A little while ago SP6MR pointed out that Pi-Star now supports POCSAG, a pager standard. I know pagers are basically dead, but who cares, this is Amateur Radio!
So, after a couple of false starts with pagers bought off eBay that I couldn't modify, I bit the bullet and ordered a new pager from China 🇨🇳 which was suitable for use on the 70cm amateur radio band. Easy!
I'll spare you the details of getting it coded up, the software isn't great, only works on Windows, and the drivers aren't signed.
So, now I have a pager, it's registered on DAPNET, and my Pi-Star is too. I can send and receive pages!
What now?
Mastodon.Radio notifications!
Obviously (it's not obvious, is it?) I want to get notifications of things happening on Mastodon.Radio via my new pager!
The following code is hacked together, basic, has no error handling, and will break. Do not use it in production. It uses Python3 and is based on https://github.com/DL7FL/DAPNET/tree/master/DAPNET
You will need to setup an app on your mastodon server, and grab the access_token to put into your config file.
It uses the streaming API of Mastodon, so often the pager get's a notification faster than Tusky on my phone!

message = 'New ' + notification['type'] + ' from ' + notification['account']['acct']
print(message)
# Send it
dapnet.send(message, config['dapnet']['callsign_list'].split(','), config['dapnet']['username'], config['dapnet']['password'], config['dapnet']['serverURL'], config['dapnet']['txgroup'])
# Connect the listener to the stream

Like I said, entirely pointless, but maybe you find the idea amusing enough to try yourself? If you do, please light my pager up by sending me a toot! @[email protected]
