1.2. Receiver data
Sensitivity: AM: S/N better than 10 dB for an input signal of less than
1 µV pd (-107 dBm), 30%, 1kHz modulation, according to
CCITT.
IF selectivity: Less than 6 dB down at +/- 7,5 kHz
More than 80dB down at +/- 20 kHz
AGC: Less than 3 dB audio variation for input signal levels between
2,0 µV and 250 mV pd.
Intermodulation Two interfering signals of equal amplitude and at least 70 dB
more than the desired signal and at a distance of 100 kHz from
the operating frequency will not generate 3rd order
intermodulation products, at the receiver output, larger than the
desired signal.
Squelch: Internally adjustable between 1 µV and 50 µV, selectable
on/off from front panel.
Hysteresis less than 3 dB.
Audio outputs:
Loudspeaker: Max. 1 W, 10 ohm, adjustable by volume
controls.
Line: Adjustable from -20 to + 10 dBm.
Ri = 600 .
Floating transformer with centre tap.
Distortion: Less than 5% with 70% modulation,
100mV RF input signal.
