In this video, I describe with my funny cat MASHA how to make a detector receiver.
I don't have any result but its be interest. You need for it. Some things like headphones with high amont OMS are hard to buy.
You can take any simpleple head phones with transistor instead.You see, the fundament of detector receiver is oscillatory circuit.
And we need to choose right number of ring in coil, and right antenna. I can't do it because I am a beginner. Here I describe how you can make it buzz.
Transistor needed to make the circuit sound louder.
I used a TV antenna becouse they have a stronger signal.
What we need?- Ground (can take from eletcric plug)
- Varnished copper wire, need point therty-five
- Diameter (ten мeters long)</li>
- Sewer pipe forty мм diameter</li>
- Ceramic capasitor two sosund and two hundred
- Headphones with high amont OMS (I bought in local market)
- Battery compartment for two AA bateries
- Two AA bateries
- Transistor PN2222A
- TV antenna
You can make a coil, but I did it and nothing hapen.
Then cut eletcric plug,
Isolate two cables,
yellow and(yellow and green) cable (it's important to make sure it's ground)
To ground, anttena add jumper wires with breadboard
Set the components like schematic.
As a result a lisen the zzzzz.
I use material from book borisov young radio hobbyist and YouTub channel YONG RU.
