[aprssig] VHF Aircraft Channels

Ground stations still have a station license and an assigned frequency. 
DO NOT just pick one at random, you could interfere with an aircraft 200 
miles away. This sounds like it might fall in the "test flight" 
category. Actually 123.45 is part of that assignment and the rightful 
users go nuts with everyone thinking it is for air-to-air chitchat. Even 
some official publications have it put down for that. ARINC just down 
the road can help you if you need a frequency assigned to you. If you 
want to "just do it" and hope no one complains use 122.75. This is 
officially for air-to-air chitchat and carries no important ATC or FSS 
traffic. Please keep in mind with the ADIZ (security measures) around DC 
that what we do here is much more carefully monitored than elsewhere. If 
you want to get some real quick attention, use 121.5 :)
I would think about using ham radio for this if you can. You can easily 
talk all day on 2 meter simplex and never hear anyone else.
Feel free to contact me if you need any more advice. BTW, I may be 
flying a 144.99 input/144.39 output digi in the area this weekend to see 
how it works.
