What to do if my Raymarine Transceiver has no transmission (TX)?
If your Raymarine Transceiver isn't transmitting, verify the PTT switch's functionality. Also, check Q13, the power transmit circuit components Q1, Q2, and Q3, and the VCO circuit for any defects. Finally, confirm the PLL control voltage reads 2±0.2V at 156.05MHz.
How to fix Raymarine Transceiver that is not able to turn on?
If your Raymarine Transceiver unit doesn't turn on, check the power voltage and the power switch. You should also check if regulator IC8 is defective.
What to do if my Raymarine Transceiver has no receiver (RX)?
If your Raymarine Transceiver has no receiver (RX), check to see if IC11 or IC7 audio output at pin 9 is defective. Also, check Q12, the 21.4MHz output of first mixer Q10, the 21.4MHz output of crystal filters F1, F2, and the 21.4MHz output of first IF amplifier Q11. Check the 450kHz signal from ceramic filter F3, the VCO circuit, and the MCU.
How to troubleshoot poor or no modulation on Raymarine Transceiver?
If you're experiencing poor or no modulation on your Raymarine Transceiver, check the microphone and MIC jack for defects. Also, inspect IC205 and its associated components for any issues.
Why does my Raymarine Transceiver have low receiver sensitivity?
If your Raymarine Transceiver has low receiver sensitivity, check the antenna connection. Also, check the output from Q9, Q10, Q11 and F1, F2 for any defects.
What to do if the squelch circuit in my Raymarine Transceiver is inoperative?
If the squelch circuit on your Raymarine Transceiver is inoperative, check VR203 and IC4 to see if they are defective.
What to do if my Raymarine Transceiver has no sound with AF signal applied to pin 6 of IC6?
If there's no sound when an AF signal is applied to pin 6 of IC6 on your Raymarine Transceiver, check IC1 and its associated components for defects. Also, check the speaker on control circuit VR201, IC10A, and IC10B for defects.
How to fix deviation of transmit frequency of Raymarine Transceiver?
To correct a deviation in transmit frequency on your Raymarine Transceiver, check the frequency of the 20.950MHz crystal X2. Additionally, adjust VC2 and verify the transmit frequency.
