Oh, it's also worth noting that, if you want to listen to hams and
expecially aeronautical communications, you'd better know where to
look. Especially when it comes to the latter, it would be hard to just
stumble across the right frequencies unless the fine tuning wheel of
the 7600GR is in *exactly* the right position. Search the web for a
list of aeronautical frequencies and a description of where the amateur
bands are. Then tune to these frequencies, tuning slowly.
