Twinplex Regenerative Receiver part 4

I ran a test with the receiver with a 9 to 3 coil and picked up this beacon station WLO. I wanted to make sure everything worked before mounting the front panel for the final time. I also picked up several religious broadcasts so I figure it must have been up in the 8500 over 40 meters anyhow.


I also built a 40 meter coil 9 to 2 turns. I listened to several QSOs and what sounded like PSK so I am happy with that coil.





 I mounted the knobs, and bolted everything down good. I still had a couple of hours to kill so I decided to try to build an AM coil. I found an AM loop stick that came in one of my son's old electronics kits. After mounting it inside one of my coil forms, I added 2 loops for a tickler coil. Worked first try! I found stations from 620 up to 770 so far. but it works surprisingly well.




The AM loop stick is laying on its side in the coil form. I do not know if that causes a problem or not. I'll try centering it to see later.
