Input Protection:
30 V RMS (EMF) for up to 15 min.
IF Selectivity:
SSB: 350 Hz to 2.7 kHz
AM: +/- 3 kHz
TLX: +/- 150 Hz (optional)
CW: +/- 150 Hz, +/- 1.20 kHz and +/- 3.00 kHz
(relevant versions only)
Sensitivity:
Antenna input for 10 dB SINAD, 50 ohm an-
tenna.
SSB: 0.6
µ
V
AM: 4
µ
V
TLX: 0.25
µ
V
CW: 0.25
µ
V with +/- 150 Hz bandwidth
When HiSens is selected, the sensitivity is
increased by approx. 5 dB.
Out-of-band Intermodulation:
Two 93 dB
µ
V signals more than 30 kHz off
tune produces less output than an equivalent
input signal of 30 dB
µ
V.
In-band Intermodulation:
Less than -40 dB.
Cross Modulation:
Unwanted signal of 105 dB
µ
V/30%-400Hz
more than 20 kHz offset from receiver fre-
quency, produces cross modulation less than
-30dB relative to wanted signal of 60
dB
µ
V/SSB.
Blocking:
With a wanted signal of 60 dB
µ
V, an unwanted
signal 20 kHz off tune 110 dB
µ
V will affect the
output level by less than 3 dB or cause a
reduction in SINAD of less than 6 dB (SSB).
Reciprocal Mixing:
With a wanted signal giving 20 dB SINAD, an
unwanted signal 20 kHz off tune and 80 dB
above the wanted signal level will cause less
than 6 dB reduction in SINAD (SSB).
Image Rejection:
Greater than 80 dB.
IF Rejection:
Greater than 80 dB.
Spurious Response Rejection:
Greater than 80 dB.
Internally Generated Spurious Signals:
Less than 5 dB SINAD (SSB).
Spurious Emission:
Less than 20 pW/50 ohm at antenna connector
RF-Amplifier:
HiSens selected: Gain 12 dB
HiSens not selected: Gain 0 dB
RF-Attenuator:
Att selected: Attenuation 20 dB
Att not selected: Attenuation 0 dB
Squelch:
Voice controlled squelch.
Line Output :
-10 dBm to +10 dBm, 600 ohm.
Audio Output Power:
Internal speaker: 6 W with less than 10% dis-
tortion.
External speaker: 6 W in 8 ohm with less than
10% distortion.
TRANSMITTER CHARACTERISTICS
Output Power:
250 W PEP into 50 ohm, voice, DSC or ARQ
telex,

250 W CW into 50 ohm for a duty cycle less
than 55% and a modulation rate greater than
3 baud.
Reduction to 100 W when continuously keyed
during 1 min. Automatic full power recovery
after 1 min.
Power Reduction:
Medium: 100 W, 60 W or 20 W (user-pro-
grammable, default 60 W)
Low: approx. 10 W
