Re: VE3EFJ third mixer mod for the R4C
¿ªÔÆÌåÓýHi Glenn, ? In 2022 there was an attempt to have Harbach Electronics offer the boards and a parts kit.? My old Gerber files were not readable by most current PCB programs.? A ham in Germany was able to get my old Gerber files converted to current formats.? By the time that problem was solved Harbach had lost interest.? I just sent an email to Dieter asking if he could locate the updated Gerber files and send them to me.? If this can be accomplished I would be happy to turn them over to anyone who was interested in running another batch of boards.? Call me if you want to chat. ? Rob, NC0B 303-995-2749 cell ? ?

You wrote, "My MIX-4 has a J309 FET properly coupled to the 5695 kHz IF tuned circuit, and separate ports on the NE602 Gilbert Cell mixer for the IF and the LO injections" ? Have you given anyone permission to reproduce the PCB's for your R-4C mods? I would love to install all of them in my 4C. The parts can be sourced but PCB's would be needed. ? Thanks ? ?
