Ham Radio

[Nowhere-Man]

Tonight I was looking at the Hartley oscillator circuit. To summarise what I learned the cathode in the normal circuit is at - and tapped about the centre of the inductor (in parallel with its capacitor). Then each opposite of the inductor connect to anode and grid, through blocking capacitors. The tap is said to determine the feedback. ARRL is often a bit lacking in down-to-earth explanations. I sometimes wonder if the Radio Corps students back then genuinely followed what was taught in class. It took me a lot headaches to understand that feedback can simply detract from or add to the cathode grid signal.
My hope is at some point I may be able to build a receiver. I bet that would be quite a kick..
