A buddy and I are planning a dual-sport ride. I am thinking of making a DIY helmet comms set using my FRS radios, and buying a PTT button with headset and boom mic. Has anyone else pieced together their own "sena" type outfit? I don't need bluetooth because I don't listen to music when I ride and I don't answer phone calls. What experiences do you have? Motorola Talkabout T7150. Thinking about a planet headset dot com headset. An outfit called rugged radios dot com makes some neat stuff, but I don't have that in the budget. Thank you.
