                                    The model FR-101 is a solid-state communications receiver
designed to provide extreme flexibility that even the most
demanding amateur desires with provisions tor all mode
reception on twenty one 500 KHz amateur and major shortwave
broadcast bands from 160 through 2 meters. The versatile
FR-101 receiver is capable of transceive or independent
receive and transmit function with the matching FL-101
transmitter or FT-101E 277K transceiver.

New, solid-state technology, with features such as a
double-balanced mixer, offer unparalleled performance and
rejection of cross-modulation and intermodulation
interference. All circuits are composed of standard,
computor type, plug-in modules, for reliable operation and
service* simplicity. A linear tuning, temperature
compensated VFO with 1 KHz frequency readability is
incorporated. A 100 KHz/25 KHz crystal calibrator is
built-in. The FR-101 also includes fast attack/slow release
AGC for SSB or AM and fast release for CW. If desired, the
AGC can be completely disabled. A built-in noise blanker
with adjustable threshold control provides excellent
elimination of most impulse type noise.

In addition to external VFO operation, a crystal oscillator
is built-in for crystal-control operation of 4 channels of
fixed frequency reception. The FR-101 includes a
self-contained AC power supply - adjustable from
100/110/117/200/220/234 volt AC when the primary power
transformer winding is appropriately wired.

The SP-101PB/277PB phone-patch and external speaker
combination is a useful accessory for amateur operatio
