As discussed in a forum--thread some week ago, please have a look into the VOR distance showing in NAV-display. If I insert an specific VOR in the FMC, I get it displayed in the NAV-display, that´s good so far . But you will get VOR-informations regardless of the distance to the VOR. Normally one can safely receive VOR over a distance of 100nm, sometimes also 120-130nm, under best conditions up to 150nm. Please check this issue.
Attached an example - for me a personal Highlight: more the 7800nm miles away .
