[Boatanchors] 455Khz IF upconver to 21.4Mhz?

[Eugene Hertz]

Hello all,

Along with many of my other birdbrained schemes, I now have desire to connect a panadapter (CEI) that has 21.4Mhz IF to my hammarlund SP600 at 455Khz.  Does anyone know of an existing module or tried and true circuit that can do this conversion? I know that a mixer with the right glue parts can do this, but I am only good at constructing circuits, NOT designing them!

Any insight is appreciated!
Thanks
Eugene
PS Any one have suggestions as to where the best tube/pin is to get the IF from the SP600? THANKS!
