Marine Radio

There are other frequencies used for various things which are available to the average person trying to decide what they will use for the pre and post Aftermath. For instance, around the coast line of the US (and other countries) the marine radio is used for ship-to-ship and ship-to-shore communications. Every boat larger than 20 feet probably has a radio and many boats like dinghies will usually carry a handheld radio. There are a lot more frequencies on the radio and you can purchase a handheld unit for around $100 USD. There are some limitations. First, it’s illegal to use it “on land” (in the United States) and during the normal, everyday situations that we tend to hope continues for us one and all, we’d not want to use it “illegally”. (Note: While visiting the Bahamas recently I routinely used a marine radio on channel 16 to call for a Taxi). But in an emergency, anything goes. Again, in the Aftermath, it is doubtful anyone will bother enforcing rules. So, the next radio system in consideration for use and easily obtained by anyone in the US is the marine radio[94].

Marine radio frequencies are from about 156.050 to 163.025 MHz. This places the channels in the Very High Frequency band (VHF) and as such these are Line of Sight only. This means to transmit over the horizon (which is only about 3-5 miles usually) you have to be high up, have a high antenna or have a pretty powerful radio (50 watts) which makes the radio non-portable, only “mobile”. Mobile in this case means connected to a car battery system (a car, truck, boat and so on). But, two hand-held radios can talk to one another short distances away. Also, if you’re trying to use such a radio close to the shore line, you’re going to be heard by others with radios. The coast lines are saturated with radios, and that includes the Great Lakes, and anywhere there happens to be a lake. Again, using this radio on land, not associated with talking with another boat is generally not legal to do.

There are 88 channels. This Wikipedia link will give you more information on the channel usage. http://en.wikipedia.org/wiki/Marine_VHF_radio
