Does anyone have any suggestions of a good communication system between a PIC and a VO in terms of radio equipment, ear-piece, etc? I don't exactly want a push to talk feature as my hands will be on the remote control. Occasionally, I would also like to use my FPV goggles and would like a VO to keep an eye on the drone while I am doing so. Also, I understand that certain types of radios requires licenses. Any advice or help would be most appreciated. Thanks so much.
