Hi all,

I have to say that I am very satisfied with my Nescaf filter. For its simplicity
the performance is great and it comes to be my favourable toy.
After bad experiences with esd sensitive parts soldering I decided to solve my ESD protection in the kitchen "lab" a bit better...

Hi folks,

as the preview MF100 chip used in the nice NESCAF filter kit is discontinued already (DIP package) the new chip has been found for this concept as the replacement.

Did You compare the results of the NESCAF filter using the old MF100 and new LTC1060 replacement please? I am interesting the differences and results... do not hesitate to share Your opinion and experiences over there.

Thank You for Your time,

Dear folks,

Did somebody tried to improve the noise floor of the LM386 by adding the 10k resistor and 10n capacitor in series between pin 8 and the output pin as it was published in the Oklahoma QRP News Letter and then after by KA4UOS in Sprat nr.79 please?

I am interested in the results...

Thank You for responses in advance.
