[Elecraft] KX1 drawing 5 ma turned off!

[John [K7SVV]]

I lost a set of lithium batteries too.  Go to N0SS's web site,
http://www.n0ss.net/k6xx_cw_tun_ind_smd_v2_assy-align_kx1_ver.pdf  and read
the documentation for the KX1 version.  Down near the end, there is a note
on the page that shows a pictures of the wires and where they connect on the
KX1's board.  It mentions that the earlier version of the documentation had
you connect the Tuning Indicator's power lead to the wrong side of the
KX-1's on/off switch.
