Hello,Tasic I am interesting for your circuit design.
In fact, I am also making tiny SDR using 4066. http://sdr.sblo.jp/ Cheers, Kazunori Miura JA7TDO ----- Original Message ----- From: "Tasic Sinisa" <[EMAIL PROTECTED]> To: <[email protected]> Sent: Thursday, July 20, 2006 9:23 PM Subject: [soft_radio] 4 new HF SDR designs from YU1LM/QRP > Hello SDR OMs, > > I uploaded 4 new SDR designs.
