[TenTec] Orion 2 tuning noise

[K3GHH]

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?
