[Elecraft] KX1 40 meter Peak

[Don Wilhelm]

Steve,

Check *ALL* the soldering with particular attention to those components 
added or changed with the KXB3080 installation.
Check all the toroids for well tinned leads - particularly T2 and be 
certain there is no short from solder buildup at the 'A' solder pad on 
the KX1 board.

If there is a lot of solder on the solder pads, remove it.  Many KX1s 
that I repair suffer from 'solder overload' due to the use of a large 
diameter solder (I use .015 inch diameter myself to allow good control 
of the application amount).

73,
Don W3FPR

I am unable to detect any peak on 40 meters during alignment, similar to what I heard during the basic KX1 receiver alignment, prior to installing the 3080 module.  Does this indicate a problem with the 3080 module construction or installation?
