011 Four-level scrambled ones. Transmits a scrambled, constant high logic level as a four- level (2B1Q) signal. Feedback polynomial determined by the htur_lfsr control bit. 100 Reserved. 101 Four-level scrambled data. Scrambles and transmits the four-level (2B1Q) sign and magnitude bits from the channel unit transmit interface. Feedback polynomial determined by the htur_lfsr control bit. 110 Two-level unscrambled data. Constantly forces the magnitude bit from the channel unit transmit interface

Push and hold to turn the talk around function ON. • The talk around function equalizes the transmit frequency to the receive frequency for transceiver-to-transceiver communication. WIDE/NARROW KEY . Push to select the IF bandwidth to wide. • The wide passband width can be selected from 25.0 or 20.0 kHz using the CS-F14 CLONING SOFTWARE. (PMR operation only) Ask your de

The amplitude-limited MIC signals are output from pin 5, then applied to the base band IC (IC5, pin 3). The applied MIC signals are amplified at the amplifier (TXA1), and level adjusted at the volume controller (VR1). The level adjusted MIC signals are applied or bypassed the compressor section, pre-emphasis section, TX/RX HPF, de-scrambler, limiter, splatter, in sequence, then applied to another volume controller. The compressor compresses the MIC signals to provide high S/N ratio for receive
