I have found it very interesting, informative and a real pleasure to read. In me it triggered a desire to start collection the parts for another regen, possibly built around a 6SN7 dual triode as described in the article.

I made that, adding a grounded-grid stage to the antenna: very beneficial, by the way, to preserve the regeneration control smoothness, and to avoid freq. drifts when the wind swings the antenna...
RispondiEliminaBy that circuit you can listen almost everything you get through some modern radios.
I've paired it to a Hartley (1 triode, srlf excited power oscillator) tx, and I made a few qso too, the old way (i.e. like one century ago).
They have been the most fascinating QSOs I ever made since the times I got the ham licence.
The modern stuff is amateur radio-killing poison ...

Yes, I agree with your final consideration, though I used several SDR receivers in the past and they are almost unbeatable in degraded S/N conditions.
