I very much enjoyed today's video. I think this is a great idea making thease shorts. As usual very well presented. Could you please at some point in the future show us how to construct that lovely MW antenna you were using. Thank you.
Very cool. It worked! I used a long wire antenna, a ground wire hooked to a water pipe, a D18 Germanium Diode and vintage headphones. I heard a powerful sports station very clearly. I live in the San Diego area. Pretty cool that you can pick out sound from radio signals with such simple components. Thank you!
Yea, really effective! :) I live in Houston TX where there are a lot of strong stations. The result of this experiment is a jumble of stations all blabbing away on top of each other!
Neat. Glad I found your channel. I may give this a go if I have a 1n34a, but even a low voltage biased silicone diode should work according to Gasslinger's experiments. I am aiming to build a direct conversion receiver, but a crystal rig might be a fun warm up.
I would love to know how to make this antenna, is it possible? At least at least have the plan with the wire length details. Thank you very much, very nice video that I share with my friends.
excellent demo & explanation, I love anything about crystal sets..but I got you beat...while experimenting with a crystal set, I connected an old CB antenna to the hot side of the mic input on a laptop-when I monitored the mic input using VLC media player, I heard my local MW station loud & clear (no diode, no ground, just a single conductor antenna). This was accidental & I'm not sure but I'm thinking the mic input has some sort of diode protection that's demodulating the signal, & if so, technically the laptop is replacing the detector, headphones, and ground.
That wouldn't surprise me. There are documented cases of people receiving stations with fillings in their teeth. The body acts as an antenna, one filling acts as a detector, and another loose filling or bridgework would vibrate allowing the person to detect and hear a radio broadcast.
Similar design antenna like that of yours, you are using both ends of the antenna, one to ground n earphone, n other ebd to gang caps. Does the ground end of the antenna needs to connect to the earphone too?
The tuning knob has a switch, which is turned off. I can get a couple of stations with it on. I only get one when it's off. It switches a 360pf variable cap in and out of circuit. I've been called out before on this, which is why I recently added labels to the switch so it can be clearly seen if it is off or on. 750AM radio has an antenna 4 miles from my house, so that's what overrides everything else. I have an in-home transmitter, so if I'm inside the house, that is the overriding station.

That was just another great video. THANKS
Imp. Question-sir, to add the metal/gang capacitor in this crystal radio, do one needs to make that loop/spiderweb antenna or a horizontal antenna?
Awesome, love the "Snippets"
What is the type n value of the capacitor 1 in your first diagram? Is it a polystyrene or ceramic one?
Inductive Amplifier that is new to me I learn something new today thanks !
Nice try but the antenna in the video has a tuning knob which is not the radio shown in the pamphlet.
The tuning knob has a switch, which is turned off. I can get a couple of stations with it on. I only get one when it's off. It switches a 360pf variable cap in and out of circuit.
