Nice and easy-to-build project! Could it be possible to receive short waves (SW) with this circuit? (of course, adapting the coil turns for the SW band). Greetings from Argentina!😄

Hi Don. Can you receive AM 740 out of Toronto Canada?

[@RestoreOldRadios]

Rom - never have, but I’ll give it a try when the conditions are favorable one night and reply back. Nulling out Nashville, TN will be key. Best, Don
