So, does that mean the single conversion SX-42 is not as good as the
double conversion SX-43 ?

The SX-42 has a two-ganged RF section (two tubes) plus another capacitor gang
on the mixer. This cuts down on images, if properly aligned.

The '43 has only one RF stage, so the 42 might be better overall.

It has always bugged me, though, that Halli didn't use their first 10.7 MC IF
as a first IF for the higher SW bands on the 42. --Mike K.
