Hi,
I'm new to this list. Need some help compiling gnuradio 3.0.1 in Ubuntu

There is no problem using these antennas with your board, as long as you
terminate them correctly, 50 O.
You choose your antenna based on your coverage, not your board. So what

IQ files are binary files with the raw stream and no headers. Depending on
sample resolution, these are complex pairs of either floats or bytes.
Conversion of bytes to floats is given by the code:
float f;
byte b;
f = (b - 127)/128;

Hi,
I missed your second part. gr-fosphor is realtime, so It will follow
whatever frequencies you have. Frequency hops show as frequency bands in a
frequency spectrum.
The frequency spread of a single plot, is your sampling frequency.

Indeed, there is phone locator protocol, and a service offered as by some
companies. They work through provider contracts. The problem is that you
have to know the phone number beforehand and the carrier. Not very useful

You can attach gdb to whatever process you choose. Indeed gdb is the

In a Unix system to locate libboost.so you can type:

Just to update you.
It seems that the repository has gnuradio >= 3.0. It is impossible to tell
in those old revisions the version number (no cmake, no git tags) but
getting the earliest revision from 3/2006, I came across a Changelog with
entries since 7/2006! Go figure! The changeover to 3.0 given
outdated version, well OK,
just for finding it, but also while I asked for onoy 1 of 2 options in
locating it, I was offered both ;-)
Please hear my advise. Developers should support the "gnuradio -v" option
and use an include file to do it.
In a few years git will be superseded by another v
