Informationen:
                                    1 . The RA. 1771 and RA. 1772 are fully synthesized solid
state communications receivers providing reception
facilities for LSB/USB (A3A, A3H, A3J), AM(A3) and CW(A1).
ISB (A3B), FSK(F1) and AFC facilities are provided by
optional, internally fitted, modules. In addition, a manual
RF tuning unit may be fitted.
2. The built-in synthesizer is phase-locked to the output of
a frequency standard, which may be either internal or
external, and covers the frequency range 15kHz to 30MHz
in switched 1MHz bands. In the RA.1771, the kHz setting is
selected by rotary decade switches, with digital indication
in 10Hz increments, while in the RA.1772 the synthesizer is
continuously tunable over each 1MHz band and on electronic
readout indicates the kHz setting to 10Hz. Except for the
method of frequency selection both receivers are designed to
the same specification.
