I was just following a tutorial which pointed me in the direction of the east midlands eme on a frequency of 353.5 as stated on the charts but i couldnt pick it up . I then looked at my map in fsx and it has a different frequency of 353.0 , have i missed something ? do i need to update them somehow ?  thanks for reading ...

I would try this site: http://www.aero.sors.fr/navaids3.html

 

They also have other must-have updates such as the magdec one. It's a trustworthy site (PMDG even links to it on their forum).
