OOOPS, I got it backwards - a new encoder shaft measures 0.251 with my
calipers (close enough to 1/4 inch) while an old encoder measured 0.235
inches - close enough to a nominal 6mm.

Don,
If you have the new encoder (with the encoder board), you have the 6mm
shaft. The old encoders have a 1/4 inch shaft.
You can tell which encoder you have by removing the VFO knob. Look to
the right of the encoder shaft and you will find a small hole in the
front panel metalwork. If that hole is empty, you have the new
encoder. If instead you see a green pin in that hole, you have the
old encoder.

I am going to order a VFO knob from the 73cnc site, I need to
determine if I
have a 6mm or 1/4 inch dia encoder.
I tried to measure with my cheap plastic ruler. 6mm is too close to
1/4 for
me to be sure.
I have #7621 purchased 12/16/11.
