shairport-sync VS gpredict

It's worth noting that shairport-sync exists. Perhaps it could be made easy by knitting some functions together?

You want SnapCast. You'd run snapserver on your Linux box and snapclient on your Pi's. Snapserver has support for Airplay (via shairport-sync) and Spotify (via librespot). I recommend using MPD for your music library, as I don't think PlexAmp can output audio in a way that's useful for snapserver.

I use shairport-sync for airplay (https://github.com/mikebrady/shairport-sync), complete instructions via: https://blog.adena.dev/blog/apple-airplay-on-raspberry-pi-in-7-easy-steps

If you’re interested, you might be able to get Airplay 1 & 2 support by running shairport-sync on your pi.

The plan is to run shairport-sync on the Omega 2 and have audio output to a 2x50w class d amplifier board.

To replace it, I've purchased in-ceiling speakers and a Control 4 Amp (C4-16AMP3-B) which I can control via the network. I plan on using shareport-sync for AirPlay and librespot for spotify as the sources to play music. 90% of the use for my whole home audio is for music.

ShairPort-Sync allows my Mac to listen for a AirPlay with multiple instances available, each pointing to different settings as per this GitHub Issue, which would allow me in theory to run multiple AirPort plugs and output each to an Alexa. Rarely would I ever need to have them playing all at once, and at this point I don't really care about maintaining pure audio quality or latency. I just need to be able to get out of my office and move to the kitchen, then back to my office without needing to spend a ridiculous amount of time trying to move what I was listening to on my iPad into my Echo Show

The benefit of the Pi is the open source software, in particular I use https://github.com/mikebrady/shairport-sync in order to turn it into an AirPlay 2 receiver, which I can stream to using my phone or laptop. It's my main way of sending audio to my hifi setup.

The only option I know of would be to use multiple raspberry pi’s running Shairport-Sync. I’ve been using the airplay 2 version for about a year and it works great. You might be able to build a server and run multiple instances of shairport with multiple audio cards. https://github.com/mikebrady/shairport-sync

So, after looking around, I realised that just like the Nest Hub 2nd gen, the Nest Audio also has a (sort of) exposed debug USB port. And these devices are (originally) running Linux. Since the Nest Hub 2nd gen has been jailbroken, I'm hoping that I can do the same on the Nest Audio, with a singular purpose: to inject a ShairPlay service, which would run parallel to the Chromecast services, which would allow me to use them as native AirPlay2 speakers.

I didn't watch the video but Gpredict has tracking and a map showing the orbit path and ground footprint for satellites you select.

I'm using sdrpp with Doppler correction with gPredict. I record the signal in sdrpp and then process it with noaa-apt.

look at the source of http://gpredict.oz9aec.net/

Your missing the point basically they mean upgrade your software to Gpredict satellite tracking software (GPL) which has Linux and Windoze versions. http://gpredict.oz9aec.net/   Gpredict uses hamlib to control both radios and mounts. Hamlib supports many radios and mount support includes Meade, Celestron and iOptron IEQ45 alt-az mounts via AUSCOM standard software. Once done the next part is ensuring you set up you com ports to appropriately control your devices radio and mount and making sure the appropriate devices are set-up in the software. Note if your com ports change say because you replug something, don't forget to update the port details otherwise coms will fail and the relevant device won't be usable. Check out the documentation and there are a number number of set-up videos on YouTube if needed.

LWN usually has great content but they've missed out on so much free ham software in this article that I use regularly.

My main HF rig is an older Yaesu FT-950. I tapped the IF and brought it out of the chassis where it is plugged into a cheap RTLSDR. I then access that RTLSDR (with free drivers) with GQRX (free software for visualizing anything compatible with SoapySDR or GNU radio), and the result is that I get a panadapter that is arguably better than what's available on $2000 radios.

As for VHF/UHF stuff, I would be hopeless if it wasn't for GPredict on my laptop making it simple to track LEO satellites. https://github.com/csete/gpredict Short video here: https://photos.app.goo.gl/eg87BWpt2XnJdGFp7

I also run an APRS igate, which is powered by direwolf: https://sielicki.github.io/posts/radio-scanner-aprs-igate/ , https://github.com/wb2osz/direwolf

It hasn't been updated in a couple years now, but `gpredict` is a nice desktop program that will show projections of satellite orbits and predict upcoming passes.
