Radio Buyer's Guide

Purchasing a portable aviation radio is an important decision, and the options can sometimes be confusing. Every instrument pilot should carry one as a backup, and they can also be invaluable for flight schools, FBOs or just for fun. An important question to ask is how you plan to use the radio-will it be a backup, or will it be used every day as a primary communication radio? The answer to that question will determine what features are important to you. Below, we've described some of the important features and terminology you will encounter when choosing a portable aviation radio. COM vs. NAV/COM: The most basic radios are strictly for communications (COM). However, many radios (NAV/COMs) also offer navigation functions. These radios will receive VOR frequencies and display a course deviation indicator (CDI) with a TO/FROM indicator-just like in an airplane. This feature is a great backup for emergency situations. Localizer: In addition to VOR reception, Sporty's SP-200 NAV/COM also receives localizer frequencies and displays a CDI. In an emergency, this feature allows you to fly very precise approaches to many larger airports, even with no electrical system. Bearing to station: This automatic feature shows you what radial your airplane is on, relative to the selected VOR. Useful for situational awareness, you get an instant reading of your bearing to the VOR. Duplex COM: To reach many Flight Service Stations (FSSs), you must transmit on a COM frequency, but receive on a NAV frequency. This is possible on many hand-held NAV/COMs with the duplex feature. 8.33 KHz spacing: In the US, aviation channels are spaced 25 KHz apart. To reduce frequency congestion, Europe spaces some channels by only 8.33 KHz. This is usually a selectable option on properly equipped radios. Battery type: For backup or emergency use, regular alkaline batteries are the best choice-you don't have to worry about them being run down between uses. However, for everyday use, NiCd, NiMH or LiOn batteries offer the convenience of recharging at the end of each day. NOAA weather: NOAA Weather Radio is a nationwide network of radio stations broadcasting continuous weather information directly from the nearest National Weather Service office. These stations broadcast warnings, watches, forecasts and other hazard information 24 hours a day, 7 days a week. This service is available only in the US
