I'm also very intersted in this possibility. I just got my ticket and just finished installing a Yaesu 7800R in the FJ which is working great. Getting the license is not very difficult. Next radio mod is APRS tracking. It be great to operate the CB and GMRS frequencies with a single radio.OK, so being technically illegal but not enforced unless one is a d!ckhead, is the "hack" something that must be done by the owner (with technical prowess I'm sure I don't have at this time) or would a shop/technician be able to perform the hack? I would imagine that a business doing such may be also breaking the letter of the law and not perform said modifications.
I guess what I'm asking is if a HAM radio can be the end all for those of who don't want to have 2-3 different radios in their FJ. I do have the GMRS license for our family handhelds and what a great thing it would be to be able to do the CB thing with the off-roaders, talk to the wife and kids on the GMRS band then play with the HAMs, all on the same setup.
This is a very interesting thread, thanks!
