You know how you can tell no one ever builds
something you write-up?
When there's an error in the diagram
and no one calls you on it!
The diagram I supplied for building a simple
converter to get those 200-400 KC "Range" receivers
off the shelf has an error.
Please delete the old file.
I've corrected it and built the circuit to confirm
the correction. I used a 4.2 MC crystal on this one
and it works fine.
Corrected diagram:

A better input tuned circuit will improve image rejection
at the price of greater complexity.
