Probably you need to go through the radio, unplug each and every board and
connector, and re insert them. Just normal radio maintenance in my opinion.
Also a wee bit and I mean a wee bit of Cramolin from Radio Shack might be
advisable on each connector. Just remember, more is not better.
What you are hearing is zipper noise from the steps in the rotary encoder.
Likely a few milliohms or resistance on a cable connector is the most likely
cause.

Subject: [TenTec] Orion 2 tuning noise
Just noticed this tonight: Tuning through 20m, there's an audible "click"
with each step in frequency (each 10 Hz with 10 Hz steps, each 1 Hz when 1
Hz step is selected, etc.) It is impossible to tune through the band
listening for activity, since only the strongest signals would make it
through this noise. When I stop tuning and settle on a frequency,
everything is fine.
Any suggestions?
