If there is power output, you need to use a watt meter and verify that your antenna is good. Depending on the antenna you can also check for a shorted or open connector or cable with an ohm meter.

Hope that helps...

Need a service manual need to modify a MR f55 radio to transmit on 161.600 mhz can you help?

You want to be able to transmit to the Coast Station on this frequency I assume. The Coast Guard monitors channel 16 at all times. This would be the primary channel in the United States. Your radio is VHF Marine Radio and has a built in frequency range of 156.050 MHz to 163.275 MHz. There is no need for a modification. This is a duplex frequency. What that means is you will transmit on one frequency and receive on another, while on channel 20. You will not need to transmit on 161.600. Turn your radio to channel 20. When you transmit, you will transmit on 157.000. And when the Port responds to you your radio will automatically receive their signal on 161.600. So if you are trying to figure out how to communicate with the port authorities then for that frequency turn your radio to channel 20 and you will be able to communicate with them.

Lost Sound

Your speaker has probably failed. I recommend taking your radio to a repair shop to replace the speaker. Should not be an expensive repair. I charge $75 for a speaker repair. They will also be able to go through the radio and check that everything else is ok. Feel free to contact me: if you need any help or want to send the radio to me for the repair.

Transmits but does not Receive

Check your microphone by swapping with another duplicate. If no differance, you will need a SWR meter (standing wave ratio) to find the culprit. It attaches in line of the coax and determinds power out and reflected power. The reading should be 25 watts foward and max of 1 reflected.
