Josh: Hadn't thought of your question in that way. Amateur radio operators traditionally refer to a band by wavelength instead of frequency. 160 Meters is 1.8 MHz 80 Meters is 3.5 MHz 40 Meters is 7 MHz 30 Meters is 10.1 MHz 20 Meters is 14 MHz 17 Meters is 18 MHz 15 Meters is 21 MHz 12 Meters is 24 MHz 10 Meters is 28 MHz or right above CB 6 Meters is 50 MHz 2 Meters is 144 MHz 1.25 Meters is 222 MHz 70 Centimeters is 420 MHz 33 Centimeter is 902 MHz 23 Centimeter is 1240 MHz This one might surprise you. Amateur radio operators are primary licensees at 2.3 GHz - 2.31 GHz, and 2.39 GHz - 2.45 GHz all mode, 1000 watts! 802.11b ch 1 is 2.401 GHz - 2.423 GHz or right in an amateur band. Part 15 rules state you can not cause interference to a licensed user, and MUST accept interference from a licensed user. I know of only a handful of disputes in this band historically.
The rest of the ham bands go way on up from there, including 5650 - 5925, and can use ANY frequency above 275 GHz. Mike At 01:05 PM 10/27/2009, you wrote: >Operates from 144 to 148 MHz.
