The 2T H-Mode Mixer with FST3125 has been already applied as a mod to replace the TUF1 mixer giving a very high IP3 improvement. Having a strong front end conversion followed by the classic QSD with FST3125 will certainly be appreciated by HF people and give a distance to many commercial receivers.<BR/>Although the TUF replacement with the H-Mode Mixer is a 1 to 1 job, I can deliver all info on this mode.<BR/><BR/>73<BR/><BR/>Gian<BR/>I7SWX<BR/>I can delGian I7SWXhttps://www.blogger.com/profile/09052848611660319276noreply@blogger.comtag:blogger.com,1999:blog-13992472.post-44007268512575879772006-11-05T03:48:00.000-05:002006-11-05T03:48:00.000-05:00The K2 is a good choice for experimenting.

See: http://www.pa0sim.nl/Hardware.htm<br />All the processing is done in the software.<br /><br />73 Jan PA0SIMAnonymousnoreply@blogger.com
