BTW: Getting PhantomSDR v.1.6.6 working on Fedora 41 with C++23 took a bit of 'head scratching'.
The script "install.sh" is for Debian variants, hacked that.
"subprojects/websocketpp-0.8.2/websocketpp/transport/asio/base.hpp"
Line 52 add:
#include <cstddef> // Required for std::byte   Alan1
#include <new>     // Required for placement new
Line 84 now replace:
    // lib::aligned_storage<size>::type m_storage;
    alignas(size) std::byte m_storage[sizeof(size)];


src/fft.h    "malloc" not defined
Line 22 add:
#include <fftw3.h>
#include <cstdlib>

And,
there's my SDR at a volunteer group "Men's Shed" which CAN decode FreeDV mode RADEv1.

shed.nepeanshed.org.au:8073

It took a bit of work getting "freedv-ka9q" to work, 8K stdin and stdout.

For comparison, PhantomSDR v.1.6.6 is released and running on 40m with a Mirics MSi2500 chipset SDR.

And KA9Q-web with the RX-888, same antenna, Delta loop and tuner

www.unixservice.com.au:9074

What I'd like to see here is, alongside FT8 mode, the FreeDV RADEv1 mode.

The newer and final version of PhantomSDR-Plus v.1.6.6 is already uploaded in Github https://github.com/sv1btl/PhantomSDR-Plus
New functions added and many minor fixes have done. There are also fresh documentation in folder /docs.

The installation project is almost fully automatic now. Recompile using a proper script, also saves a lot of time and painful work.

This is a final version, time for the developers to rest for a while. Every thing we suppose that would be useful for the End user is added, nothing newer comes in our mind for now, but we are open to suggestions.

Have a nice time trying to use the "older" PhantomSDR, which is maybe much newer...

Quote from: Phil AB9IL on Jan 08, 2026, 09:42 AMYour SDR has some excellent reception, from longwave ond through HF. I was checking out BBC 4 on 198 kHz, and it was coming in nicely to Croatia. There was too much noise to hear Algeria on 171 kHz, but I saw the carrier and have heard it at other times. That is all commentary on the RF side, but the interface is nice too!

The PhantomSDR+ (updated) interface was running nicely in Chromium and Firefox, using about 80 MB of memory. I was happy to increase the streaming buffer from a slider on the main panel, with no need to open another menu.

Yes,

SV1BTL has redesigned the user interface, now you can choose between four interface layouts!
When you arrive at the website, you are offered a default interface (as chosen by the administrator).

By simply clicking on the floating menu in the upper right, you can choose the
layout that suits you best at that moment.

Save this layout in a browser bookmark and on subsequent visits you will be
greeted by the layout you have chosen yourself.

Clicking on the band selection will automatically switch you to the
frequency that is popular in the part of the world where the receiver is located.

You can save what you want to listen to in a bookmark on the page itself,
the current layout of the page is saved, not just the frequency. 

If you want to record what you are listening to, you can,
you can download the recording to your computer,
the file name shows the date, time and frequency that was recorded...

If you prefer keyboard navigation instead of mouse, there is also...

Once you are on the website, you can temporarily turn off the waterfall,
then navigate using the markers that exist on all bands
(class nostalgia, the appearance of a radio receiver with a scale)

You can turn on or off the spectrum display,
regardless of whether the waterfall is on or off.

In the lower left corner, above the chat window,
there are additional filters that allow manipulation with
eliminating interference in the reception.

You can increase or decrease the buffer if you need to...

If you want to install PhantomSDR+ at home,
visit Github.

There you have detailed instructions on how to quickly, easily and without any hassle install PhantomSDR+.

SV1BTL has written advanced scripts that almost completely automate the installation process,
there is also a script with which you can recompile the backend or choose a different default interface (and much more).
