[TenTec] Orion 2 tuning noise

[Bob McGraw - K4TAX]

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.
