Re: New style FSL Part 2
Basically the same as the G Maynard "Spiral Loop with Q Multiplier" from the 1980's, with ferrites added. :^)toggle quoted messageShow quoted text
His design was balanced, with a centre tap half way up the windings which went to the ground of the capacitor, with two gangs of the capacitor used - one going to the top exit winding and the other to the bottom.
Q multiplier on that main balanced loop winding and then a MUCH SMALLER DIAMETER pick up turn further in towards the centre of the antenna, to reduce dampening. Made for very sharp tuning - I could peak it on one or other sideband of a station, and you could hear the peak track across the audio bandwidth of the station as you tuned the loop.
