This simple set for headphone use is housed in a small polished mahogany
It bears the 'Gecophone' logo on the front of the set
and the "Entirely British Manufacture" BBC
transfer on the
back of the set.
Connection points for the aerial, earth, optional coil,
glass enclosed galena detector and headphones
are provided, and the controls comprise a tuning knob
and a lever to adjust the cat's whisker.
Tuning uses a variable condenser. Turning the knob will change the resonant
frequency of the tuned circuit. A separate coil could be
used for the reception of long wave. Two people could
listen to the radio at the same time. Two antenna lengths
and "B" (medium) can be used.
The set would have
cost 16s in 1926; an extra 7s 6d for a 1600 m long wave
