Tasa also has some SM designs that use a 74LVC components and designs with AD797 opamps .... I believe the lack of SMT parts was intentional, the target audience is different than the Softrocks and they aren't trying to compete, just expand the involvement in SDR to people who have been left out due to lack of experience in building or poor eyesight

Tasa takes nothing for granted, he doesn't just hypothesize that his design is going to perform better because he used 'X' component, they are built, documented, and measured ... If you read everything on his website I guarantee you will learn something you didn't know .... Anyone who has been working with QSD's the last 7-8 years has been influenced by Tasa's work whether they realize it or not
And don't forget to thank K5NWA next time you see him for hosting this site ... Come to think of it didn't he host some stuff for the Softrocks too a few years back?
