I featured my OpenWebRx receiver about a year or two back, which allows you to use any desktop or mobile browser, to be able to listen to various radio transmissions that are received at my home in Cape Town.
The previous version would allow you to tune into ham radio bulletins, repeaters, and simplex chats, including SSB on VHF and UHF, and even DMR and D-Star repeaters. It also had decoding for APRS location beaconing for vehicles, weather stations, etc.
By upgrading to the Plus version, my station is now also able to receive and decode the ADS-B locator beacons sent out by planes on 1.09 GHz. It looks like it is receiving up to a range of about 40 km. Not new to the Plus version, but I also added a profile for Cape Town International Airport’s Tower and Approach frequencies.
To view APRS or plane ADS-B beacons on a map, first open the correct profile (see red circle on attached image) and choose RTL-SDR Air ADS-B for the planes, or RTL-SDR 2m VHF Digital for the APRS beacons. Then, once they start to show data, click on the Map button at the far top right of the screen to view the map with those locations updated. In both cases, those profiles open on the correct frequencies ready to use.
Be aware though that up to 15 users can use this service, but everyone controls the same view. So, if you are listening to the plane beacons, someone else may switch it to APRS beacons and everyone sees the APRS view. And of course, if tow or three people try to control it, it could become chaotic. I may have to think about limiting it to one person at a time if the experience is not a good one.
