Thanks john , what i extracted from the information is that , in usrp the
baseband is is centered with IF as close to zero .. right.Is that the IF
conversion is same for all the frequencies and bands , and also how the ADC
sampling process reacts to the different data rate baseband data ...
Thanks

Thanks Marcus for your immediate reply. Now i have a DBSRX and WBX
Hi
I am using USRP2 and WBX with GRC. I have installed
txrx_wbx_raw_eth_20100608.bin on SD card.
Now I would like to use URRP2 with OPEN BTS.
I have connected external 10 MHz source to REF CLOCK and its working properly.
Is it necessary to use UHD for OPEN BTS project?
If yes, please guide me ...
I am looking at
http://lists.gnu.org/archive/html/discuss-gnuradio/
and cannot find the archives between those two dates: Jan 19 to Mar 31
any ideas?
thanks

I believe I managed to get UHD building properly, I'll post more details
when I know for sure (haven't fully tested yet). One thing I've run into
however is that the gnuradio configure script doesn't allow the uhd path to
be specified (ie --with-uhd[=PATH]). This should probably be fixed.

Marcus's libgruel instructions worked for me. Thanks for all your help -
now to begin hacking :)

I have already seen that and it is not exactly what I wanted/meant but
thank you.
I hope someone else has done/used something similar and help me.
Thanks in advance.

Yahia Tachwali,
If you send me your actual .grc or .py file, it will be easier to help
you, because I think you may have different sample rates set on
different blocks.
Also, are you cabling TX directly into RX?
Do you have any screen shots of the good and bad scenarios?

Hi Josh,
Is it possible to trigger storing data with pps using GRC I could nor
find a related email.
If so should that be included in FPGA or in software. A related work
would be great

Hello, dear community,
Does somebody know how to reconnect (self,0) of a Hierarchical block, after
call of disconnect_all()
Problem:::
The flowgraph with GRC looks as: gr_vector_source -> gr_multiply_const ->
Pad_Sink
For some reason I need to reconnect the gr_vector_source within my python
script
Performed the following routine:
commented all path lines from .bashrc. (I had previously tested it with
both dist-packages and site-packages).
ran sudo ldconfig

Hi all:
When I look at the code in the receive_path.py which is under the
digital-bert folder, I found this sentence:
self._snr_probe = gr.probe_mpsk_snr_c(10.0/symbol_rate)
I think this is to set the block which measure the snr of the signal. And

Hi everyone ,
I would like to know what is the actual last converted IF frequency which
is actually fed to the ADC in usrp/gnuradio , since ADC rate is 64MS/s , I
hope it IF should be less than 2xSampling rate of ADC, which implies IF
