Hi,
yes, but that wasn't so immediate conclusion... me and Qiaozhi probably searched for 2-3 days before we found that....I think Esteban will not be happy of your post, anyway.
My intention was leaving out that "details" cause Esteban and other people were worried about implications of making public domain that inside the PD was actually an Heathkit GD-348 MD...
There was a general agreement of keeping out of public domain any reference to that topic of the Heathkit stuff...also with the explicit intention of avoiding mass production of cloned PDs in Asia and other parts of the world. Or also... cloned GD-348 MDs!
Not that I belived really could happen... but you know... today you make an unuseful 10$ bottlecap-remover in western world... then after a couple of weeks you see tons of them in your local store... at 0.99$ each , ALL from a country that we know... where producing stuff is really cheap cause of low salaries...and no good environment policy at now!
Indeed I agree with Esteban when he said that, cause PD was never a commercial unit, there's nothing more than copying old schematics of other brands for personal use only...research and the like, we made here.
Also, like with other schematics here at Geotech most are obsolete stuff... not anymore in production (like the GD-348 ), so the issues about e.g. patents infringements are about academic (unless really Heathkit -or what remains of it- will jump in, really few probable I think).
That sure took another important fact, means also that many people beliving in an original Alonso's design masterpiece will be now about disappointed.
So Esteban will be even less happy about that post!
On the other hand the logic of PD is reusing existing technology to make something different, and that "idea" could stay in a patent... if it's an innovation on existing detection methods (at least this is the belief of who trust Alonso)...but no patent exist as far as we know.
But the most important issue is still that device , after all tests and cloning, failed in reproducing any LRL behaviour.
Kind regards,
Max
