Question about Icom M302 VHF Radio

Icom vhf radio

I have a twin engine outboard boat and when i have my engine off i don't have any issues with my vhf. Once i turn either engine on i get a hum in my vhf speaker. It does not matter what engine is on. Do i have a bad filter in my vhf. I also don't get the hum in my stereo system pulling off the same power source as the vhf. Any ideas?

This is a front end issue that has to be remedied by a radio tech or the factory. The front end is the receiver and it takes special tools and equipment to test and calibrate it correctly,, The only thing you can do is check the ICOM page to see where it can be serviced.

Probably not the squelch but the speaker on the VHF. These radios are famous for crapping out when getting wet.
Try listening to the weather radio VHF ch 01, 02, or 03. depending on your location and play with squelch.. Keep in mind they do make external speakers you can hook up.

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's the channel frequencies for a common 22 channel motorola 2 way vhf radio?

Not sure what you want.....VHF band ius approximatly 130mhz to 175 mhz..... in that VHF band there is a commercial VHF band aprox. 155 mhz to 175...... the amateur radio vhf band is aprox. 135 to 150mhz.

With amateur radio, any freq in that range can be used...... with commercial radio the FCC cangive a company any freq. in that range also.

If you are looking for FRS/GMRS frequencies they are UHF freqs not VHF.

So I'm not sure exactly what you want......sounds like you might want to program in FRS freqs into an Icom amateur radio. If thats the case you will need an Icom that will do UHF freqs.
