AetherSDR — Open-Source Linux Client for Flex Radios

I have noticed this but this is the same with SmartSDR. Something to look at, What is your "DISPLAY" settings at for the "Rate" and "FPS" having these set at factory or to high can cause a lot of un needed network slow downs, for me I slow these settings down quite a bit from the Factory Defaults and it helps with the Network bandwidth required to run the Radio. I have my "FPS" at 10, "Average" at 15 to 20, and Waterfall "Rate" at 8

This is way easier on the eyes and not near the Network traffic.

Remember all this data needs to go over usually a 100Mb Ethernet port on the 6000 radios and most older computers and Ethernet Switch's.

Also on AetherSDR when it gets built you can change the bandwidth to "Low Bandwidth", this is in the "Setup", "Choose Radio / SmartSDR Setup" tab I think this will help a bunch of us with the OLDER computer hardware once it is implemented. This I think will really benefit many of us that use OLD computer hardware with the LINUX OS.

I ran a test Yesterday, I ran the AetherSDR Pi AppImage 0.7.2 on my Raspberry Pi 5 8Gig Ram. It ran surprisingly VERY WELL.

On the same Pi at the same time, I also run my Node-Red server and the FreeDV-FLEX AppImage while slice A was using FreeDVU on receive on my Linux Ubuntu Intel NUC6 AetherSDR.

This I think was a vary hard stress test for the Pi5 CPU at 77, Memory at 17, Temp 177*f, In comparisons with Node-Red server and FreeDV-Flexradio, and the Node-red server running at CPU at 30, Memory at 16, Temp 120*f.

Here is a screen grab and it was consonantly a "good" Network display so the Pi graphics are being handled very well.

It is supposed to run on a Pi4 too but I have not tested that yet, maybe tomorrow.

I think a very promising portable unit.

It's amazing how much power is available in the Raspberry Pi systems. My Anan G2 Saturn Ultra has a Raspberry Pi CM4 module in it. And it just cruises along with no real problems.

Of course PiHPSDR for the Anan radios is pretty light weight compared to Thetis. Or, probably compared to AetherSDR as well.

Is AetherSDR mature enough to work with the digital modes like FT8? After doing some Googling, I haven't come up with a working configuration. If I do a CAT Test that comes back green and I can change bands just fine. I have the radio set to "FlexRadio SmartSDR Slice A". I have audio input set to DAX Audio RX1 (FlexRadion Systems RX Audio). Putting WSJT-X into "Test PTT" puts the radio into XMIT, however it failes with a the "Test PTT" button coming back red after a second or two. I'm guessing there's something I'm not understanding about DAX, however I'm at a loss.

Any insight would be greatly appreciated.

73 and good DX,
