Hello all.
Recently I was flying to Innsbruck airport. I did the visual approach, which of course requires DME's.
At the departure airport, i regularly got ready for the departure and approach as well. At the approach part, I couldn't seem to enter the VOR frequencies in the VOR L, and VOR R fields, located on the NAV RAD page. It said "Invalid Entry" every time. I was able to insert frequencies manually in the PMDG 747.
I was wondering if they were any special way to enter these, or am I just not smart enough to figure that out?
I appreciate your help.
