Accessing USB devices in .net core
Thanks for responding, I think I'll try installing it on my newly purchased RasPi 4. It has more beef in it.

Reducing size of fldigi display to fit small screen on raspberry pi
I am using raspberry pi zero w with success, however, it is oversized and I can't see the whole screen. Is there any quick and dirty way to reduce the display so it fits a 3.5 inch screen?

Downloaded fldigi from the raspberry pi site, it decodes PSK31 beautifully using the Signalink USB, but I cannot seem to get the TX function to PTT. Any thoughts???
