   I have also heard on many many occasions, situations where I hear music 
and other non-military communications coming over a specific UHF freq 
whenever military planes are approaching, and this sounds very similar to 
what was described by the initial post.
    What I've heard is music and other commercial radio coming over 255.4, 
which is the FSS frequency.  I've heard this on literally hundreds of 
occassions, and EVERY time it happened, shortly after hearing it, I monitored 
Otis F-15s come into the area.  This music kicks on and off, as if being 
keyed up by the plane, but the F-15s obviously transmitting the music or 
transmitting on that frequency.  My guess is that they were transmitting on 
one of their regular frequencies, while passing over a commercial antenna, 
and their signal was mixing with the commercial signal, mixing in the 
antenna, and re-transmitted on the 255.4 freq.   I guess that it could also 
be some similar kind of mixing inside my receiver too, except that the music 
is generally heard well before I am able to pick up the F-15s themselves, and 
the music dies out prior to my picking up the F-15s on their actual freq, 
which is generally in the low 300 MHz range, although it could be the 262.0 
Otis Opps freq causing the symptom.  
    I have also heard music actually coming from military planes, but only 
from planes like P3s or KC135 tankers and such, which have people besides the 
pilots on the air.
