-I had the Ten-Tec "step 3" repair above performed on my Orion but it failed again after several months.  I decided to try K4ZNO's above fix.  I applied the silver conductive grease to the encoder stake pin connector as well as the two vfo encoder connector pairs.  You need to remove the front panel and the logic board per the V2 mod instructions.  Remove the knobs on the 6 small encoders (see separate knob removal instructions).  Remove the screws securing the grounding wire/lugs to the vfo encoders and remove the cables/connectors from the vfo encoders.  You then need to remove the 36 screws securing the front panel pcb in order to lift it up to gain access to remove the threaded nylon bushings securing the 6 encoders to the front panel pcb - use 1/2 in nut driver.  You can then lift up the encoder board.  I applied the grease with a tooth pick, carefully dabbing each pin.  Be very stingy with the grease because it will really spread and ooze out after you remake the connections and WILL cause short circuits in the future.  In fact, you should make/break the connection several times and then carefully clean off the oozed out grease.  When you reassemble everything, be very careful to not over-tighten the threaded nylon bushings on the 6 encoders or the push switch action will be impaired and control rotation will not be smooth.  I would say the job start to finish can be performed in about an hour and there's nothing particularly difficult about it.  I will report back in several months if the fix held.
