KX1 40 meter Peak

Steve Watkins
All:

I am in the process of doing receiver alignment on the KX1 after installing the 3080 module.  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?

The 20 meter peaks are dicernable but not the 40 meter now?

Thanks, Steve
NE7RD

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,
