Per Larrys comment, to the best of my knowledge the most current W7IUV design is captured in his Revision 5 document, and the schematic within this document that's the most current design is identified as follows: Revised 13Sep09.
Here is a link to Revision 5 document: http://www.mtmscientific.com/preamp.pdf I built my W7IUV preamps per the "Revised 13Sep09" schematic which I'm pretty sure is the most current design. 73, Don (wd8dsb) On Tue, Nov 21, 2017 at 6:38 PM, <[email protected]> wrote: > Larry, W7IUV, made some changes to the design over the years.
