[Discuss-gnuradio] Compile gr_baz on OS X

2013-09-27 Thread Nigel Magnay 
Hi!

I have a shiny new USRP B200, for which I've successfully managed to get
working with gnuradio on a Mac by wrangling with homebrew and such.

What I haven't been able to do, is make use of gr_baz borIP - which I think
I need to run the HDSDR software (I have it up under Wine).

gnu-radio has compiled correctly, but the cmake generated gr-baz doesn't
seem to compile.

I suspect this might be to do with the c++ compiler being clang not gcc,
but I'm not sure (changing this didn't seem to help). It spits out the
error below, so I can't figure out how come gnuradio is happy with it, but
the gr_baz mod
ul
e is not
.
NB: I've compiled gnuradio to a version that's API compatible with gr_baz.


I'm not familiar with cmake enough to follow what I should be tweaking. I
appreciate this is a bit of a 3rd party software issue, but I wondered if
anyone else had any hints, as I'm pretty sure it must be something trivial.

TIA,

Nigel

As Jared said, the seed has to be a negative number:

Hi all,

I have an WA5VJB PCB Log Periodic Antenna including a SMA-F to SMA-M cable. I 
am using a N210 USRP and the SBX daughterboard. I have a second SMA-M/SMA-M 
cable.

How can I connect the Antenna to the Daughterboard / USRP ? Is there a way 
without soldering the included SMA cable to the antenna? I have also an SMA-M 
to SMA-M cable.

My intention was to connect the SMA-F/SMA-M cable to the daughterboard. Then I 
wanted to concatanate the second SMA-M/SMA-M cable to the first SMA-F/SMA-M 
cable. Finally, I wanted to connect the PCB Log Periodic antenna to the SMA-M / 
SMA-M cable via the connector (the small connector with the 4 legs).

I am afraid of making wrong terminations and to damage the Antenna ports. Also 
if I have to solder something onto the antenna, can anyone please explain how 
exactly I can do that?

Regards,
Dincer

Thank you Marcus,

but I have still the following questions:

Can I connect the Antenna then with the SMA-M/SMA-M cable to the daughterboard 
RX antenna port?

What kind of a stand should I use?

Can I put the Antenna onto the (plastic) GROUND PLANE (used against ESD)?

This is a bonus question:
Is it enough, that the antenna stands up? Does the SMA cable need to have a 
specific degree of bending?

I just re-did my tests with a pair of synched dongles, and instead of

That produced quite stable, near-perfect, correlation, once I adjusted 
the phase to peak up the correlator output.  This puzzles me greatly.

Cool.

I wrote up a few blog posts about the tests I did this week:

http://kaira.sgo.fi/2013/09/16-dual-channel-coherent-digital.html
http://kaira.sgo.fi/2013/09/passive-radar-with-16-dual-coherent.html

PS. I tried adding a third dongle to run with the same master clock. I
didn't do it correctly this time either by using an active signal splitter,
as that would increase the total cost :). I'll hopefully have some more to
report next week.

I was hoping to be able to have the same class deriving from both
gr_sync_block and QWidget, but unfortunately that doesn't seem
possible, but at least with this I can have both independently.

The downside is that it's harder to make the 3 versions of the block
share some of the code. I have a glfw version that's standalone and
doesn't depend on any GR gui toolkit support and I wanted to make a Qt
and WX version that integrated nicely and share as much as possible of
the GR integration code, but you need to do stuff so differently for
the 3 toolkits that's it's pretty hard to come up with a good
solution.

Yup of course.

I'd like to get WX to work as well so I know exactly all that needs to
be updated for it to all work together.

ESD mats are pretty crappy ground planes for RF purposes, great for not
damaging your hardware.  It's definitely safe to set it on the mat during
operation, though it will affect the beam pattern some, a metal bench
underneath the mat would affect the beam pattern much more significantly.

See the Wikipedia article on log periodic antenna to understand the beam
pattern.  Hint: point the small end in the direction you want to listen.

Does the SMA cable need to have a specific degree of bending?

There is a minimum bend radius, but generally just don't kink it.
