Feed Notes
2021-09-16 Update:
I'm moving this to a set of digital/direct-sampled SDRs, eliminating annoying analog hums and distortion. This greatly improves audio quality, as well as allows me to better prioritize Rock traffic over Nobles. There may be some bumps as I tweak the config, but I'll minimize downtime as much as I can. Please let me know if you observe anything good or bad - RockCountyScanner@protonmail.com

Rock County utilizes the MN ARMER system. ARMER is a P25, Motorola, SmartZone, 800 MHz, phase 1, trunked radio system utilizing six zone controllers. ARMER provides approximately 95% state coverage.
This stream is currently being served by a Raspberry Pi 3b device, running Darkice, and a Griffin Technology iMic audio DAC. The RF receiver is a Uniden BCD325P2 with line-of-sight to an ARMER tower. Alpha tags are being read via a usb to serial interface to the radio, with the buffer being read and parsed by a small python script, which also assigns easier-to-read vanity names to common talkers. Upstream connectivity to the Internet is provided by a fiber backhaul to SDN. All equipment is running on APC SmartUPSs.
Now with ALPHA TAG SUPPORT! :) I'm still refactoring the code I'm using for this, so be patient, but it should be pretty consistent. You'll need to use a player that supports alpha tags, such as most phone apps (Scanner Radio, Broadcastify), as well as VLC, Winamp, iTunes, and the Java browser player, to name a few. Sadly, the HTML5 player doesn't appear to support them yet.
