Overrun Signal

aO is audio overrun, uO is USRP overrun…so what does OOOOOO…
suggest, a generic overrun?

Presents with the following:

UHD (USRP2) Sample Rate = 20M -> Rational Resampler at Decimation = 100
-> Throttle -> WX FFT Sample Rate = 200k

Trying to develop a setup with an FFT display for the available spectrum
to identify active channels and subsequent processing at ~100 kHz to
demod a channel.

for usrp2, uhd prints an O when it catches a sequence error due to
packet loss when the socket buffer is overflowed. BTW, the throttle
block cant be helping.
