[Elecraft] KRX3 Install Problem: Extra Standoff, Front Panel Board

[Jeff Maass]

G'day Ron:

My profound apologies for doubting you!

I had, indeed, put the new nylon spacer in
the *wrong* hole on the Main DSP board! I
went back to give it a close look after
replying to your email, and find that I
was wrong.

Moving it now, and proceeding with my KRX3
installtion.


Thanks again! 

73, Jeff  K8ND
