XMLRPC in GRC 3.9

2020-10-07 Thread Marcus D. Leech
I've noticed that the XMLRPC implementation in GRC 3.9 is lacking the "logging" option in the block so there's no way to turn off the very-chatty logging that is normally done. In GRC 3.7 there was a"logging" parameter that you could turn off, and it was OFF by default.

Thank you. I have read this, it only shows the phase difference between two RX, how about the phase difference between TX and RX? Thank you. On Wed, Oct 7, 2020 at 4:31 PM Marcus D Leech wrote: > Google is your friend. > > > https://www.egr.msu.edu/classes/ece480/capstone/spring14/group02/docs/

Hi Chris, please, keep the walls intact and your brain operable. Hm, I've not looked too deeply into this, but: 2 Samples per symbol means that your bandwidth should be at least samplerate/2, and you've in fact got excess bandwidth. What does the frequency sink on transmitter side say? On the re
