Hi Steve, As long as you are using a FRS radio, including the GMRS / FRS combination radios that were re classified last year to FRS, you do not need a license and you can use them. If you take your own GMRS radio (not a bubble pack )to work, you would legally have to use your call sign. At that point, everyone with a beef about your company's use of this channel would be looking for you. Not worth it. Oh, Welcome to GMRS. Keith T.
