Is that what you would call a device that takes the signal directly from the antenna before passing it on the the rest of the circuit?
My little one (11 years old) recently built a crystal radio but even with my long wire antenna from my shortwave radio the signal is weak.
Also the kit does not have any ground and from what I remember from years ago that these types of radios have to be grounded? No reference to grounding it at all with the instructions?
The kit consists of a variable capacitor, diode and a couple of coupling capacitors. It has a pre-wound "AM Inductor", everything is correctly installed and there was no poor soldering?
Can anyone point me to a amplifier that I could put before everything in the circuit?
Thanks
