CATS is a new comms and telemetry standard intended to surpass the current APRS standard by leveraging modern, super-cheap FSK transceivers
It does make a lot of sense as the more modern digital modes we’ve seen over ham radio, achieve the same with less bandwidth required, more accurate transmission, and better weak signal support.
It’s true though that APRS is very mature and widely supported through so many radios right now, so my big question is, how would this affect those radios? Will firmware update be possible, or will this work side-by-side with existing APRS? Luckily this is an open source type project so we won’t sit with the problem we’ve had with DRM, etc being proprietary.
My Kenwood TM-D710GA mobile rig is pretty expensive and not the sort of radio I’m just going to be able to replace (there is no other radio that does all that the Kenwood does).

Dieser moment, wo du den freund und vermieternachbar informierst, das du zu gerne heute deinen funkmast schon wieder aufgebaut hättest, aber nicht kannst .. weil für morgen nochmal sturmböen um 70km/h erwartet werden.
Und er dich dann zurĂĽckruft mit der info, das wir ganz dringend unbedingt das kinder-trampolin sichern mĂĽssen, weil das hat sich letztens schon bewegt....
Mkay na dann....... ich hab hier aus meinen heizexperimenten noch eine reichliche hand voll 10l kanister (ehmals ethanol als inhalt)..
Die haben schon seine hollywood schaukel vom davon fliegen bewahrt ..... wird auch fĂĽrs trampolin taugen. ;)

Hey everyone, I’m #newhere on this pod, though not on Diaspora, being on my third pod now. Like a number of other people I am a refugee from dapor.net. (Danke für die Zeit dort, Frank!) I’m interested in #baking, #bikes, #chinese, #hamradio, #japanese, #languages, #linguistics, #music and #taiwan. And possibly a few other things...
My web based OpenWebRx receiver has been upgraded to the Plus version with aircraft location data etc
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.
You can click on the very top bar where it says ZS1OSS Cape Town, South, and the bar will expand to reveal more information.
