Gone are the days when 123.3 was used pretty much by gliders alone. A couple of years ago, the frequency was also allocated here in Arizona to a local commercial operator for ground to air operations. When they first came on the air, they started yelling at gliders to "get off their frequency". Even now, when they are not overpowering us with their high-power transmitters, we get users from nearby Mexico stepping all over us. Now, many of us don't use 123.3 - sticking with either our airport frequency (122.9) or 123.5.

Finding frequencies for glider/glider communications in the aircraft band is going to be a challenge.
