Thanks Matt
I tried to change to get the external reference frequency to be 36 MHz, by
setting B to 50 (i.e. 0x32) and R to 36 (i.e. 0x24). To do this, I modified
lines 43 and 85 respectively to the following:
ad9510_write_reg(0x06, 0x32);
ad9510_write_reg(0x0C, 0x24);
However, when I rebuilt
Hi List,
I have been trying for a considerable amount of time now to build either 3.3.0
stable or

It seems I don't have all DPSK2 blocks installed. Where can i get them?

You need to be running the code from git; these blocks are not
available through the tarball releases.
If you have the source from git, you should have in

Hi list,
since pretty much all of my GNU Radio'ing consists of dealing with
out-of-tree modules I started a script to modify those.
In the current state, it can add blocks to an existing out-of-tree
module. It will attempt to guess a lot of stuff and then add skeleton
code for the blocks and the Q

Thanks, Tom! Sure, I think this may be useful to enough people to go

Hi everyone,
I use the UCLA ZigBee PHYsical Layer with gnuradio and USRP. And now I
try to increase the number of chips per symbol within the
Symbol-to-chips-table from 32 chips per 4 bit symbol to 64 chips.
I adopted the three files

Brain,
Thanks for the reply. We have tried terminating the antenna input, the spike
still shows up. We also tried tuning a bit away from the signal of interest and
mixing the signal of interest to baseband but it doesn't seem to help, the
spike
just follows the signal all over.
Thanks,
Nav

Hi all,
I am trying to use the convolutional encoder and Viterbi provided by the
gr-trellis class within another environment. I have my own mapper and de-mapper
blocks which I want to use. So I tried to use the feed the viterbi_combined
with this arguments:
va_combined =

Sorry my bad...your earlier technique worked. Thanks much

Glad you were able to get it figured out.

Hi Matt
I will try this, though given P = 2, I was under the impression the resulting
VCO frequency should have been 1 MHz * P * B = 100 MHz when I have B = 50. At
least, that is what the equation in the datasheet suggests.
Regards
Ian.

Hi Matt
Further to below, I tried your suggestion, and still it didn't work.
In fact, I have now found that the only thing that does work now is to use a
pre-compiled binary that I downloaded for txrx.bin (since recompiling with the
original gnuradio source code didn't work).
This suggests inde

Nonetheless, I still seem to get a time

thanks for your reply. My trellis is created like this:
t=trellis.fsm(1,2,[91,121])
The constraint length is 7 so it doesn't look like it was connected to a

do any truncating there before comparing the sou
