[MilCom] Questions from Pt. Mugu Programming / Airnav...

[Michael Comer]

>From the IFR Supplement:

"Frequencies published are transmitted and received and are monitored unless 
otherwise indicated
by the letter "x" following the applicable frequency. This means that 
frequency with an "x" can be
requested through the control agency under which it is listed."

Basically a discrete freq.
