I got it!! :-)
The laptop is doing 0-30 mhz perfectly smooth...
This made my day. Thanks again!!

Glad to see you have it working Michael!

I still have my work cut out for me in terms of getting these machines into permanent positions, on battery backup, automated, VNC setup, etc... I need to make sure they basically take care of themselves.  And then of course, there's the "hooking them up" to the big antennas!  I'd love to get them fully online by next weekend. :-)

I'm stuck again. :-)  I'm trying to figure out a way so that when this machine starts up, it automatically starts up the SDR without me having to do anything.  I've tried adding it to "Startup Applications" a few different ways and that's just not working.  Any suggestions from the professionals?  :-)
(Right now it automatically logs in as me, and fires up Vino - I need to be able to have this machine take care of itself when I'm not around, OR we have a power outage which is common here).

UPDATE:  I am such a boob.  Typos are going to be the end of me!  That and remembering that Linux likes no mysteries and needs full paths.  LOL.  :-)
It's working!

Bas has some files for running this as a service. I'll repost those unless he wants to.

See sticky

Hi Machael,

Congrats on adding an RX-888 and NovaSDR to your website! I've been listening, from VLF through the HF bands and it is pulling in some great signals. LOL I just noticed I can go on mediumwave and hear WBZ (Boston) and WBAL (Baltimore) at high noon, at least on SAM mode and favoring one or the other sidebands.

Running the SDR as a systemd service ought to be the most reliable way to go, although it can seem a bit of a mess if you need to have prerequisites running first, or if you need to run some services as root and others as a regular user. With all of that sorted out, your Linux machine ought to run like clockwork.

I saw Bas shared some boot parameters to disable the desktop on boot, which should lighten the processing load and prevent the desktop and SDR having conflicts over the GPU. One way to have an easy way to just get the desktop when you want it is to set up a separate bootloader entry (assuming you are using Grub or something like it). One entry to boot and run with the desktop and a different entry to the menu containing the disabling code.
