[Xastir] Raspberry Pi with Xastir

[Ray Wells]

Fred,

On my adsb Pi I also bypassed the polyfuses that feed the USB ports and 
with a 5.0v supply those ports now see around 4.85v (I measured so many 
voltages on so many power supplies and Pi's that I can't really be sure 
of the exact measurement!)
