RTL-SDR Blog V4. The V4 swapped the R820T2 tuner for an R828D behind a built-in HF upconverter, so it needs the rtlsdrblog fork of librtlsdr -- the stock Osmocom one reports no supported devices. pkgs.rtl-sdr on this channel already is that fork (rtl-sdr-blog 1.3.5), so hardware.rtl-sdr's default package is correct as-is. That also blacklists the DVB-T drivers that otherwise grab the dongle on plug-in, and ships udev rules handing it to plugdev at 0660 -- hence plugdev in the user's groups, or every SDR app needs root. Apps: SDR++ and rtl_433; the rtl_* CLI tools come with the driver. Both SDR apps are overridden to drop hardware we do not own. SDR++ and rtl_433 default to supporting every radio ever made, which pulled in UHD (1.4 GB of USRP firmware), BladeRF and LimeSuite. gqrx was the original choice but reaches UHD through gr-osmosdr's gr-uhd feature; SDR++ uses no GNU Radio at all. Per-package overrides rather than a global overlay, so nothing else is affected. Bootloader: systemd-boot -> Limine, themed to match the Gruvbox icon theme. Limine installs to its own EFI directory and adds its own NVRAM entry, so systemd-boot stays on the ESP as a firmware-menu fallback. Display manager: lightdm -> SDDM with wayland.enable. Budgie in this channel ships only a Wayland session (labwc) and was already running as one; lightdm just handles that badly. SDDM's greeter runs on weston, not kwin, so no KDE compositor comes along. Qt defaults over Budgie's GTK/MATE apps. The Budgie module force-enables gnome-terminal and installs nemo, eom, pluma, atril, engrampa, mate-calc and mate-system-monitor; environment.budgie.excludePackages drops all of them in favour of konsole, dolphin, gwenview, kate, okular, ark, kcalc and plasma-systemmonitor. default-apps.nix rewritten to match: 113 associations, video to vlc, audio to elisa, text/code to kate, and /etc/xdg/xdg-terminals.list pointing at konsole. Fixes a real bug there -- inode/directory was mapped to gwenview, so folders opened in the image viewer. Hyprland-era leftovers removed. system-telemetry and weather-fetch fed Quickshell panels that no longer exist; brightness-ctl and hotspot-start lost their keybinds. jq went with weather-fetch. Also dropped gnome-screenshot, playerctl and imv. vault-toggle and strip-metadata stay -- they never depended on Hyprland. Comments trimmed throughout: deleted anything restating the code, kept the ones recording a why you cannot recover by reading it (systemd.gpt_auto, disable_ertm, ptrace_scope, the stable ethernet MAC, the mimeapps.list parser gotcha). system.nix went 225 -> 166 lines. README rewritten -- it still described Hyprland, Quickshell and Kitty. Screenshot dropped.
