A: ONLY if you purchase a separate power converter that will convert 24 Volt DC into 12 Volt DC. All Icom mounted VHF and SSB marine radios are designed to operate with 12 V power systems. Connecting them to 24 Volts will result in immediate failure of the radio due to over voltage. It may even damage the radios beyond repair.

Q: My mounted VHF radio, or a SSB radio seems to have a problem. The display lights dim when I transmit. The radio even shuts down by itself sometimes. I'm not getting full TX output power either.

A: This behavior is caused by an insufficient power supply, or bad electrical connection somewhere between the battery (or a power supply) and the transceiver. Check your electrical connections and the battery. Pay special attention to the in-line fuse holders and power cord terminals on the battery side.

Q: Are your waterproof marine radios really waterproof?!

A: Absolutely! But, only to a point. For example, the IC-M15 can withstand being submerged in one meter of water (about 3 feet) for thirty minutes with no water intrusion. If the radio ever goes overboard, you should retrieve it as soon as possible. Remember, even submarines will get crushed if they submerge beyond certain depth. We make quality radios, but we cannot change the laws of physics!

Q: I'm using your optional hailer horn with my Icom marine radio, and all I get is feedback!

A: This is caused by close proximity of the hailer horn to the location of the radio. The hailer horn is VERY loud, and it should be mounted a safe distance away from the operating location.

Q: I have an Icom VHF marine radio, and I'm attempting to contact another VHF operator. But, even though we are very close, we can't seem to be able to communicate. Stranger still, some channels seem to be working, and others do not!

A: Most marine channels can be used for direct ship-to-ship communication. They are called simplex channels. Some marine channels are duplex, and can only be used for ship-to-shore communications. Duplex means that the receive and transmit frequencies are different for one given channel.
