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.

Regards,

Alan

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.
