Cross-modulation rejection 95 dB or greater (reference 30 dB SINAD and degraded by 10 dB) in
the presence of a 30% modulated unwanted signal spaced at 200 kHz
from the channel frequency.
105 dB or greater (reference 30 dB SINAD and degraded by 10 dB) in
the presence of a 30% modulated unwanted signal spaced at 3 MHz.
Spurious signal suppression 90 dB, or greater (reference 12 dB SINAD) for a 30% modulated
unwanted signal spaced by more than two channels from the tune
frequency up to 1 GHz, 80 dB or greater for frequencies up to 2 GHz
and 70 dB or greater for frequencies above 2 GHz..
Interfering signals At least 6 dB SINAD is achieved for a wanted -87 dBm signal
modulated with a 1 kHz tone 30% in the presence of two -5 dBm
interfering signals, both FM modulated, one with a 19 kHz tone
7.5 kHz deviation at 107.9 MHz and varied by ±4 kHz the other with a
19.1 kHz tone 7.5 kHz deviation with its frequency chosen such that
one of the 3
rd
order products is located on the chosen receive
frequency.
Antenna radiation
Radiation at the antenna socket is less than -81 dBm, typically less
than -100 dBm, within the frequency range 9 kHz to 4 GHz.
Maximum RF Input
The transceiver can withstand an RF input of +36 dBm for 20 seconds,
and a continuous +27 dBM input, without causing damage.
Transceiver Tx Modulation Characteristics
The transceiver Tx modulation characteristics are as follows:
Mode
AM-Voice mode The AM-Voice mode uses Double Side Band (DSB) Amplitude
Modulation (AM) full carrier, emission designator 6K80A3EJN for
25 kHz channels and 5K00A3EJN for 8.33 kHz channels.
AM-MSK The AM MSK mode uses Double Side Band (DSB) Amplitude
Modulation (AM) full carrier, emission designator 13K0A2DJN.
Modulation Depth
The transceiver is capable of modulation depths up to 95%.
Hum and Noise
The hum and noise is more than 45 dB below the signal level for line
input levels <-13 dBm, and more than 50 dB below the signal level for
line input levels ≥−13 dBm, for a carrier modulated by a 1 kHz signal
with a modulation depth of 90%.
