
tuning control tunes the entire coverage of 1 - 11
meters. The power is supplied from a separate (not included) power
supply. Other circuit features are tuned RF and AVC. Six different
coil sets are needed to cover the entire 1 - 11 meters. One coil
set (F) is included, others I do not have.
Speaker and power supply are not included. Speaker requirements
are not critical, anything from 2000 - 7000 ohm impedance will
suffice. Works best with a standard PM speaker with a typical
single ended output transformer as the output connections go
direct to the output tube plate and B+.
Power requirements: filament; 6.3 volts @ 1.6 amps (AC or DC), B+
@ 180 volts nominal. I do not have the power supply but as noted
it can be operated from batteries or a power supply would be a
simple construction project.
