Anyone out there familiar with regenerative receivers? If so...

    If you go to my website, which is http://www.the-radio-shack-special-project.com you will see my schematic of an FM super-regenerative receiver, which I made some years back and posted it around the internet.

    I am now interested, if possible, to have the unit function as an AM receiver. Would anyone out there give me some sort of component added/changing/omitting....to catch the AM band?

    I would still like to use my J-FET transistor.

    Hi
    welcome :)

    don't bother trying to convert that one, far too many changes need to be made

    there's a zillion links on google, many with circuits
    http://www.bing.com/search?q=regene...earchBox&FORM=IENTTR&conversationid=&pc=EUPP_

    go do some research and have a play

    Hello Dave,

    If you are knowledgeable with 'those many changes' that need to be made, would you kindly let me know all of them...as I would like to continue experimenting with the unit. I had gotten the unit to go as low as 50MHz, but then the regen had stopped. Could it be the choke.

    Hello again Dave,

    I just completed a regen am receiver that you suggested I do... from this utube videohttps://www.youtube.com/watch?v=4sySm9WTaZU . I tried to get it to oscillate, to no avail. Is there anything you see wrong with the schematic?

    Once more Dave,

    When you look at the video...there are 3 links below...click on the 1st link...it will show you the schematic I used to make the unit.

    again, thank you for replying to my concern.

    a friend, Patrick
