===== 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.
