Cobra Mr F75b Marine Vhf Radio Fixed Mount 25watt Questions & Answers
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.
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:
[email protected] if you need any help or want to send the radio to me for the repair.
I have an icom m304marine vhf with a shakespeare
Sound like you have an antenna issue. Try a different antenna with coax. If the problem is still there, than you have a problem with the radio. Icom makes really good marine radios but you could have a defective one.
What is the recommended prop diameter and pitch for a 7.4L King Cobra OMC on a 245 Sundowner
props and made to suit the engine to do a certain job
they are pitched to maintain performance while operating in the torque range of the engine
To that end you have to talk with a marine specialist shop and discuss what you use the boat for, what speeds you want to operate at , operate in salt or fresh water, what loads you wish to carry
There are many pitches and prop sizes and all are engineered for a specific task

Radio transmits at close distance
If the radio device has a variable strength setting for transmission, set it at the higher value... for example 5 watt as opposed to 1 watt. Also, ensure you have a quality antenna. Radio signals are usually line of sight signals, so if there are many obstructions between the radio antenna and the receiver/listener, strength of signal can be affected.
I just bought a new boat and need to buy a boat
Never buy a trailer with the same capacity as the weight of your boat! This can be very dangerous! Instead, make sure the trailer's capacity is at least twice that of the weight of the boat, all your gear, and the boat's motor.
