NAME
Input terminal for data transmit. (1200 bps: AFSK/9600 bps: G3RUH, GMSK)
GND Common ground for DATA IN, DATA OUT and AF OUT.
PTT terminal for packet operation. Connect to ground to activate the transmitter.
PTT P
When grounded, microphone input (pin 6) of [MIC] connector will be disconnected.
Data out terminal for 1200 bps operation only.
Squelch out terminal. This pin is grounded when the transceiver receives a signal
which opens the squelch.
SQL • To avoid interfering transmissions, connect squelch to the TNC to inhibit transmission
when squelch is open.
• Keep RF gain at a normal level, otherwise a "SQL" signal will not be output.
DESCRIPTION
Regulated 8 V output.
Input/output pin.
(HF/50 MHz only)
Grounded when transmits.
Data line for the optional AT-180.
(*If the modification (p. 140) is
ALC voltage input.
Input/output pin.
(144/430 MHz only)
Grounded when transmits.
AF detector output.
AF Fixed level, regardless of [AF]
position indefault settings.
Squelch output.
Grounded when squelch opens.
