  • Repository of dx.json

    I have, as an experiment, imported the dx,min.json and the waszkd.json files into the list of transmitters for propagation forecasts to the online receivers.

    If google was able to determine a location from the comment field, you can click on the link to the list of KiwiSDRs that currently should have propagation to that transmitter. The propagation maps will be shown. You can then click on the SDR button to go to that receiver tuned to the frequency and mode.

    Work in progress...

    Edit: m0taz and dist.dx.json now added as well...

  • What do you "chase"

    Mostly I listen to the IBP beacons. 

    But since I have been playing around with the Kiwis I have stumbled across some SWL adventures that take me back to my earliest days. Hearing CHU again reminded me of my childhood days with a radio that glowed in the dark and had a green magic eye tube for signal strength - Hey maybe I should make one for the KiwiSDR! Nice to see that there are still some shortwave broadcasters out there.

    Hearing the NDBs reminds me of standing on the bow in the middle of the night as we sailed out of sight of land and pointing the hand held receiver around in hopes of getting a bearing on something to ensure we were heading in the right direction. 

    I think it is a time machine.

    It has also been fun hearing the DXpeditions, even though I don't have a transmitter on the air right now. Fun listening to those pileups from different locations and comparing propagation with the predictions.

  • A new Receiver list with sorting and station saving

    Thanks Martin.

    It really helps to know what users would like to see as we all have different interests and habits.

    You are thinking exactly on the lines that I am. I haven't quite figured out the best way to get there yet. One possibility is to incorporate the propagation into the map. Here is an example showing the propagation from/to John's receiver on 20 meters the other day. The hot spots are where the SNR should be best (absent solar flares).


    But that is a bit too complicated, maybe.

    The other option is to have a propagation table like this one that is already in DX Monitor, so easy to replicate:


    Both images based on VOACAP path analysis from the transmitter to the receiver.

    So many projects - so little time - which explains why this one has been on my mind for so many years.
