    Very good video Jomon ❤ Next time please make a Arduino based morse code translator with keypad input, that make automatic translation when a key is pressed

      Thank you. I will make the Morse code translator.

    VWN QRP transmitter made a revolution in HAM radio operation on Amplitude Modulation . Thanks Jomon for reproducing the circuit.🎉

      Yes. I think we need to bring back the AM. Because it is very easy to generate compared to SSB

    VU2VWN xmtrs were heard a lot in Kerala even till mid 90s. Great video! I prefer your original voice & presentation. But if this new narration will give you more reach, all the best!
    Hope to hear at least some videos in original voice & language.
    Good luck!

    Thank you Jomon, I will play with this transmitter using a cristal oscilator even I own a micro Bitx from Ashhar Farhan VU2ESE. Please share more videos of your homebrew projects. Kind regards CE3-THK

      This is a very interesting project. don't turn on this TX without connecting the proper load. This Tx not only CW. We can make AM with modulation transformer

    I think there is an error in the schematic. If the zener diode D2 is installed like it is shown in the schematic, the collector of the output stage transistor bd139 will be permanently shorted to ground. Thus, no rf-energy can be coupled into the tank circuit. D2 should be pointing in the opposite direction, so it can clamp the collector voltage to a value agreeable to the bd139.

    Sir, could you make home made circuit of signal generator and F.M transmitter up to 30 k.m range...☺️ If it's an illegal then F.m radio receiver with one transistors using Bf 199 design something quite better stability and cleaned Sound.

      Making FM transmitter for long range without license is illegal in india. I already uploaded making video of one transistor fm receiver ua-cam.com/video/L2vJWp6Amc4/v-deo.htmlsi=GaZIuZ4MNOAX7_8S

      @@MrtechElectronics Yes I'm working on It, but I made in unprinted circuit board as I don't have circuit printer machine here in Assam,some components are also not so available here,The radio I made from your design picked up a channels but due to not having proper antenna it's getting worse So,I'm trying to figure out the problem of Antenna simultaneously,Actually I would like to request you to make another design of one transistors f.m Receiver which works by transistors B.F 199 which is also far more better than bf 494 or bf 495 medium wave transistor if I'm not wrong..
