Not to hijack the thread, but I was seriously disappointed in the quality of radio communication when I left hang gliders for sailplanes. With 2M amateur band radios and the repeater system in use worldwide, like MANY savvy and dedicated hang glider pilots, I enjoyed crystal clear comms with fellow pilots and hundreds of discrete simplex and duplex frequencies. I often "dialed up" the freqs used in Telluride while flying in New Mexico just to talk to my buddies who were in the air in Colorado.

Once I got into sailplanes, I was forced to accept the low quality RX/TX, minimal frequency choices and lack of a repeater network. I almost felt like smoke signals would be about as good.

So I carry a tiny 2M radio just in case. (Along with cell phone, InReach, spare battery, etc.)
