[Elecraft] KX3 2m module problem: missing band map for 144

[Louis Brown]

Just sent this to tech support:

——
Just installed the KX3-2M but had a hair-pulling time getting it enabled.  Turns out the Rev A3 (8-15-2014) instructions are out of order.

On page 3, the 5th bullet has the user edit the BND MAP to enable 144.  The problem is that 144 does not show up until the transverter is enabled on bullets 8 - 13.  The 5th bullet needs to be moved after transverter settings, and after a power cycle.  Bullet 6 is a duplicate of bullet 4 and needs deleting.  Several other users had problems, reporting that it worked after several attempts, which makes sense since the transverter would have been enabled on the second attempt to edit the band map.

Thanks,
Lou
