The humble yet capable marine VHF

Although marine VHF radio has been around for a while, it has not only remained useful but is also still a vital part of any vessel’s safety equipment. In fact, VHF units are so capable that many cruisers may not even be aware of all the things they can do. And even with the advent of cellphones, VHFs are still important to any vessel’s communications system.

VHF-based communication came on to the boating scene around the same time FM receivers began showing in up cars back in the ‘60s. This makes sense, as they are both FM radios that have a clearer signal with less static and noise. The drawback to FM radios is that they have a limited range compared to that of the older AM radios. The limited range, however, is more than compensated for by a clear and easily understood signal that is critical in emergency communications.

The USCG does not recommend trying to use a cellphone in place of a VHF radio. In an emergency, a properly installed VHF will not only have a stronger signal but will reach more listeners as well. Being able to broadcast to many listeners at one time will result in faster response in an emergency; a cellphone simply cannot do that.

Like many of the electronic devices we use, VHF radios have improved over the years. Although their basic function remains the same, there have been many added safety features such as digital selective calling (DSC) and automatic identification system (AIS), as well as built-in GPS and the ability to communicate with other onboard electronics. All these new features add a new level of safety and automation to the humble VHF radio.
