Re: [TenTec] Orion 565 tuning encoder

["Bob McGraw - K4TAX" <RMcGraw@Blomand.net>]

Shouldn't the two outputs be 90 degrees quadrature?  "A" leads "B" in one 
direction and "B leads "A" in the opposite?  I seem to think so.  I had to 
replace the MULTI encoder in my Eagle and I seem to recall it worked this 
way.
I actually opened the original one, cleaned it, put it back together and it 
works. I don't advise this however, unless you have a lot of spare time with 
nothing to do, good illumination and steady hands under good magnification.
