Need to communicate in a “dead spot”?

You know what I mean…..that cell phone sits there next to you (sometimes for hours) and doesn’t do anything.  Then you suddenly remember something that you had to tell someone and you don’t have any signal!  UGH!  Now, wouldn’t it be nice if the person you were calling had a VHF (very high frequency) radio?   Then you could call him/her on your hand held VHF marine radio (assuming you’re within approx 20 miles) and your call will go through since it doesn’t rely on cell phone towers.  These type of radios have been very effective for even farmers since they have better penetrating powers and can be easily used in any type of terrain.  One main drawback does exist with the VHF Radios.  In spite of the fact that they seem to have the ability to clearly broadcast voice messages for the longest distances, the broadcasts can be terminated if you find yourself with a large obstacle such as a tall building or a high hill between you and the person you wish to speak to.  This is because the broadcast signals travel in straight lines.  Even with this drawback they have been proven to be very useful in even the day-to-day operation of many businesses.  These radios (if equipped with a single side band) even have the ability to transmit digital data from one computer to another.  The world we knew is changing rapidly.  Let’s enjoy the new technology!  Happy Boater.
