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.

Yep. The soldered jumper on the older boards is between the connector and
the KIO3 board. There's an arrow and callout in Figure 39 in the KRX3 manual
showing where it is.
Early on Wayne moved it to a plug-in jumper in the connector because it was
hard to get to the soldered jumper on the RF board. Besides, if one wanted
to use the K3 with the KRX3 removed it's necessary to replace that jumper as
described in the manual.

It IS in the instructions that our older boards had a wire which
needed to be cut....
and that jumper is indeed partially hidden by the bandpass board,
That jumper's location could be better identified in the instructions, as I
recall it is to the rear of that jumper block, not in front of it .
It went in fine and does work great.... still calmly awaiting the
firmware to allow being able to split it off to another band.
