If you program a Baofeng UV-5R to GMRS you need a GMRS licence. I see you understand that the radio is indeed a HAM radio and by the part 95 rules that your GMRS licence is authorized forbids the use of such equipment on GMRS. I won't get into all the details but here is the simple and best way I know how to explain this. Since no test or radio knowledge is required to get a GMRS licence its operating rules require certified transmitters to maintain the integrity of the service. GMRS is located within a tiny sliver of the part 90 commercial radio service used by business, ambulance services, fire depts, and well you get the picture. By using non certified low quality transmitters you risk causing harmful interference to other licensed services, if caught you will be held accountable. I am not here to tell you what you can and can't do but I hope you take something away from my ramblings because in the end the choice is yours.
