"EVERYMAN" SHORT WAVER-continued
It must be emphasized that the curves
shown are for an average receiver and are
drawn to give the listener some knowledge of
the wavelengths covered by each position of
the Tank Condenser.
Individual receivers
will vary somewhat, due to different valve
and circuit capacities, and the effect of aerial
load, although minimised in this receiver, will
influence the wavelengths covered to a small
degree.
