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 586 AM transmit signal is carrier plus single side band (selectable), it does NOT transmit carrier plus double side band.
  • 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.

Difference Between the Paragon II Model 586 and Omni VI Model 563

From the Ten Tec Reflector December 11, 1996

The main difference between the (now discontinued) Paragon II and the Omni-VI is the way the receiver is set up. The Paragon II, like all Japanese rigs, uses a microprocessor synthesizer for frequency generation. The Omni-VI (and Omni-V) use a short range PLL (500 kHz) mixed with crystal local oscillators for each ham band. While the sensitivity and selectivity specs are similar between the two, the Omni-VI has better overall rx performance than the Paragon II. The phase noise performance of the Omni-VI vs. Paragon II is -20db better as well. (Might as well add here that the phase noise performance is significantly better than the Japanese rigs, and our specs for rx sensitivity have yet to be matched, even by the IF-DSP transceivers). The Omni-VI also has the option for crystal filtering in both the 1st and 2nd IF, while the Paragon series is 2nd IF only.

Trade off: No general coverage receiver in the Omni-VI.

The predecessor to the Omni-V and Omni-VI were the Corsair and Corsair II, which used a similar rx scheme, utilizing a PTO rather than the PLL.
