hi,
i was wondering whether the usrp can be used as a "gps receiver". if so,
1) how can i achieve this?
2) any link you could provide for me to read?
3) what daughterboards should be used?
4) Can the usrp be used with OpenGTS (for example) for tracking (usrp as
a gps receiver)?
thanks in adv
hi,
as some of you already know, i have a usrp1 with 2 rfx1800 burned to
rfx900, two small antenas (13db, 60 watts) and a stock clock of 64mhz
which i'm planning to change for the external clocktamer. however,
before i do that, i'd like to know which is the best option for me.
1) as i understand,
hi,
i'm about to buy the 52mhz clock and was wondering whether i need to
patch my gnuradio which is the git version (gnuradio + uhd).
according to what i've read, i have to create a file with the following:
"
diff --git a/usrp/host/lib/usrp_basic.cc b/usrp/host/lib/usrp_basic.cc

hi Josh,
thanks very much for your answer. i don't understand, if you added
redirects, why is my install not working? i got it from
www.sbrac.org/files/build-gnuradio
thanks in advance,

hi,
i'm now getting the following download error when trying to install
gnuradio + uhd from the git repository (build-gnuradio):

hi,
is it possible that there is something going on with the gnuradio + uhd
git repository web site?
i'm trying to reinstall build-gnuradio and have been waiting at:
"checking for package libxi-dev" for more than 2 hours.

hi,
i have 2 rfx 1800 and am using one of the tx/rx connections for the only
antenna i have. what is the difference between the tx/rx and the rx2
connection?
i understand it's a very basic question though would appreciate an
answer. thanks in advance,

hi ,
does anybody know what the reach of usrp1 is?
i'm using only one antennae and when i move the cell phone about 1 meter
away from the usrp1 it cannot register.
thanks,

Hi,
I'm trying to use usrp_probe. I type "usrp_probe" and then I have to
choose a unit number and daughterboard.
i have 2 rfx 1800.
questions:
1) which unit number should i input? what is the unit number?
2 which daughterboard should i choose (RX A, RX B, TX A, TX b)? does it
matter that i have

Hi,
I wanted to try connecting to a radio station and listening to it. Is
there a command for this? ... such as usrp_fft.py (which is for other
use), etc?
I have 2rfx1800 and the 64mhz stock clock.
Thanks in advance,
Walter

i forgot to mention that i'm using the 64MHz stock clock.

Hi,
i'm using usrp1 with 2 RFX1800. I write:
"
wbarmak@Linux:~/clock/kal-v0.4.1/src$ ./kal -s 1800
kal: Scanning for DCS-1800 base stations.
error: usrp_source::tune

What is this error? Having 2 RFX1800, should it detect DCS-1800?
Thanks in advance,

Good morning,
I have a USRP1 with 2 RFX1800, Ubuntu 11.04, Gnuradio 3.3.0 and
openbts2.6Mamou, stock clock (64MHz).
when I write:
usrp_fft.py -f 1800M
a flat spectrum appears. which I think is correct, but when I write:
usrp_siggen.py -f 1.8G
the command prompts:
Press Enter to quit
