Long time ago I was told I can replace a crystal in a CW transmitter with a VFO to adjust the frequency. I never tested that and I never built a VFO. Here is my first 7 MHz variable frequency oscillator build ( almost a fail and now I also know why ).
Special thanks to @MIKROWAVE1 for the great videos on VFO's. I am learning a lot from those and the lessons are also great for improving the stability on regen receivers too.

DX Explorer is a channel with amateur radio related videos on: schematics, reviews, homebrewing and much more.
I am passionate about amateur radio since childhood. I got back into the hobby in 2016, while living aboard my sailboat. I received my license in 2022. I like QRP mostly, experimenting with all modes. But I am old school, so I prefer SSB or CW.
If you enjoy the videos be sure to subscribe !
