Information
The Icom IC-201 Transceiver for 2m Band is a precision built
high performance Transceiver providing SSB (USB and LSB),
FM and CW modes of operation with an output power of 10 watts.
This is an extremely durable Transceiver which has state of
the art devices such as integrated circuits, field effect
transistors, varactor and zener diodes engineered into a
tight knit straight forward electronic design throughout
both Transmitter and Receiver Reliability, low current
demand, compactness and ease of operation are the net result.
The dual conversion Receiver with its FET front end and
high-Q helical resonators boasts low noise and sensitivity
of — 6dB//*V or less. Audio reproduction is of an unusually
high order of distortion free clarity. High stability is
obtained by using permeability-tuned VFO and double tuning
system (50KHz or 16KHz/T). The HC-attenuator is highly
effective for crossmodulation interference.
The IC-201 FM and SSB modes have individual filters. Other
features include tone control, marker for caliblation 0,
500, 1000KHZ, wide band linear Amplifier VOX, Break-in
circuit, CW monitor, dual power supplies (DC 13.8V and AC
117V or 220V) and an ingenious final PA transistor
protection device, APC (automatic protection circuit) is
also incorporated in the final output circuitry. Should
difficulties occur, (high SWR, ANT mismatch) the APC
instantaneously disables the final PA.
All circuitry is constructed in a series of modules which
are easily removable for servicing. The modules are housed
in a sturdy plated brass frame, which is in turn housed in a
rigid metal case, providing an extremely durable and rugged
unit. Test points are brought up from all major circuits to
facilitate maintenance checks and trouble shooting should
the neccessity arise.
A modern styled face plate, easy-to-read meters, and
convenient controls with specialized design complete the
unit’s styling. The IC-201 is a welcome addition to any
fixed station or automobile.
