Ultra-portable FT-8 Ops | (tr)uSDX + Android app + Audio Adapter = Awesomeness!

Published 2022-06-30
Want to run FT-8 from an Android phone? How about using a tiny 5-band HF rig that costs less than $100 for the kit? Now you can.

On this SOTA activation, I show off a few new pieces of gear and a new bit of software:
- A (tr)uSDX transceiver | amzn.to/3nskT85 (Affiliate Link)
- Custom Audio Adapter | oshpark.com/shared_projects/LwO6AYPS
- The "FT8 Radio" app | play.google.com/store/apps/details?id=com.bunzee.f…
- K6ARK SMA Antenna Matching Unit Kit | amzn.to/3nphvuK (Affiliate Link)

All put together, it makes for a decently capable little piece of kit. The (tr)uSDX has been getting a lot of hype lately, and it's an amazing little device for less than $100. But it's simple hardware, and perhaps not a fully optimized design. Understand that it's no high-performance radio. But it works. And in this activation, I demonstrate one cool way to put it to use.

I show off a new app developed by Dhiru Kholia. Although still a bit rough around the edges and quirky, it is fully capable of making FT8 contacts WITHOUT a separate linux or windows machine. For that, it's pretty dang cool.

And finally, I extracted the CW contacts I made on the activation and will publish them as a separate video (link here... once posted)

Thanks for watching!

    Adam you always blow me away with your minimalism.. real cool stuff, thanks for sharing.
  • @edvert1996
    I think you just made me want to get back into ham radio. I received my technician license six years ago, but didn't really find enjoyment, but now I might look at getting the general license and enjoying this little radio to get back into it... You are very encouraging!
  • @scottwood1143
    What a complete package you’ve assembled! Awesome work Adam, and great vid 😄
  • @jeff-73
    You are so kind to not only create videos but share your research down to the designs. Your picture should be included with the definition of the true spirit of HAM radio. I have learned soooooo much from you already. Thanks man.

    Hi Adam, greetings from the UK! Great video and lovely scenery. Glad I learned a few more things and tricks today. Thanks for sharing.
  • @alzeNL
    Very nice indeed ! I love how you actually explain the audio output and input.
  • @K1DTC
    Dude you blow my mind with these “gadgets” you make. Very well done sir.
  • @paulmower9102
    Very well done video. You have done a great job in explaining the TruSDX strengths and weaknesses in a well thought out way. I have enjoyed using my TruSDX for SOTA but have wondered about the distortion in SSB. You explained it simply in a couple sentences without beating up the radio, nice job. Paul, VA6MPM

  • @Lastaii
    That's a great combination -and a really inexpensive way to do portable FT8. Congrats!
  • Hey just caught you on a summit to summit today on W6/SD-026. What a coincidence I came home and chose your video to watch. I just got FT8 to work remote for me but it involves a laptop. I like your set up better.
  • @d3w4yn3
    This is mad, mad, mad genius!!! GLORIOUS!!!
  • @flipster7285
    Seems like someone will soon have to get a warehouse and factory to produce all the small little ham goodies 😉 great work Adam!
  • @davidedger8733
    Great video and interesting setup. The TruSDX was impressive. 73
