Q-Multiplier Circuit - A Simple Circuit to Improve AM Radio Reception Works w/ AA5 or Transistor...

A simple Q-Multiplier Circuit designed by Raymond Haigh. The schematic and other cool projects by this author: https://www.yumpu.com/en/document/rea... The Ferrite Rod (Amidon) is a Type 61 material 0.5"D x 7.5"L. It's wound w/ Litz Wire 180/46-44 Special Blend (Inductance ~220 uH) from: https://www.mikeselectronicparts.com/... The Variable Capacitor is also from Mike's Electronic Parts at: https://www.mikeselectronicparts.com/... The two sections are tied together to get ~15 to 532pF. The LC Circuit easily covers the (BC) AM Band. I used a 100k potentiometer in lieu of a 10k and a 2N5457 JFET in my design w/ good results. The one-sided PCB is 5cm x 7cm.
