Rick,
Unless something changed in the rules that I don't know about, which is possible, encryption on ham radios is illegal.
As to why different schemes, it may depend on what radios are popular in a given area.
Why trunking I have no idea.

1yr 3mo new 59yr old ham seeking info on p25 vhf and uhf rigs. Cost associated with rigs and software packages. Of the Ham clubs associated near me one uses uhf encrypted one uses vhf and one uses vhf trunked. Why do they all use different rig setups? Where they can control who's in and who's out?
