Not a problem, garage is both heated and air conditioned.

SDR? Software Defined Radio? Acronyms aren't my strong suit.  Looks like 
the makings of a Spectrum Analyzer? If thats the case, I don't see 
dongle rx overload as much as a crappy src signal. OTOH, SA front ends 
are very susceptable to permanent damage that will show up like that.  
And the fix was a trip back to tek, accompanied by a check for 5G's or 
so in the 70's.

If you get that working so the keyboard/mouse can come in on the BT 
circuit of the pi, you might solve my problem with the pi as I 
understand that BT does not get funneled thru the usb2 pinhole to get 
into the pi.

Good luck with that, its interesting.
