  • Page 28: Transmitter Deviation Adjustment

    3.11 SQUELCH ADJUSTMENT The squelch circuit is designed to open or close depending upon the noise content and not the strength of the received signal. Therefore high squelch settings are not necessary nor possible. The squelch on both the VHF and VLO receivers is factory set to open at approximately 22 dB SINAD, while the guard receiver is set to open at 25 dB SINAD.
  • Page 29 6. Key the transmitter and input a +10 dBm (2.5 VRMS), 2.5 kHz audio signal into microphone input 1 if in single mode or microphone input 2 if in dual mode. 7. Adjust the wideband deviation limit potentimeter, R21 on the VLO Rx/Tx module (see Figure 3-6) to produce a ±4.25 kHz deviation.
