4.2 circuit:91 ohms in parallel with 51+11+51 take 1/91 + 1/113 = 1/x and that comes to 50.4068 ohms... When I do that to circuit 4.2.1 I come up with 50.64 ohms... 73 Dallas, KD4HNX Whatever you do, don¡¯t fall victim to?¡°paralysis by analysis.¡± Go ahead and buy/build one and start? tinkering with it. This is a learn by doing hobby. No politician or scholar assured your freedoms. A Soldier, Sailor, Marine, or Airman did! On Wednesday, March 25, 2020, 11:30:27 PM EDT, RFy <gpdxdveil@...> wrote:
