content: There are many good groups on Yahoo. I was already a member of Yahoo Groups so joining the VNA group was simple. Yahoo Groups has been around an awful long time and it is wise to not discount its content 😉Groups, like the one I own, are restricted (membership requests needed) for a very good reason...... it virtually kills spam on the Group making it far more enjoyable for members. In restricted groups just get spammed to death by sex related stuff 😆

content: Hello Tom,I am very much interested in that project.A test setup is already finished.Do you have maybe also an operating instruction manual?To read the way of operation out of the source code is not so easy.73 de Rudi DL5FA

content: The basic AD9851 + AD8307 + ATmega328P architecture is nice. Might be nice to spin it into a single real PCB for manufacturability benefits.
