Parachuting and radios
I hope this is the right section for my question. Do parachutists, skydivers etc. use any kind of radio during their descent? I'm sure I read somewhere years ago that the Signal R537S was a popular choice, albeit only good for receiving on the airband. I know paraglider and hang glider pilots are known to use inexpensive Chinese handheld radios around 143 mhz. Is this something parachutists also make use of, legality notwithstanding!
Thankyou.
