[TrunkCom] while we are on the subject of encryption

[JERRY NONE]

I hope that the radio scanner makers keep up with the
technology.  Does anybody know if this would be
backwards compatible. Could a system be P-25 Mixed
Mode and P-25 TDMA or 100% P-25 and P-25 TDMA? 

What exactly are the differences between CDMA, FDMA, &
TDMA?  Which one is better for Public Safety / Public
Service? 

Would making systems go P-25 TDMA make them more like
TETRA or NOT?
