Desensitization
Wanted signal 20 µV EMF (-87 dBm), m = 30%/1,000 Hz,
at RX frequency, for S+N/N ≥ 6 dB, in the presence of
Unwanted signal A 10 mV EMF (-33 dBm/50 Ω),
unmodulated, frequency 108 ... 156 MHz, except used CH,
but includes ≥ 1 RX CH, or
Unwanted signal B 200 mV EMF (-7 dBm/50 Ω); minimum
10 mV EMF (-87 dBm), unmodulated, frequency 50 kHz –
1,215 MHz, except 87.5 MHz ... 156 MHz, or
Unwanted signal C 250 mV EMF (-5 dBm), unmodulated,
frequency 87.5 ... 107.9 MHz
Receiver Spurious Emission
≤ 400 pW / -64 dBm (50 kHz ... 1,215 MHz)
Channel Selection Time
≤ 0.4 sec, AF level within 3 dB, max. 99 Channel memories
Receiver Muting, Squelch (CLIMAX)
Simultaneous input at RX frequency:
a) Wanted Signal A: 10 µV EMF (-93 dBm) +8 kHz (m =
30%/1,000 Hz), Squelch is open.
b) Unwanted Signal B: More than 24 µV EMF (-85 dBm),
m = 30% / 1,000 Hz, vary this frequency slowly from -8
kHz to +4 kHz. Squelch must remain open.
