- You can build this 40 Meter LPF kit from QRP Labs and upgrade it from 10 to 40 watts! How does $5 US sound?
For 40 watts be sure to change capacitor voltage ratings to 200 V

Great informative video! The output of the NanoVNA is square wave so cleaning up that signal is even more difficult. Very impressive.
Thank you RMD for your interesting comment!
