Antenna: This is a quarter-wavelength, permanently attached, flex-
ible wire. The ground plane of the circuit serves as an untuned counter-
poise capacitively coupled to the body of the user.
Spurious Emissions: To minimize the production and radiation of
spurious emissions and harmonic energy, and to promote stable opera-
tion, the collector of each
RF stage is separately decoupled from the
9-volt supply by ferrite chokes, resistors, and bypass capacitors. The
base circuits are similarly decoupled except that they use resistor-capac-
itor (
R-C) networks, whose higher-impedance levels are more appropri-
ate.
