Oh boy! In the olden days I have seen mixer products charts. I think the
idea was to plot the places where all the harmonics of the two inputs
produced products so you could pick an L.O. and IF which didn't have
problems. However, I'm at a loss to point to anything. I probably have one
buried in the reams of stuff I saved to use in the future...argggg
I'm sure Excel can do this if you want to put in all the formulas (and know
what to calculate)

Perhaps a search on mixing charts or similar terms...

Hmmmm Googling this got nil:
Receiver mixer "mixing charts" -"23-channel"

I have a receiver I am considering modifying for other bands outside of
what
it covers. It is a dual conversion superhet design. Before I modify it,
I'd like to see how the new frequencies would affect the mixer output. Is
there any decent freeware available that would allow me to see all mixer
outputs and to determine if any outputs might be a problem?

Thanks,
Mike
