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

[Patrick Cambre]

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

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
