[Elecraft] New KX1 with KXB3080

[David [M0WAM]]

Hi Jim 

I did just what you are thinking when I built mine (KX1, KX1AT and KXB3080).

First I built the KX1AT board , then made the LPF1 board from the KXB3080. I
then built the main board incorporating the input filter changes, L6 on the
underside etc.  I fitted the LPF1 board instead of L1 and L2 (leaving the
green wire free), after plugging in the KX1AT temporarily to check the
position of the LPF1 board.  A tight fit...  Having done the testing and
aligning I built and fitted the KXB3080 board, re-aligned and all was fine -
no unsoldering needed.  

I found it useful to mark the KX1 assembly instructions at each point where
a change in component value or procedure was needed, but the whole process
went smoothly thanks to the invaluably colour photos in the downloaded
manuals.

A tip which may be helpful is to solder the ground wires on the crystals
very low down to avoid fouling the battery boxes when the case goes
together.

Regards
