Ok, GMRS newb here. I had FRS/GMRS handhelds from Midland recently and just payed for my license and bought a mobile radio that I plan to use for Jeeping and in my daily driver pick up. I have read all the regulations that I could find over GMRS so I understand to use your call sign when entering, every 15 minutes and when leaving the net. Questions that I have relating to actual use of the call-sign is this: Do you use the NATO alpha numeric alphabet when stating your call sign (alpha, bravo, charlie, etc) or normal alphabet (A, B, C, etc)? Context, I used CB a decent amount when I was a kid back in the late 80's and recently with my Jeep. Most of my other radio training comes from my time in the military using the vehicle radios and limited use of HF man packs. Thanks!
