I have an older Sky Melody vario that I believe was considered a "light" version as its not in a plastic case for weight savings. It worked great for years but now doesn't appear to be "in tune" anymore. It's very fuzzy on the FRS receiver and can't even be heard outside of about 10 feet from the airplane. I'm assuming like other radio transmitters, that it's in need of being tuned up. Anyone know where to start?
