Not Shaquille, but RadioShack. In 1994, RadioShack proposed a replacement for CB, called Family Radio Service (FRS). It moved things to an ultra high frequency (UHF) band around 467 MHz to avoid some of the interference, and made some other technical improvements like using frequency modulation instead of amplitude modulation that is more noise resistant (but we won’t get into that here). Suffice it to say it’s more advanced, with improvements including the ability to implement privacy codes for filtering out unwanted chatter from other users on the same frequency. Remember the party factoid above on antennas? Well, with 467 MHz, you only need an antenna about 6 inches long to equal the quarter wave-length antenna that was 9 feet with CB. A more sophisticated cousin to FRS is the General Mobile Radio Service (GMRS). GMRS is also a UHF technology and sandwiches its channels within the same frequency bands used by FRS. Many radios these days are combo FRS/GMRS units with channels 1-7 shared between FRS/GMRS, channels 8 – 14 FRS only, and channels 14 – 22 GMRS only—but you don’t need to worry about it, just dial the channel you want and use it. FRS radios were meant primarily for walkie-talkies, have a max power output of 1⁄2 watt and must have an attached antenna. You also don’t need a license for FRS. GMRS, on the other hand, can have a remotely-mounted longer antenna to extend the range, can broadcast at much higher wattage, and requires purchasing a license from the FCC ($85 every 5 years). The FCC has proposed to drop this licensing requirement since they suspect that the vast majority of people purchasing their GMRS walkie-talkies at the local sporting goods store fail to send in the fee anyway. The proposal is pending but expected to be adopted. Meanwhile, read the fine print of any unit you buy; if you are dialing up a GMRS channel today, you need a license.
