Type N socket (50Ω) for frequencies over 25MHz only.
Type N socket (50Ω) for all frequencies, including HF.
SMA type socket (50Ω)
External reference clock input of 10MHz (2dBm±2dB). When a valid 10MHz is
entered, it automatically switches to that external input.
Secure the DC cable with this clamp to avoid the DC connector to be pulled out
accidentally.
DC barrel socket (5.5/2.1mm), center positive, for power input. DC10.7V〜16V
(2.0A@12V).
BNC type socket (50Ω)
Outputs analog IF at 45.05MHz with a bandwidth of +/- 7.5MHz.
(Output level is +10dBm relative to antenna input)

12V DC output.
No current limitation. Both voltage and amperage depend on power supply
1
DC input.
Discriminator output
Unfiltered audio limited to the NFM receive mode.

0.78V p-pEMF 10kΩ (NFM deviation 3kHz, audio 1kHz)
External mute input.
Short this terminal to the ground to mute the receiver's audio output.

Remember that this function does not protect the high frequency circuitry
from strong nearby transmissions.
Control 1,2
When busy (squelch is open) the control closes between 1 and 2 terminals.
4,5
Uses non-polar photo MOS relays. Up to 350mA on-resistance 2Ω or less,
load voltage 40V)
6 GPS time pulse input
Low level audio output (2.5mV@600Ω)
7
Not affected by changes in AF GAIN.
