About Posting a Comment

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!

Greetings Branko,

Yes the dip-meter is a very useful instrument to have.

The tone-dipper is pretty good, but my super-regenerative version is *far* more sensitive which can be handy. The tone shift of Burkhard's original circuit is a bit limited, the super-regen circuit has a much more obvious tone shift approaching resonance which makes it easier to use.

Unfortunately it is a bit harder to make the super-regenerative circuit oscillate well across broad ranges of frequency, and below about 3 MHz operation becomes difficult. Burkhard's circuit does not have that particular limitation.

Nice website by the way.

Nice to see that someone else built and is aware of the importance of this instrument! In my amateur work has for decades been a great benefit, so I recommend the construction of this instrument. All descriptions are beautiful.

Greetings from Slovenia!
