Yup, DIP headers and 4148s are the way to go. This hack is years old. I did it in the late 80s and it had been around a while by then. :)

From poking around the band modules on the AUX-7 I acquired,
they just seem to be diodes connecting pin 1 to everything else,
right? Is there any reason I can't just roll my own with 1N4001s
or something similar?
The two modules on the board I have appear to be TI parts,
labelled BC1206. I have searched high and low but I can't
find a data sheet, or any reference at all, to a TI part
bearing that number. Anybody have an idea what those might
be?
Cheers,

P.S. I have two band modules covering 0-1MHz I would be willing
to swap for some WARC coverage :-)
