Pin - Signal Name
h - WIDE BAND AUDIO IN
This input is the single ended wide band audio input. It has a nominal impedance
between 2k Ohms and 5k Ohms and a 3 dB bandwidth of 1 Hz to 27.5 kHz. The
input is adjustable from .1 Vrms to 1.5 Vrms and set to .6 Vrms.
i - GUARD AUDIO INHIBIT
When this input is pulled to ground, the guard receiver audio is disabled.
j - AUDIO HI OUT
This is the high side differential audio output. It can drive a 150 Ohm load to 100
mW and a 600 Ohm load to 25 mW. 3 dB bandwidth is 300 Hz to 3 kHz.
k - AUDIO LO OUT
This is the low side differential audio output. It can drive a 150 Ohm load to 100
mW and a 600 Ohm load to 25 mW. 3 dB bandwidth is 300 Hz to 3 kHz.
m - AUDIO GND
This ground is for shielding the audio outputs.
n - EXTRA WB MAIN RX AUDIO
This output is the single ended extra wide band audio output. It is capable of
driving a 2k Ohm impedance and has a 3 dB bandwidth of 1 Hz to 40 kHz. The
output is adjustable from .1 Vrms to 1.5 Vrms and set to .6 Vrms.
p - MAIN SQUELCH DISABLE
When this input is pulled to ground, the main squelch conditions are overridden.
q - WIDE BAND MN RX AUDIO OUT
This output is the single ended audio output. It is capable of driving a 2k Ohm
impedance and has a bandwidth of 1 Hz to 27.5 kHz.
r - DF ENABLE
Grounding this input enables the DF audio output. DF function only available
when using the main receiver. Digital channels do not have DF capability.
s - DF AUDIO
This output produces an output proportional to the AM signal. The output has a 3
dB bandwidth of 1Hz to 10 kHz. The output will drive a 2k Ohm impedance. The
output is adjustable from. 1 Vrms to 1.5 Vrms and set to .1.4 Vrms (4Vp-p).
