    Charlie! Thanks so much for the disassembly video. My CFT1 gets delivered tomorrow and I'm very excited to tackle it. I'm a new builder but I've assembled two QMX rigs over the last few months. This rig looks very straight forward. I recently did a video with Jonathan's paddle and I have his EFHW showing up with the rig as well. 73 de KI7QCF

    Appreciate the walkthrough, and then showing it off in the field. The tone is beautiful - seems like this radio could be used comfortably all day. So exciting to have a newcomer in the niche area of QRP kit design!

      Hi guys! I actually asked Ara to let you guys play with his at a SOTA activation sometime in the future! I'm curious to see what the SOTA cat's opinion is on this new radio!

    Great job Charlie! I like how you transcribe the code with errors and all. I do the same thing. Shows the viewers that we all make mistakes but just keep on rolling and nobody cares. Beautiful activation zone and looks like a great little radio.

    Hi Charlie, quick update. I have built my CFT1 now, and it’s had its first QSO. What an absolutely outstanding radio! I have done back to back testing with the obvious culprits and it by far the quietest sounding on RX, the audio is so smooth and buttery and makes picking out weak station very easy indeed. I could quite happily sit and listen to the CFT for hours (as I did this afternoon) without fatigue. There is a very good reason it is valued at a higher price, because in my opinion it is simply better, and well worth the extra. Kudos to Jonathan for producing such an excellent radio. 73, Lee M0VKR.

    Thanks for video. I wondered if the manual/instructions have a schematic? I was curious to know what the architecture is (superhet, DC, SDR?). I just like to know something about what I am building when it comes to kits. The CFT1 looks nice and sounds very nice on RX. The dedicated memory buttons are a nice feature.

      The manual has a schematic. There is also a high resolution schematic available for download as well on the documents page of ham gadgets.
      The radio is a superhet.

    • @JonathanKayne
      @JonathanKayne 2 місяці тому

      Unfortunately all of those features would require hardware changes to implement.
      SWR reading requires an SWR bridge, power output requires either an SWR bridge or similar circuit, and cw decoder requires an S meter.
      Also, I literally don't have any space on the firmware to add any more features so I can't really make them even if i wanted to!

    How well does the CFT1 tolerate high SWR. Am I going to blow the finals with an SWR of 3 on 17m? Same question, but could I use an autotuner (T1) and not risk the finals?

    • @JonathanKayne
      @JonathanKayne 3 місяці тому +1

      In our testing, the CFT1 handles high SWR extremely well. The advantage of using IRF510 in the finals is that they are incredibly overkill for QRP, so bad SWR isn't gonna be a problem.
      I also included over current protection so by the time the finals would be in danger the PTC fuse would have kicked in ages ago.

    • @e4949
      @e4949 3 місяці тому

      @@JonathanKayne Excellent. This gives the CFT1 a significant advantage over the QMX for both input voltage range and SWR tolerance. Add a 9:1 random wire and a T1 tuner for a perfect POTA kit.

      Even if you do manage to blow the IRF510, replacing it will not break the bank. About $2 and readily available.
      I wonder if the IRF510 is why the TX power drops off a little on the higher bands?

I've continued asking around and haven't gotten any definitive answers as far as stand out features, but the CFT-1 definitely seems to have a few fans already. I'd love to see a comparison video that really breaks down the differences. Good job on the CFT-1 video, anyhow.

    I've said it before and I'll say it again... You can get a fully assembled and tested, ready to play, QRP-Labs QMX for less than half the price of this
    - QMX is enclosed in Aluminum, looks and feels premium for a great price, can do digital(not that I'm into that mode), will be able to do SSB, built in SWR meter. It's an SDR, which means features can and have been added with simple software updates.
    - CFT1 Has a cheap & thick 3D printed enclosure that's not really a premium feel for that price point, has to be built(a QMX kit costs less than 1/3 the price if you want to build something), can only do CW, Does have better voltage tolerance(not a big deal for experienced users), and has memory buttons(😮worth the $200 extra), I can't imagine what he'll charge for assembled kits, $450-500?.
    This radio doesn't offer anything groundbreaking that justifies this high price point. This kit should really have cost no more than $100-150.

      Completely different designs though in terms of the radio side. I doubt you could do the crystal filters any cheaper.

    • @RedSummitRF
      @RedSummitRF  3 місяці тому +1

      I think most people have an open mind about new radio designs, and let things shake out a little before forming opinions. It's an incredible accomplishment to design and bring to market a radio at the age of 25. I've said it before and I'll say it again . . . value is measured differently from one individual to another. It's worth every penny to me.
