Currently setting frequencies or codes into the Com, Nav , ADF, and Transponder is cumbersome at best using the keyboard or mouse. The mouse radio hot spots are often difficult to use when flying (at least for me), and the keyboard tuning method ( using the + and - keys) is not particularly convenient either. What would be convenient, I think, is to key in the radio you want to tune ( e.g., C1, N2, T, etc) and then be able to enter the frequency (or code) numbers directly as a 4 or 5 number sequence (depending on the radio) using the keyboard number keys. And so my question to those who have the experience to know is, does this sound like a difficult programing task? Could the macro capability of FSUIPC4 be used to do this somewhat conveniently, at least for an a/c with a basic radio stack like in the C172? Thanks, Al
