From 73d40374e770f79b501f69c905e30340dcea657d Mon Sep 17 00:00:00 2001 From: Marcus Kida Date: Fri, 10 Jul 2026 12:48:55 +0200 Subject: [PATCH] README: document on-radio channel add/delete; fix stale dim/7-seg notes Add a 'Managing channels on the radio' section and a feature bullet for channel create/delete. Update the screen-dim levels (now includes 15%) and drop the 'faintly-lit inactive segments' note (inactive 7-seg segments are now off).
