General information
2-8 HF SSB Transceiver 9323/9360/9390/9780 Technical Service Manual
Intermodulation
To produce a third order intermodulation product equivalent
to a wanted signal producing 10 dB SINAD, two unwanted
signals greater than 30 kHz removed from the wanted signal
must have a level greater than 82 (80) dB above the wanted
signal
Third order intercept (unaffected by AGC):
+8 (+5) dBm with RF amp off
-2 (-5) dBm with RF amp on
AGC
Less than 2 dB variation in output for input variation between
1.5 (2.5) µV and 100 mV PD
Fast attack, slow release
AF response
Typical: −1 dB 300 Hz to 1 kHz
Typical: −6 dB 1 kHz to 2.6 kHz
AF power and
distortion
2.5 W into 8 Ω, 5% THD
4 W into 4 Ω, 5% THD
7 W into 2 Ω, 5% THD
Clarifier
Nominal: ±0.001%
Clarifier is automatically reset to mid-frequency with channel
change
Inband IMD
Better than 25 dB IMD with two 100 mV PD RF inputs
Signal to noise vs
input signal
An increase of input level of 40 dB above the sensitivity level,
increases the signal to noise at least 35 dB
