Re: K2 Optical Encoder Test Problem

John Graf
My K2 just started doing the same thing.  I redid all the solder  
joints between the board and the encoder, then checked the list  
archives to see if anyone else had that problem.

I am going to order and install a new encoder.  The reason I think  
that it is the encoder itself is that with the knob off and the nut  
on the encoder loose, I can wiggle it around to get it to work.  You  
would think that would be a bad solder joint, but as I said, I redid  
all four wires and checked them with an ohmmeter.  I think it's  
something internal to the encoder.

It's not a hard part to replace.  I will let you know how it goes.  
In the meantime, I am using rig control to adjust frequency. :-(

73,

John, WA6L
