Set the value to a moderate audio output level. The default value of 4 is approximately 0.5 Vp-p, which is a standard modulating signal. The settings of 0 ~ 9 vary from approximately 0 Vp-p to 1.2 Vp-p. • Impedance: Approx. 10 k. GND Ground PSQ Transceiver squelch control • Connect to the squelch input of the TNC, MCP, or PC connection interface. • Squelch open: Low impedance • Squelch closed: High impedance NC No connection NC No connection GND Ground PKS PTT input for data communication • Connect to the PTT output of the TNC, MCP, or PC connection interface. • Microphone audio input mutes when transmitting. NC No connection Audio input for data communication • Connect to the audio output of the TNC, MCP, or PC (or PC interface connection). • Audio input level is independent from the microphone gain (set ANI with the [MIC] key). • Audio input level can be changed by adjusting the value in Menu No. 73. The default value of 4 is approximately 10 mVrms, which is a standard modulating signal. The settings of 0 ~ 9 vary from approximately no modulation to approximately 1 mVrms. • Impedance: Approx. 10 k. GND Ground PTT input (same as the front panel MIC connector) SS • During transmission, the audio input of ACC2 connector terminal 11 (ANI) and the USB terminal are muted.
