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!)

I by-passed the poly fuse on the power input and ran 5V directly to the USB
port pins. I don't know if that will help you but my RPi has been running
with an RTL2832 monitoring ADS-B for many months now.
Best regards,

Hi Ray,
I think you were spot on with achieving greater than 5.0 volts as you
mentioned in one of your earlier messages. I did some searching around,
and there are a couple of suppliers of power supplies that are rated at 5.2
or 5.25 volts that are specifically targeting the Raspberry Pi. I'm going
to try something with 5.1 or 5.2 volts and see if Dixprs and/or Xastir work
better in that scenario. That definitely seems to work well for you. I
suspect by running APRX I lightened the load on the CPU enough to get by
with a more marginal supply. Top never shows APRX using more than 0.3% of
the CPU.
