Re: [TenTec] Orion Filter Controls

Grant, I don't know why mine behaves differently to yours but I 
understand from Lee, KC9CDT that his also behaves the way mine does.

I have just looked closely at mine again and can confirm the following:

When on USB, Hi Cut is depicted correctly on the graphic but Lo Cut is 
not.  When Lo Cut is adjusted the graphic shows the whole passband shifting.
The opposite is true on LSB, Lo Cut is depicted correctly but Hi-Cut 
causes a complete passband shift as depicted by the graphic.

The issue is therefore sideband dependent but in any event it is only 
the depiction that is incorrect.  What actually happens to the passband 
when the cut controls are adjusted appears to be correct.

All very interesting but only a niggle.

_The synthesiser control issue is by far the hot potato here_.
