Re: Input RF switch fault found on TinySA ultra
I managed to change my lna and input switch with a tiny iron and Chipquick removal alloy. Doubtless, I was just lucky but it can be done that way.

Re: Auto Save Issues
Any input on how to save traces every 500 ms would be greatly appreciated. I've messed with all the settings to no avail. My best guess to to try to write a python program to tell the tinySA to save

Re: TinySA ULTRA 4" - No longer works
I meant to say: Can you push the jog button to the side (NOT down) WHILE RESTARTING the device?

Hi.
The situation you have is - honestly - a nightmare.
With so many clients in a mesh network you mess up a lot of theoretically available
