My guess is that the original post was simply to "stir the pot", which it succeeded in doing, but in case it's a serious post, the general public has at its disposal, with some subject to licensing, the following:
40 channels of CB radio frequencies, including AM, FM, USB and LSB.
5 channels of MURS frequencies.
22 channels of FRS / GMRS frequencies.
An additional 8 GMRS channels, which also allow for repeater use.
A wide spectrum of UHF, VHF, and HF frequencies allotted to amateur radio.
With that much of the RF spectrum, and that many options, Is there any reason to "violate Rules & Regulations" by transmitting where you ought not to, other than the notion of getting away with something?
