QMX firmware 1_00_017 AGC and S-meter demo

QMX multi-band multi-mode portable transceiver: qrp-labs.com/qmx In this video I demonstrate the action of the new AGC and S-meter features in firmware 1_00_017. For testing I generated an S9 30 (huge) signal using another nearby transceiver (PA disconnected, internal Synth active only). Without AGC the audio output of QMX is heavily overloaded and clips, generating distortion and some pain if ...

    • @QRPLabs
      @QRPLabs 3 дні тому

      It's for programming the code into the QMX+ microcontroller, for firmware development. All the STM dev boards have an "STLink2" programmer section and I'm using that connected to QMX+ for the code downloading. My QMX+ is "unlocked" so I can program it this way. All shipped QMX+ are locked, they have a bootloader and in the firmware update mode, the QMX+ appears on the PC as a USB Flash drive and you just drag in the new file.

    I just finished building my QMX+ about a month ago I bought at Hamvention last May. It went well (aside from a few swear words along the way...LOL!). I'm using a fixed 5x desk mounted magnifying glass, and I have a stereo microscope on a boom mount that can be positioned to allow work on fine detail if needed. I'm getting 3 to 5 watts output depending on the band. On to the next project: 2 QMX mini's I just ordered and received 80 - 20 and 20 - 10. It was a pleasure meeting you at Hamvention, Hans and working on these projects is a great way to escape the news circus/side show of nuttiness! Mike - ND7E

    The QMX line is already extremely capable. Really lovely rigs, excellent designs, excellent value for the money. If you can work your magic and get acceptable SSB performance out of it, it will be a near unbeatable kit for QRP, dollar for dollar!

  • @skrap1r0n

    Will SSB be an add on board for existing QMX+ units or will it be an entirely new architechture? I ask because I am looking to make a purchase of one of these in the next week or so and am wondering if I should wait.

    • @QRPLabs
      @QRPLabs 14 днів тому

      It's a firmware upgrade only, and applies to all existing QMX and QMX+. Note that the firmware for QMX and QMX+ is the same (some people missed this point).

    I just finished mine last night. I haven't tested it yet, but I applied power and it didn't let the magic smoke out so that's a win in my book. I had a moment of panic when I first powered it on and nothing happened, but I plugged it in to a PC and sure enough it showed up as a flash drive. I extracted and copied the firmware over and bam, it came to life! It's a great kit with very thorough instructions. I'll probably build another with the other bands in the future. Cheers!
