When running a flow graph with vector sources that are reading a variable, does the vector source get
updated when the variable does? Or is there some other way of accomplishing this?
Thanks for any help

In a word, NEVER. No self respecting communication systems designer would

To me this doesn't make sense. The spectral bandwidth required is never a
function of the
samples per symbol (SPS); it's a function of

I am having a similar problem as mentioned by Moeller in his message. I have
made the required modifications to be USRP2 + DBSRX. All I see is a noise

Yes, the PFB clock recovery

Hi,:
I'm a newbie to GNURadio/USRP, I have checked the suggested reading at
http://gnuradio.org/redmine/wiki/gnuradio/SuggestedReading, but there're
a lot of material there, it would probably take a year to go through all
sections even if I just read one book from each section. I wonder if

I just plug the wbx to simple antennas, matched to the frequency you want
to transmit/receive.
And as Matt said, do not blow your board, don't connect tx to rx.

AM,
Call usrp2_probe to check if the board ID is 13 now. If it is still 2, the
burning had no effect.
I tried two times without success (didn't know that the ID would have to
change).
After another 3rd attempt later, I was successful.
Very strange. Every time I followed the instructions

Moeller has a very good tip here, we use different daughterboard id's

Testing the id number of your DBSRX on USRP2:
Thanks Jason, your diagnosis instructions are very clear now.
I thought it was more than just changing an ID number.
Can you add this to the official mod.-instructions on the gnuradio Wiki?
It would help people
