My TinySA ultra device is giving me a "SI4468 Configure Fail" error and is not coming up. Any advice on how to recover ? Thanks Sridhar

I have a similar prob although not quite as bad, the rear of my 407 is the same as Andrew's except the serial # as expected. Mine also appears to be a little later as the serial # is greater. I've

Can you check if you see similar spurs at 1069 MHz, 2138 MHz and 4276 MHz? I assumed these where solved but if you still see them I have to do some more work. -- Designer of the tinySA For more info

*Thank you for the suggestion to create a dedicated group for WinSpectrum III.* Unfortunately, we don’t have the time required to maintain a separate support group. However, anyone interested in

Would it be possible to create a separate WinSpectrum support group on groups.io? No problem to point people to that separate group from here. -- Designer of the tinySA For more info go to

Hi, I'm beginning to use WinSpectrum III and I don't know how to switch inputs from the application. I works ok if I switch them in the tiny. Best regards, Ignacio -- Este correo electrónico ha
