Forgive me because I'm a software engineer with little theoretical comms
experience, but I'm having a difficult time understanding what a 180
phase shift at RF would mean for my baseband signal. If anything.
Now the issue is that with GRC, there's no way to use timed-commands
directly, so you

If I can ask a follow up here:
1) If I instead use 2 USRPs connected via an external reference clock
and an Ethernet switch for receiving data, will they be
phase-aligned? If I understand what's going on in the context of the
ref clock, I t

Hello,

One of the first things I'd like to see is if both receivers on the WBX

I'm having a problem with message ports. I am trying to have a separate
thread within within the block periodically post messages.
The block is defined as:

acars_GenAudio_x
acars
import acars
acars.GenAudio($rate,$rounding,$fake)
set_rate($rate)
set_rounding($rounding)

Hello,
The output of "lspci|grep -i ether" is:
*00:19.0 Ethernet controller: Intel Corporation Ethernet Connection I217-V*
*02:00.0 Ethernet controller: Qualcomm Atheros AR8161 Gigabit Ethernet (rev
10) (this is eth0)*
I am doing the following: *sudo ifconfig eth0 192.168.10.1 netmask
255.255.25
Also, the question is somewhat bifurcated. There are two aspects:
(a) Which parameters in the hardware end of things have advanced, and
at what rate, and what is considered "state of the art". This gets
broken down into a few sub-categories:
o ADC/DAC speeds
o FPGA gate-counts and speed
You probably will want to look at the papers published in this call for papers:

Sorry for my ignorance, I was only talking from my personal experience.

Cellphones made in the last 10+ years are all SDRs. Same thing for the
