AREG is pleased to announce that we can finally open ports on our HF Remote receive site to the general public.
The AREG HF receive site, located ~100km north of Adelaide, in South Australia, is now operating a publicly accessible KiwiSDR 4 channel receiver. You can access the service from the following web address:
AREG wouldn’t have been able to make this possible without the support of Sam from Beam Internet who provide wireless internet access across the Barossa Valley and northern Adelaide Plains. Thanks team for your support of experimental Amateur Radio!
Using the KiwiSDR
For first time KiwiSDR users the following notes should be considered
- Windows: Firefox, Chrome & Edge work; IE does not work.
- Mac & Linux: Safari, Firefox, Chrome & Opera should work fine.
- Open and close the panels by using the circled arrows at the top right corner.
- You can click and/or drag almost anywhere on the page to change settings.
- Enter a numeric frequency in the box marked “kHz” at right.
- Or use the “select band” menu to jump to a pre-defined band.
- Use the zoom icons to control the waterfall span.
- Tune by clicking on the waterfall, spectrum or the cyan/red-colored station labels.
- Ctrl-shift or alt-shift click in the waterfall to lookup frequency in online databases.
- Control or option/alt click to page spectrum down and up in frequency.
- Adjust the “WF min” slider for best waterfall colors.
- See the Operating information page and Design review document for further information
A spectrograph provides a quick-look indication of HF band activity over a given time period. We produce a spectrograph covering three days of HF activity from one of our KiwiSDRs. This is updated every 10 minutes.
AREG continuously monitors the performance of the remote SDR site, comparing the median noise level to the upper 95th percentile level to produce a metric of Signal-to-Noise ratio, or SNR. The SNR can be observed to vary throughout the day as the HF propagation environment varies.
Over and above the equipment the club has purchased for this project, there are several members who have made a direct donation/loan of equipment or who have contributed directly to the development of the site. Special thanks goes to:
