Re: 2 way radio preference
Maximum input power on the larger Motorola FMS/GMRS units is 2 watts. If you are looking for consumer-grade GMRS radios, the ones with the maximum input power are the 14-mile ones from Midland (5 watts). Even then, the manufacturer claims as to range are wildly optimistic. Increasing power in GMRS radios does not increase the range linearly, as you increase the power, the amount of improvement you get decreases. <br /><br />For the most parts, the consumer grade GMRS radios won't work with repeaters. The only exception I'm aware of is the Motorola 7100. If you want to take advantage of a repeater, you need to use commercial-grade radios that will cost you over $200 each. <br /><br />Private parties using marine VHF radios for land communications between them in the US is illegal. <br /><br />Keep in mind that unless you are only using the FRS frequencies that have a maximum power output of 500mW (channels 8-14), use of GMRS radios in the US technically requires that at least 1 of the parties in the communication posess a valid license from the FCC. Even that is only true if the other party is an "immediate family member".<br /><br />This would also explain in part Charlie's performance problems...if he were using Channel 12 he would be limited to 500mW power input in compliance with the restrictions places on FRS. <br /><br />BTW: Motorola doesn't make their branded GMRS radios. They're actually manfactured by a company named Giant International, which from memory is headquartered in Georgia.
