Folks:
If you have my CW Tuning Indicator installed in your KX1, PLEASE READ THE
FOLLOWING NOTE from Bruce Beford, N1RX.
Apparently, the point at which I originally instructed builders to attach
the +DC wire
I have a corrected set of installation docs available on my web site.
PLEASE NOTE that this correction is NOT currently reflected in the
pictures which are shown in the KX1 installation docs, but it WILL be shown
as soon as I can get a good quality picture from Pete, NU6Q, who provided
the original photos. Hopefully in a few more days.
Sorry for this error. It should not have occurred.
73, Tom N0SS
