Hi John.....It's a home brew unit. The idea just kind off popped into my head. I have quite a good collection of roller inductors and varicaps in my junique box, plus I had already built an L-Network tuner that was easily modified to try out the Differential-L circuit. I'm going to test it out with my NanoVNA using a variety of resistor values only, then with some caps and inductors in parallel and series with the resistors to throw some reactance into the mix. With it connected to the random wire antenna I use with my regen and crystal sets, it covers the lower HF bands. 73, J.B., VE3EAR
