All solid state microprocessor controlled HF transceiver covering all amateur bands on transmit and general coverage receive from 100 kHz to 29.999 MHZ.
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.
