Loading...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.
