[Elecraft] KAT100 project - removing the control board

[Francis Belliveau]

Stan,

The "Allen wrench" that was supplied in the K2 kit is an ordinary allen wrench, nothing special.  Without hunting mine up it is maybe a 1/16 or 1/8, right-angle that is a couple of inches long.  Elecraft just wants you to use this as a pry-tool.  If you do not have a standard set of allen wrenches, you could maybe borrow one or buy a cheap set somewhere.

Check the K2 build manual for wrench description in the inventory, anything close will do, and instructions on how to perform this "prying" correctly as this is necessary between a partial build test and completion of the original K2.

Basically you need to lift the control panel so you put the bend of the wrench on a mount screw head and use the short ned of the wrench to push the board up at a location that does not have any nearby traces to be damaged.

I know that you are working with a K2 that you did not originally build and the step you are describing may not be necessary, but you should probably become familiar with this process any way.  You will not break anything looking at the documents so at least do that and see how "not to scary" the process is.

good luck & 73,
Fran
