Is it possible to build an oscillator circuit, drive it into the ground through two electrodes, and emit electromagnetic waves at desired frequencies?

What antena are you using
@chronobot2001 3 ай бұрын
Wouldn't it be easier to fill over the strip board and solder directly to the traces? Leaving the component leads long is good if you want to reuse the parts for another project but each lead acts as a small antenna. That's probably where a lot of the buzzing is coming from. It's still impresive. Good job.

Você tem um ruído de fundo que pode ser da fonte de alimentação, não notei se você falou no vídeo que está usando fonte ou bateria, mas se estiver usando fonte, adicione capacitores cerâmicos de 100nF em paralelo com os diodos retificadores, eu tive um problema como esse na montagem de um regen. Você deixou os terminais muito compridos, isso para RF é indutância a mais, evite. É bom também evitar de usar capacitores de poliéster em RF, capacitores de poliéster são para áudio, capacitores cerâmicos são para RF. Eu monto meus circuitos usando somente componentes retirados de sucata, o custo é menor e você só tem que pagar pela placa e estanho. 73

Nostalgic memories of old 6 transistor radio which I assembled on an L-Board 5 decades back. Glad to see that it is still there! But I never etched PCBs on my own. They were easily available in local electronics shops then. I have not seen this tiny drill which you are using. 73 de Jon, VU2JO

Hi! I have two CA3028 ICs and want to try building your receiver. How should I adjust the 20k variable resistor on the transistor collector?
@amateurradiouniverse 7 ай бұрын
I adjust it to a position where I get a maximum gain in audio. Alternatively you can adjust using a DSO too, with the signal at maximum amplitude.

Went through nostalgic memories of my long lost homebrewing skills! But the maximum I have homebrewed on RX side is the old L-Board six transistor superhet radio. On TX side I had gone a little more as I could not afford commercial TX then. Started with VU2VWN QRP and upgraded to 3 x 807 vacuum tube QRO with 120 W DC input, for CW/AM in those days. 73 de Jon, VU2JO

Sir please share a schematic diagram of the voltage regulator ic and how did you connect the metal flim capacitor for reducing hf and lf switching noise from the regulator ic
@amateurradiouniverse 7 ай бұрын
You can put a 0.1 uF capacitor at the input and output of the voltage regulator IC. Additionally, you can use bypass toroid cores or inductors for filtering any remaining EMI.
