  • @jks Thank you. Ok so will have to use the IQ data to get the Carrier Amplitude. Yes, to check if a AM transmitter is modulating well, Short-wave and MW, and not over modulating and causing splatter on band. Most AM Transmitters these days use as…
  • @jks Thank you. Ok so will have to use the IQ data to get the Carrier Amplitude along with trying to find a peak in the sidebands. Yes, to check if a AM transmitter is modulating well, Short-wave and MW, and not over modulating and causing splatte…
  • Things get a bit more complicated with modern AM Transmitters as they use asymmetrical modulation. So one can get up to 125% positive modulation. This is done to increase the loudness of the audio. And modern AM Transmitters also use Dynamic Carrie…
  • Hi John, Thank you. The equation 3 is what we would like to extract out of the recorded IQ data made by the kiwirecorder. Yes, this has to be before the AM Demodulator. As you say the AM Demodulator filters out the Ac - the Carrier Amplitude and fr…
  • Seem to be making some progress .. Thank you. I am using the kiwirecorder to record the IQ Data as a *.WAV file. Is there somewhere where the details on the structure of the IQ Data WAV stream is documented?
  • Thank you. Let me look at these. :)
  • I can confirm that Win 10 works the same as Linux. python kiwirecorder.py -s www -f 1440 -L -5000 -H 5000 --s-meter 10 RSSI: -67.7 And the single pipe command (>) overwrites the file each time: python kiwirecorder.py -s www -f 1440 -m iq -L -50…
  • Getting kiwirecorder to work on Windows 10. I hope these note may help someone. Sorry no pictures. The kiwirecorder is written in Python, so Python 2 must first be installed. Step 1 Install the latest version of Python 2 on Windows 10. Go to pyt…
  • Many thanks to jks and WA2ZKD. I now have Kiwirecorder working. I am sure there will be some more questions.
  • I now run ./kiwirecorder.py -h and get the help info :) Trying to work out how to connect to a kiwiSDR? Do you have a sample instruction line for me - just to do a 2 minutes audio recording? Thanks..
  • OK, I should have downloaded the whole zip file and not just kiwirecorder.py I am learning. Thanks
  • I would never have know about https://github.com/jks-prv/kiwiclient/tree/jks-v0.1 if you had now posted it here. Cannot seem to get to it from https://github.com/jks-prv
  • Now getting the error Failed to connect when I run ./kiwirecorder. Making progress. OK I see I may have installed the wrong mod_pywebsocket.
  • Hi, I have now found the kiwiworker.py file and added it to my directory. My directory is /Documents/KiwiSDR. I am running Ubuntu Desktop.
  • Now getting ImportError: No module named kiwiworker :( Help please.
  • I have downloaded the https://github.com/google/pywebsocket zip file. I have followed the instructions in the readme file.
  • How do I install mod_pywebsocket?
  • I am now installing numpy. sudo apt-get install python-numpy That has solved that error :) Now for the next error ImportError: No module named mod_pywebsocket :/
  • I am trying to run the kiwirecorder.py. I am getting the error import mumpy as np and ImportError: No module named numpy. Where do I find numpy.py?
