    Thanks for the video and comments, Ron.

    I have been away for a few weeks, so just catching up on my Kiwi reading.

  • Search DX Cluster for recent spots in the right click context menu

    Thanks John. I don't think there is any rush unless someone is anxious out there. :)

    I have been thinking of other features to add to that menu.

    Personally, I would like to have adding a tag note as a menu item instead of just the shift-click. I tend to forget keyboard shortcuts :)

    Maybe we should add a menu item that shows a list of keyboard shortcuts or even more of a reference card to the UI.

    Another thought is to save the waterfall image to a file, but I would like to see the ability to annotate it and have an accurate time line stamped on it as well. I expect those are already on the long request list...

  • 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...

  • Caribbean Emergency Weather Net (CEWN)

    Amateur radio operators are providing emergency communications in the wake of Hurricane Maria.

    7.188 and 3.815 MHz LSB

    This is mainly health and welfare information - family members and friends asking about each other.

    At one point, I could hear both the Puerto Rican station and the US station who were having great difficulty hearing each other. Surprisingly there was no other ham on the frequency to help.

    I was listening via a Florida Kiwi, half way between the two. It strikes me that the availability of these receivers to ARES operators to assist in relaying messages would be important.

    If that did become the case, there would be a need for a priority operator to be able to kick casual listeners off in order to use a receiver. I am not sure if John has considered these kinds of protocols, but it may be time to start thinking about how that might work.

    The new propagation display on the VE3SUN list makes it easy to find stations with good propagation on the needed frequency. http://ve3sun.com/KiwiSDR/ but there are some bugs to iron out still :)

  • 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.
