Comments are moderated before they will appear on the website, this is a manual process and may take some time. Please be patient.
Author Name is a required field.
Email Address is optional, but without one I won't be able to contact you back. It is never shown or linked on the website. You can always just email me if you'd rather not post a public comment. I generally reply in-line with a comment rather than email you back, unless I want to discuss something in private or off topic. Please check back to see when I reply.
Website URL is optional, if supplied the Author Name will be hyperlinked to this URL.
You may use wikitext in the body, preview may be handy here. Don't worry if you can't figure them out, just give me a hint what you want linked to what and I'll do it during moderation. Wikitext is not BBcode!
Spammers: Please don't bother wasting your time scripting up posts to this form. Everything is moderated, your post will never be seen on the web even transiently, there is no way to even view it by its internal ID, it will never be indexed. I will simply delete your post in the moderation interface. If I'm your target audience you're really on the wrong track; I'll never click on a URL in your garbage. The post content is not emailed to me (and I don't use a Win32 mail client anyway), I view the posts in plain text in the moderation interface so no clever tricks of any kind will make anything you type be interpreted by anything other than me, a human. Just give up and go elsewhere please!

Is the diode shown the zener you refer to in your text please? And can I substitute a 2n5819 for the mpf102? Or maybe a bf245? Thanks

I have often found 4S7NR articles to have been plagiarized. He seldom gave the original author any credit even though he did in this case.

Hi there. I have this circuit built, from Kitchin's QST article "An ultra-simple receiver for 6 meters". It's oscillating but I haven't heard any signals, maybe because of a lack of 6m activity in my area or because my coil size is out of band.
Do you think this circuit could be used on 10m in regen mode for cw/ssb copy? What components would need to be tweaked?
How would you rate the performance of this set compared to your "euro set" regenerative FM receiver (http://www.vk2zay.net/article/89)?
Finally why do you say that building this circuit on an unetched piece of PC board limits its performance? What construction technique would be better?
