I purchased this transceiver in February 2018, to use solely as a Digimodes transceiver, to use in conjunction with my G3ZLP Interface, This is a DATA, CAT, and basic CW Interface. FSK/AFSK, and simple CW keyer. You can also use the interface remotely over the Internet to allow remote control of the radio and allow remote users acess to DATA modes and voice operation via the interface.
The main station transceiver - an Icom 756 Pro III, was then permanently wired through the Hunter 1000 Amplifier for just HF SSB communication.. The 850 has proved to be an excellent radio for any modes, and on A/B testing compares very favourably with the Pro III, in spite of the fact it was first sold new for over £2,000 (Inc internal ATU) in 1991, 22 years before the Pro III was sold. Accounting for inflation from 1991 to 2018 (27 years), in real terms it was over £3,500 in todays monetary value.
This particular model was a much later serial number than the earlier ones, and did not have the fault with most of these transceivers, in that capacitors went down, and one IC was prone to deterioration.
Below is the ARRL review of the transceiver from July 1991.
