Version 3.1.0 released

[Emmanuel SV1BTL]

Let us try to reinstall manually:

sudo apt update
sudo apt install -y \
    build-essential cmake git \
    python3 python3-pip \
    nodejs npm \
    aplay alsa-utils

Python packages:    
pip3 install websockets matplotlib torch numpy scipy

Verify Python packages:
python3 -c "import websockets, matplotlib, torch, numpy, scipy; print('All OK')"

Clone and Build the radae Repository (delete the previous ~radae -> rm -rf radae):
sudo apt install build-essential cmake git python3-pip
git clone https://github.com/drowe67/radae.git ~/radae
cd ~/radae
mkdir build && cd build
cmake ..
make -j$(nproc)

Verify lpcnet_demo was built:
ls -la ~/radae/build/src/lpcnet_demo

Verify model19_check3 weights are present (this is the correct model):
ls ~/radae/model19_check3/checkpoints/checkpoint_epoch_100.pth

Install Python Dependencies:
pip3 install websockets matplotlib torch numpy
pip3 install scipy

Verify the Decode Pipeline:
cd ~/radae
./inference.sh model19_check3/checkpoints/checkpoint_epoch_100.pth \
    wav/brian_g8sez.wav /dev/null \
    --rate_Fs --pilots --pilot_eq --eq_ls --cp 0.004 \
    --write_rx rx.f32 --auxdata
 
Wait for it to finish. It prints stats ending with:
loss: 0.741 Auxdata BER: 0.012

Then decode and play:
cat rx.f32 \
    | python3 radae_rxe.py --model_name model19_check3/checkpoints/checkpoint_epoch_100.pth \
    | ./build/src/lpcnet_demo -fargan-synthesis - - \
    | aplay -f S16_LE -r 16000


You should hear a voice. The output shows sync acquisition. The `underrun!!!` messages during this offline test are expected:
  1 state: search     ...
  5 state: sync       ... SNRdB:  4.03 uw_err: 0
Playing raw data 'stdin' : Signed 16 bit Little Endian, Rate 16000 Hz, Mono


Verify the sidecar starts correctly:
python3 ~/PhantomSDR-Plus/rade_helper.py

Expected output (no WARNING lines):
[RADE] helper starting on ws://0.0.0.0:8074
[RADE] radae_rx.py    : /home/sv1btl/radae/radae_rxe.py
[RADE] model          : /home/sv1btl/radae/model19_check3/checkpoints/checkpoint_epoch_100.pth
[RADE] lpcnet_demo    : /home/sv1btl/radae/build/src/lpcnet_demo
[RADE] auxdata        : ON (default)

[RADE] architecture   : per-connection (each user tunes independently)
[RADE] listening — waiting for PhantomSDR-Plus clients

I will try a full fresh install on an other server.

At this time, the ambulance is front the portal to bring me at the Psychiatric Hospital ....

More seriously

I have :

[RADE] sidecar starting at Fri, 10 Apr 2026 15:41:13 +0200
[RADE] helper starting on ws://0.0.0.0:8074
[RADE] radae_rx.py    : /home/f1nsk/radae/radae_rxe.py
[RADE] model          : /home/f1nsk/radae/model19_check3/checkpoints/checkpoint_epoch_100.pth
[RADE] lpcnet_demo    : /home/f1nsk/radae/build/src/lpcnet_demo
[RADE] auxdata        : ON (default)
[RADE] torch threads  : 1 per instance (RADE_TORCH_THREADS to override)
[RADE] architecture   : per-connection (each user tunes independently)
[RADE] listening — waiting for PhantomSDR-Plus clients

But don't work 

The most important, we solve the audio cut !

In a few time all my friends will be on W11 or Linux so i will switch on Opus.
Better sound and less latency.

Have a nice day Doctor !

Answer from AI:

everything is installed properly, without errors, rade.sh is running normally, 8074 is opened, but 'Sidecar not reachable. Start it on the server:python3 rade_helper.py  (listens on port 8074)" message appeared.

PM Diagnosed HTTPS/WebSocket protocol mismatch causing connectivity failureDiagnosed HTTPS/WebSocket protocol mismatch causing connectivity failure. This is almost certainly a mixed content block. Your PhantomSDR-Plus is served over https:// via Nginx/Certbot, so the browser refuses to open a plain ws:// connection to port 8074 — it requires wss://. The sidecar is running fine; the browser never even tries to connect.

Fix: proxy port 8074 through Nginx as wss://
Add this inside your existing server {} block in your Nginx config (the one that already has your SSL certificate):

nginxlocation /rade {
    proxy_pass        http://127.0.0.1:8074;
    proxy_http_version 1.1;
    proxy_set_header  Upgrade    $http_upgrade;
    proxy_set_header  Connection "upgrade";
    proxy_set_header  Host      $host;
    proxy_read_timeout 3600s;
}
bashsudo nginx -t && sudo nginx -s reload

Then in audio.js, find setRADEDecoding() and change the helper URI line:
js// Find:
var helperUri = uri || ('ws://' + window.location.hostname + ':8074');

// Change to:
var helperUri = uri || ('wss://' + window.location.host + '/rade');
Note wss:// (not ws://) — this goes through Nginx which holds the SSL certificate, so the browser accepts it.

Then rebuild:
cd ~/PhantomSDR-Plus
./recompile.sh

After this, port 8074 no longer needs to be reachable from the outside at all — traffic flows through your existing HTTPS port. The sidecar itself doesn't change, only the path the browser uses to reach it.

Please try this way and inform me about the results,

Nginx is not installed on the pc ....

[Emmanuel SV1BTL]

I can't add something more. It is installed in 2 more pc's that they are now working in Greece and even locally in a Pi5...

Can you please ask AI, becuse it will ask you questions and make some test, that I cannot make them my self in your pc ?
