Then adjust the TNC mod-ulated signal to a lower level than the voice modulatedsignal.• Read the instructions supplied with your TNC carefullybefore attempting packet operation with the transceiver.• Pin t AF OUT is for 1200 bps operation only. This pincannot be used for 9600 bps operation.• Over modulation may degrade signal quality. If you findthat many transmissions are failing, re-adjust the modu-lation level.SQLPTTRX AUDIOGNDTX AUDIOTNC sideq DATA INw GNDe PTT Pt AF OUTy P SQL
