If you decide to set up an SDR for ADS-B, you might want to consider setting up a WebSDR with something like OpenWebRX. This would let people listen to all the signals in the bandwidth that you set.
If you’re interested, receiverbook.de is a list of most WebSDRs.
It automatically replies when it can read/summarize a site, but that isn’t always possible (maybe it has problems with some paywalls).
