Re: Balun One Nine: cutting R1
notice that the V1 has the central tap, while the V2 doesn't so with the V2 there's nothing to cut

Re: Balun One Nine: cutting R1
Thank you, Egil. I guess I should clarify my question: How do I physically cut the resistor?

If someone here likes fiddling with a soldering iron, here's the schematic for a regen https://www.aa5tb.com/regen.html https://www.aa5tb.com/regen2.gif I'm posting it just since I like how well it's designed while being simple, let me start from the input stage, the common gate JFET does multiple d...

simplest antenna
