While Dieterle’s crew rejected FRS radios and their voice-activated capacity, we think there is ample reason to keep them in mind — especially if your team is just exploring the waters for wireless communications. We tested Midland’s X-Talker Two Way Radios Model (T77a; $99.99 per pair) with voice-activated capacity and earpieces with boom mics. These inexpensive radios have a long line-of-sight range that can exceed 30 miles. Should you actually want to talk privately boat to boat, they offer 36 channels; each of the first 22 can be encrypted with one of 121 different privacy codes, making 2,662 coded combinations. If privacy is your thing, changing codes after leaving port makes eavesdropping unlikely. They come with Li-ion battery packs, but each can use three AAA batteries instead.
