Yep - it just so happens that these are "digital" (P25) channels,
not analog ones, but robust detection/corre

While extended underruns are problematic, a short underrun should be

I have a USRP1 with a BasicTX daughterboard. When transmitting,
what is the proper method in a

Indeed you're right. Upon further research, I realised that nothing
throttles the Tx side but the USRP. So, according to my pre

everyone seems beyond knowledgeable. That being said, I have come to the
end of my recourses and am forced to pose a question. I hope this hasn't
already been answered, but I've been searching for a while, and
