AW: AW: [sdiy] Re: OTA nonlinearities

[Czech Martin]

Yes, I thought about that, too. It was just an exercise but worked well.
I even thought that one could use two 1496 for that purpose, but no way.
Ok, the loger can be done with (japanese) duals.

btw.: somebody posted that some of these duals are out of production.
I lost that mail, and http://www.buchi.de/sdiy/ has a black hole there, too.
Do you still have this mail?

m.c.
