5 vs six:
The RX is virtually identical.
Better switching diode decoupling in the front end, Band xtal
oscillators now locked to main std, RIT added.
The Tx is the same.
The control interface works and is RS-232 compatible without purchase
of a slimy "interface box".
Bottom line: Omni-5s are showing up used for cheap. If you don't need
computer control or RIT they are a steal.
I just bought an old Omni-C for $70 (not working) which was loaded
with filters. They all (6.3 and 9 MHz) work in the new Omni series....
