This weekend I tried the If alignment and screwed it up. The first step of tuning the coupling coil between the 1st and second IF required quite a large adjustment, it seemed, and I did get to the correct response, but then the end-to-end sweep came out far too narrow. Will have to go back to the beginning and make sure the loading circuit is correct and connected to the correct point, leads are extra short, etc. etc.
Are we having fun yet?
