4m converter breadboard (2N3904 oscillator and NE602) |
Next stage is to breadboard the TX mixer and buffer stages.
Simple QRP projects, 10m, 8m, 6m, 4m, FT8, 160m, WSPR, LF/MF, sub-9kHz, nanowaves and other random stuff, some not related to amateur radio.

In my opinion we have just passed the solar peak. We can expect a few years of good conditions, but I expect the trajectory to be slowly dow...

Hi Roger,
I think I'm going to order a 42Mhz xtal and follow your work, hope you don't mind :)

Good start for the transverter project!
All the best

Hello Roger !
Have you worked on HF designs before ?
It's because I see you putted a resistor across the Xtal. This is done to reduce the fundamental frequency of the Xtal.
But not every body knows that ;)
