There are several methods which can be used. The most secure is encrypted
digital.  Spread spectrum would probably be next followed by "straight"
digital.  All three would be far beyond the capability of the average
scannist to listen to.
 
On the low end of the scale would be the inversion scramblers.  Anyone
who knows much about electronics can build an inversion scrambler/
descrambler, probably for under $20.  (This can also be used as a voice
shifter, like those used in radio/TV interviews where the interviewe
wishes anomonity and the ones used in some expen$ive phones to change the
voice!)
 
Catch you later... Good luck.
