AetherSDR — Open-Source Linux Client for Flex Radios

Hello all,

I have to give a huge thanks to developers of AetherSDR, they are doing a great job with software. At first I was a bit skeptical about behaviour of software but now I have to say that it works well on Linux and Mac.

However, I have 2 complains:

1. I can not hear my transmission on CW;
2. it seems not possible to listen audio from the radio itself.

Apart these 2 problems software is running very well and so my huge congratulations to developers.

Best 73 es tks all.

Wow, this thread is blowing up (in a good way)!

I got AetherSDR to compile without issue Linux Mint 22.1 and can run it. It is a whole lot easier than compiling a Linux kernel like I did 25 years ago.

I am trying to figure out how to connect remotely to the Flex 6400s in our Clubs station. I have the IP address and the Ethernet ports but can't figure out how to enter them into AetherSDR. I am a few revisions behind at this point and the problem may have been addressed. I may have to configure ufw to allow it to work but that is downstream of entering the network information.

I can build AetherSDR from source code. B,for whatever reason I cannot get the AppImage to extract in Linux Mint 22.1. I have about Googled until I am cross eyed ( which is hard to do being blind in on eye). If I try to extract the image I keep getting errors. I was hoping to give the image a try to seebif it solves the problem I have with switching back and forth between the pc speakers and the line level audio output for powered speakers on the back of the radio. I can switch between them once. And the next time I switch, the audio stops, the application freezes and then crashes. The log file doesn't show a reason for the crash. ( or not one that is obvious) This is using the latest version. And has been the same since the ability to switch between the two outputs was added.

once its executable, from the terminal you can "./AetherSDRxxx" (File name) to start the AppImage if you like the Terminal node.

In a terminal make sure you are in the same directory the file was Downloaded to and type in "chmod -x AetherSDR-v0.4.14-x86_64.AppImage" then do a ls -al and you should see if the mode for the file has the "x" in it. Now type "./AetherSDR-v0.4.14-x86_64.AppImage" for version 0.4.14"

hope this helps Tucker

Figured it out. I had to right click on the file and select Permissions, then Allow file to be run as a executable file. ( Google search is getting better)

Thanks for your help.

Hello all,

just to tell that my complains are solved, so a huge thanks, however, I can not control volume of sound from radio, it has the same value.

My best 73 es tks all.

@ten98 I just wanted to thank you for the fantastic work you are doing here with AetherSDR. I have been testing the latest Mac .dmg build and it is working very nicely.

I am mainly a CW operator (would quite like to be able to hide the decoder!) and my 8600 is located in my garage, connected by gigabit network to my office/shack. Normally I use my Maestro or SmartSDR-Mac for CW but they both only allow Opus encoded RX audio. But using AetherSDR has really highlighted the improved audio available for CW when the uncompressed floating point audio is streamed.

I realise you haven't yet implemented Opus encodce/decode, but when you do please leave in the option to use the uncompressed RX audio! When you listen to CW tones and compare Opus vs uncompressed its like having cotton wool removed from your ears. The CW is so clean. I have a decent pair of active monitor speakers that I use and when connected to the Maestro, CW is not too bad but CW tones sound sligtly distorted with noise modulation due to the Opus codec. The uncompressed audio in comparison is lovely to listen to!

I really hope Flex in the future can be persuaded to allow the option of using uncompressed RX audio with Maestro and SmartSDR, for those of us that don't have bandwidth restrictions to the radio. @Mike-VA3MW please :-)

73 and many thanks,

The new version of AetherSDR is VERY VERY nice and works well here on both Windows and Linux, and yes a BIG HATs off to Ten98 and the Crew for there AMAZING hard work on this project.

There are a few gotcha's but that is to be expected, some huge things that have been missing from Flex SmartSDR like on screen CW decode, having the Antenna Genius, DAX and CAT on the main window even though it is a bit different and CAT may not be compatible with all 3rd party software, the Windows DAX and CAT still operate if you run it on Windows OS.

Thanks to Ten98 for helping me when my UBUNTU Linux wouldn't compile the last few versions and he responded within a minute or 2 with the answer I needed and I got it Compiled with no errors.

Thank you for sharing your creation guys, it's something to be proud of accomplishing that has been asked for for 13 years.

Downloaded the latest version to my Linux Mint machine and to my Windows 11 machine. Both seem to work well. One thing I haven't seen is the ability to add another Panadapter. +RX just opens an additional Slice receiver in the same band. If accessing the radio from two different computers, in my case one Linux Mint machine and the other a Windows 11 machine, whichever machine starts up ssecond Shows the VFO control as VFO B instead of VFO A. Opposite the way SmartSDR handles it from two different computers running SmartSDR and accessing the same radio. ( unless being blind in one eye is causing me to miss something!)

With SmartSDR running on two different machines ( computers) and accessing my 2 SCU Flex 6600, each client will display VFO A for it's session. If I add a second Slice receiver it will show VFO B. It's like two radios sharing a single transmitter.

The other issue is I don't see a way to add a second ( or more depending on which Flex Radio is being used) Panadapter. A second ( or more) Panadapter ( spectrum and waterfall display) allows one to receive on two or more bands, at the same time depending on which model of Flex radio one is using. ( models with two SCU's can also assign a different antenna to each Panadapter)

I hope I have explained what I am asking clearly.
