• AI noise reduction. A new AI button with a strength slider sits under SQ in the Audio & Buffer panel (on the /mobile page, in the Audio tab under Squelch). It removes band noise from speech with RNNoise, a small neural network trained on voice — in the same spirit as RM Noise, but everything runs inside the listener's own browser: nothing is sent to an outside server, there is no account, and the receiver's CPU load does not change. The slider sets how strongly it works while someone is talking (default 50%); between words it works harder on its own. On a noisy SSB band the hiss between words drops by about 10 dB at 50% and by 20 dB or more at 100%, while the speech keeps its level, and the leftover hiss stays smooth; on weak stations the filter smooths its decisions more on its own. Voice modes only (USB, LSB, AM, SAM): in CW, FM, data modes and C-QUAM it steps aside, because the network treats a CW tone as noise. The decoders always get the audio from before it. See docs/USER_GUIDE.md under AI Noise Reduction.
• The QRG Sync button is now labelled TCI-CAT, after the protocol it speaks; it works as before.
• Four more receivers set up by the installer, on every supported Linux. The receiver question in install.sh (Debian and Ubuntu) and in install_fedora.sh, install_arch.sh and install_opensuse.sh now installs the complete driver chain for the SDRplay RSP1A (option 3, the open-source libmirisdr-5 driver with SoapyMiri), the RigExpert Fobos SDR (option 5, new, with two launchers: start-fobos-hf.sh for HF1/HF2 direct sampling 0-25 MHz and start-fobos.sh for the RF path) and the Airspy HF+ (option 6, new): SoapySDR, the driver, rx_sdr and a udev rule, so the start script runs without sudo. The HackRF One (option 7, new, with start-hackrf.sh) needs only the distribution's hackrf package and a udev rule; its example config now reads the HackRF's samples as signed (s8), as they are. Each receiver's part is also a script of its own — setup-rsp1a.sh, setup-fobos.sh, setup-airspyhf.sh, setup-hackrf.sh — that adds a receiver to a station already installed. start-rsp1a.sh keeps using SDRplay's own API where that is installed, so existing RSP1A stations carry on unchanged.

•     QRG Sync on the receiver page. A new QRG Sync button beside IF Filters lets the page follow your own transceiver by itself, with no desktop application: the browser talks straight to the TCI server of ExpertSDR, AetherSDR or Thetis on your computer. Frequency, mode and filter width follow in both directions — turn the rig's dial or press its FIL button and the receiver follows, click the waterfall or pick an IF filter and the rig follows — and the page falls silent while you transmit. On an Icom IC-7300 the IF filters select FIL1, FIL2 and FIL3 without ever changing the widths set on the radio. Rigs without TCI — the IC-7300 and most other CAT rigs Hamlib supports — work through a small bridge, tci-bridge/tci-rigctld.mjs, run next to the radio. Tested on an IC-7300. Full section, in all seven languages and in the offline PDFs: docs/RIG_CONTROL.md under QRG Sync on the receiver page.
•     Transceiver control from the desktop app. Desktop PhantomSDR+ 4.0 adds a Rig menu that keeps your own transceiver and a receiver window in step — frequency, mode and filter width, in either direction or both — and can mute the receiver while you transmit. Besides PhantomSDR-Plus it drives KiwiSDR, PA3FWM WebSDR and UberSDR receivers. It talks to Icom, Yaesu, Kenwood, Elecraft, FlexRadio and QRP Labs rigs directly, to every other rig through Hamlib, and to flrig. The receiver page gained the matching filter and mute functions in its CATsync API. Full manual, in all seven languages and in the offline PDFs: docs/RIG_CONTROL.md.
•     The CATsync Tool now hears back from the receiver. A waterfall click, a passband drag or a mode change reaches the rig in the tool's PA3FWM WebSDR mode, because the page reports its real frequency and mode the way a KiwiSDR does.
•     A 💾 Desktop applications button under Open Additional Info, beside System Resources, opens the download folder of Desktop PhantomSDR+ - https://www.dropbox.com/scl/fo/kjwj96zg3kj7dgq4fjef9/APnA3c9hhv4hk3YMGIGjH7s?rlkey=jfiwklly63kv73poalx631pk3&st=m37uvaym&e=1&dl=0
  ). The popup button row (VFO, Modes, Bands, IF Filters, QRG Sync) now has plain labels of one size.
•     Admin panel fixes. Clear Logs no longer fails with Permission denied on admin.log and proxy.log when the panel runs as systemd units, and the admin unit written by setup_admin.sh carries KillMode=process, so restarting the panel no longer takes the receiver off the air.
