Thank you. All the best. Don

Excellent circuit. I have most if not all parts on hand to build one.

[@RestoreOldRadios]

I'm glad you have the necessary parts on hand. Please let me know how it works for you. Best, Don

Surprising results! Would it be possible making a shortwave loop antenna with this same principle? Greetings.

[@RestoreOldRadios]

I would think so; it would be fun giving it a try. A short video below that shows a loop with the coupling coil in the center. This design was for the MW (AM) band. Another Q-multiplier circuit that ties back to the I.F. Hope this is helpful. Best, Don kzbin.info/www/bejne/e5KlaqeabZ5qnKssi=BQ9tvdNvIgca7f5W

@@RestoreOldRadios Thanks! I think that is basically the same principle of a regenerative receiver. I hope you decide to make a video about something similar for SW bands someday. Greetings.
