If you have been playing with crystal radios, then you will already know that the most critical component for radio reception is the tuned LCR assembly consisting of a ferrite antenna coil and variable ...
Crystal radio - Wikipedia
WebbThe slug is held inside the tube by wax and if you are careful and apply slow, even pressure, the slug will move to where you want it. I now had a crystal radio put together as it should be and it worked -- sort of. Below is the schematic diagram I developed for the little radio. I'm kind of big on schematic diagrams, but I wasn't always so.

Multiband Crystal Radio Set Pulls Out All The Stops Hackaday
WebbSo, what makes a crystal radio a "DX" set? Well, this one is double-tuned (L1-C1 and L2-C2) for selectivity to tune weak DX stations in the RF jungle we now live in. Some DX sets resort to triple tuning for even more selectivity -- depends on how many hands you have to do the tuning. The wavetraps (L3-C3 and L4-C4) can be tuned to reject strong WebbSlug tuned oscillator 450-470 KHZ (BFO) part 2 : how it was made in real (demo & schematic) radiofun232 14.4K subscribers Subscribe 41 Share 819 views 3 years ago PART 2 of the slug tuned...
