thx for your reply nic ...
what i´m thinking about is, how can i manage this if let´s say, i like to make an overland flight with some friend and we make some stops at some little airport ... so that we can talk to each other and i can reach the info frequency from the airport ...
I have read that it is common in ul flights to commuicate to each other over some special blabla frequencys in the airband ....
