    Hi, Jim Thank you for the project video on WSPR , I am kind of late of this WSPR, I am be able to get this VFO-AD9850 worked, So do you have any info for the BPF on how to? anywhere or link?

    3:50 "...highest miles per watt..." A measure which completely ignores the inverse-square law. If I was awarded the "highest miles per watt", I'd send the award back, along with a copy of a Physics 101 text book. :-)

    Would it be possible to have this transmit on other data modes with custom messages, on different bands?
    ie say I wanted to do PSK or RTTY automatic message generation based on various inputs and received messages on 20m, to another home station?
    example would be GPS and other specific data.
    would really like to see something a bit more "customizable"; suppose I could crack open the code and see whats doing though. does WSPR use any sort of filters?

    • @jmhrvy1947
      @jmhrvy1947  6 ปีที่แล้ว +2

      Thanks for the question. Its a good one, This setup ( the hardware) could be programmed to generate most any kind of MFSK, or CW signal. But not PSK.
      How practical it would be as say, a RTTY beacon, I'm not sure.. 100 milliwatts on 40 meters using WSPR makes contacts all day long. But the same power using CW on 40 is futile. When comes to S/N, the WSPR protocol has a huge advantage over the asynchronous modes .
      As for the code in the sketch, yes please take a look, what you'll find is that 99 percent of it is about converting the text to be sent to WSPR. The 9850 takes very little code to output a given frequency.

    Hi Jim! Thanks for nice project! I'm trying to repeat, but i have found some problems in source code. I found Loop () routine strange.

    • @jmhrvy1947
      @jmhrvy1947  7 ปีที่แล้ว +1

      I need to know more about your setup before I can offer any suggestions. Are you using an SS micro (board type = micro)? If yes, then I would think the code should compile with out error.. But if it throwing errors , when compiled as a Micro, what is the line of code, and the error?
      Thanks,
      Jim (KW4KD)

    • @abrahamviselsson3310
      @abrahamviselsson3310 7 ปีที่แล้ว

      Yes, you are right. Problem solved by changing board type. First attempt to use Arduino Nano was failed, so, then i changed to Micro the transmitter have start working.

    • @jmhrvy1947
      @jmhrvy1947  7 ปีที่แล้ว

      Excellent! Good luck with your setup, BTW, don't be afraid to play with my value for time compensation ( msCorrection). That value is based on what my unit needed, and I find that it changes with temperature, Again good luck & 73.

      Thanks for comment. Probably should have done a better job, setting up the video.
      WSPR is the acronym for "Weak Signal Propagation Reporter"
      As the name suggests, people participating in this group are either
      listening for low power radio signals, or transmitting a signal (using WSPR protocol & designated frequencies)
      Most players do both (transmit and receive). But its not mandatory that you do. Anybody can operate/register a "listening" site, and I often operate just as listening/reporting site.
      I'm not sure about other parts of the world, but here in the US. the WSPR frequencies all lie in the "ham" bands. So to transmit, you need a valid amateur license.
      In this video, I'm trying to show that building a usable WSPR transmitter, is not that hard, or expensive. Hams love to try out different antenna configurations.
      and as indicated in the video, building two of these units would give you the means to do some direct A/B comparisons.
      Here are a couple of links that better explain what WSPR is:
      en.wikipedia.org/wiki/WSPR_(amateur_radio_software)
      wsprnet.org/drupal/
      On the wsprnet.org site, be sure to check out "Map" web page.
      Again, thanks for taking the time to post your comment
