[Elecraft] KRX3 Issue - Jumper W4.... rtfm

[Bill NY9H]

nope,,,,,  the jumper      it is NOT between , as described in the manual ....

I sent this note to support :on July 16th,,,

the w4 jumper  is NOT between the w4 jumper block and the Kio boards,,,,,
  I kept looking to make certain i was looking at the w4 
jumper....(which I was)

and you do need to take out the general coverage board to get access 
to clip it ( w4)  cleanly...  it went right into   # 44

--------
And since it was contradictory to the instructions in the manual
i rechecked it a zillion times ... checked the schemo... then cut w4

For  Ron I have attached a pix, which will get stripped by the 
reflector for the crowd.
While there is a jumper located as described , W4 is just in front of 
the connector.
