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.
