Re: Anyone want to go Radiosonde hunting?

HI Yes, launches seem to happen around 0715hrs/1915hrs or +15 minutes depending on air traffic from what I've seen. To track and chase I've used the radiosonde_auto_rx and chasemapper on a pi, but any Linux distro would work a laptop or NUC maybe. https://github.com/projecthorus/radiosonde_auto_rx T...

Anyone want to go Radiosonde hunting?

After lockdown obviously. Anyone interested in hunting and retrieving the radiosondes launched from Perth Airport twice a day? The trouble is the majority of them are currently landing in the bushland in the hills. Most of the roads near by are dirt roads and you'd need a 4x4 to access, and I don't ...

This is the NXDN4800 signal, that lines up with the my log files, however I'm not seeing any LRRP currently. https://web.acma.gov.au/rrl/licence_search.licence_lookup?pLICENCE_NO=1933525/1 Also in my logs I found a lot of position reports inside whiteman park, if I remember correct ...

Re: Anything in Perth that used LRRP

I have picked up something before, it appeared to be security cars. The reports were coming in quite regularly but for the life of me I can't find the signal again. I have a fuzzy memory that it was an NXDN4800 network, but could have been DMR. However I was monitoring the DMR station I thought it w...

Re: Swan taxi data channels

Sounds like it, to me it looks like some sort of high speed FSK. The low-high transition could be for frame sync.

Re: Pager Freqs

I found that PDW would only decode some pages, not all. It worked on Charles Gardiner hospital but didn't work on Vodafone. I ended up using multimon-ng under linux for 100% reliable decodes.

Swan taxi data channels

Hello all
I've been scanning around the band on my SDR and came across a data transmission from Swan taxis. I assume it's for those in car units they use. Has anyone written a decoder for it or aware of who makes the equipment or any docs on the signal standard? Thanks.
