I have always found the "x" to be a 0.  Why do they use the "x" instead of 0?  I always
wondered that myself??  If anybody has an explaination, please post it to list.
Thanks

 I have seen a CL/D freq. be an approach freq. as well.  It is also used a lot of times
as a discrete freq. for air show control.

I think you will see this a lot.  There has not been a complete migration from the
380.00's.  Witness KNXX ground freq. is still 380.80.
