Power consumption:
ac dc
Transmit 330 VA 10 A
Receive 70 VA 1.4 A
Standby 45 VA 0.5 A
Supply ac: 99 to 264 V 48 to 62 Hz

RECEIVE RF
Sensitivity -107 dBm for 10 dB (S+N)/N
Selectivity:
8.33 kHz <6 dB at ±3.5 kHz
>70 dB at ±8.33 kHz
>80 dB at ±25 kHz
25 kHz <6 dB at ±11 kHz
>80 dB at ±25 kHz
Squelch Threshold adjustable in 1 dB steps
for RF input levels from –114 dBm
to –60 dBm (<6 to >30 dB (S+N)/N).
Incorporates Digital Coherent Mute
(DCM) technology to dynamically
filter on-channel interference. DCM
automatically mitigates co-location
interference to ensure the squelch
opens whenever an input
signal exceeds the set threshold
and has a positive (S+N)/N ratio
AGC RF <3 dB change in audio output for
RF signals between –107 dBm
and +10 dBm
AGC audio <1 dB change in audio output for
modulation depth change between
90% and 30%. Automatically
maintains audio at the 90%
modulation equivalent level for
maximum fidelity
Antenna radiation <-73 dBm
TRANSMIT RF
Carrier power 5 to 50 W in 1 W steps
Modulation 0 to 100% in 1% steps
VSWR mismatch Full power into VSWR of 2.5:1
Infinite VSWR without damage
Harmonic outputs <-36 dBm
Spurious outputs <-46 dBm
VOGAD <10% change in modulation depth
for 30 dB change in input level
Tx mute 5 dB below VOGAD threshold
Time out Off, or 2 s to 510 s in 2 s steps
AUDIO CHARACTERISTICS
Audio distortion <5% THD
Audio bandwidth:
8.33 kHz 350 Hz to 2500 Hz
25 kHz 300 Hz to 3400 Hz
Audio interface:
Line output -30 dBm to +10 dBm in 1 dB steps
