Some Basic Differences Between Paragon Model 585 and Paragon II Model 586

Paragon II 586 includes both AM and FM transmit and receive, the Paragon 585 needs an additional FM board to run FM transmit.
The Paragon 585 will receive AM but not transmit AM. The Paragon II 586 will both transmit and receive on AM.
The Paragon II has a Omni VI style front button set with a more advanced logic design circuitry to allow for band stacking registers like the Omni VI.
The Paragon II has more advanced RS-232 interface/logic design to allow for the Icom style logging programs to be run. The Paragon 585 requires an optional RS232 Interface Model 258 and runs a different command set.
