    I have made a website about this radio.
    www.la6nca.net/homebrew/matchbox/index.htm
    Uffda, Oscillator bias resistors is missing in schematic in video.
    It is right on this page.
    R and T on xtal have also been swapped.

      @LA6NCA if you could publish the dimensions on the various coils used on your homebrew projects would be fantastic for those of us without 3D printers. I have a No.48 set I would to get up going it is only a case of getting my self organized. Always enjoy your content I am also learning CW so your sending I can copy a little bit. I like how you write down what you are going to send must help with your sending. What speed do you send at.?

    Awesome as usual. In Australia we have a person who also does homebrewing, and often with second hand parts. He is Peter Parker VK3YE and also on RUclips. Both you and Peter are very inspiring, especially in terms of showing that great communications can be done on the cheap. Thank you again for showing.

    Your English at the start of the video was good enough that I don't think you would have needed to use the voiceover.

      Thanks for the comment.
      It was easier for me to do it that way.
      It is not so easy to speak without a strong Norwegian accent.
      Many from Norway have this (Jens Stoltenberg in NATO)
      I get to practice a little.
      Some have liked it and say that they can better understand the video.

My smallest one has been on a Altoids tin Can and also on a tuna tin can. None of those my own design. Congratulations!!! The antenna is very cool and simple too.

    I love the small, compact rig. The only issue I would have is using the small key. Not having a sidetone is not a problem for such fairly basic circuits and 0.3 watts is plenty enough as I have been strictly QRP for years while using only dipoles and end fed wires. Take care and 73 de wa4jat

    All you'd need to add is a fishing pole and a small tackle box with lures, a candle and some tinned meat for lunch and this beauty would be exceptionally covert.
    I wonder just how much smaller this could be made with SMT components.
    Thank you. You gave me the first smile of the day. Be blessed.

      Thanks you for your comment.
      The mixer is the ADE-1ASK or ADE-2ASK from Mini Circuits
      Many other mixers from Mini Circuits will work.
      Just look at the data sheet that they are designed for frequencies as low as 80 meters.
      Remember that I have left out two resistors in the drawing in the video.

      Yes, it is possible with this design to build for all radio amateur bands.
      This mixer goes up to 500 MHz.
      The transistor in the transmitter is also a GHz transistor which will take all HF bands..
      One can also replace the oscillator with an SI5351 circuit.

    The transceiver is quite similar (although smaller) to those Chinese Pixie kits that are sold very cheap on e-Bay and Ali Express
    . They operate on 40m though, at about 500mW, and can work distances of several hundred kilometres.
    I wonder about the Morse key. Did you make it yourself? I'm glad that I could read LA5MT's Morse, as mine is rather rusty. ;-)

      He is using NVIS (Vertical Incidence) coms in the low HF bands, however there is little NVIS at 11m.
      The antenna would still work for ground wave, but is too low in height to be much use on 11m.

      I first write subtitles, then I export the texts as subtitle files. I transfer these files to AI generated audio on the internet. Then I cut up this audio and place it under the texts in the video.

    I'm sure I read in an article the OSS during WW2 told operatives to use fence wires for dipole aerials, they could be miles in length,
