very important keep the technology !

Hello friend, I would like to know if you sell an .ova file of your virtual machine that contains the BTS server with openbts, asterisk and gnuradio ready to import into my virtual machine and connect my USRP

How accurate is the blood pressure measurement? I'd love to see it done concurrently with the standard armband/pump setups to see how close the results are.

hey man, what clock did u use for the usrp. i am recently having issues on replacing the clock on the usrp to 52 MHZ and i was wondering how u replaced the 64 MHZ clock with 52 MHZ thanks

What model glasses are those?

Right on Bro! Oh man I want to make one of these.... Would you perhaps be able to help me with the pattern / tab / note layout? I would appreciate it greatly! Well done and played fantastic! Cheers!!

mouse @ 1:49 ? or dustbunny.

how to read phone identity that connects to openBTS ( SIM number , oparators name)?

Awesome!

Did you have to buy the Daughter boards separately meaning if I only ordered the module itself I would not be able to plug and play. Or did it come with some default daughter board.

Help.......

?????????

Can u guy's shere me Vmware image...

I wish I had spare 700 bucks to buy it. lol

can we work with GNU radio on Mac OS

It is not possible to change the onboard 64 MHz clock chip. There are no pin compatible and physical compatible chips available. Your only choice is to use an external 52 MHz clock source. I purchased the 52 MHZ clock source to the specs that were provided by the USRP board manufacturer and created the piggyback board. Then found out that the given USRP specs were wrong and I wasted 8 weeks purchasing the wrong part. Bummer...

How did you manage to fix the 52 Mhz clock? In my case i purchased to a provider in China a lot of 52 MHz chip. Once installed on the usrp/wbx+gnuradio+kal i was able to scan and find many BTS antennas on all the gsm bands (850,900 1800 1900). My openbts start normally but my unlocked cellphones are not capable to find the test network. Finally i had to purchase the external clock generator from fairwaves. (Clocktamer) Please can you share the design of your PCB 52 MHz clock generator?

hi!.. I was wondering if its not possible to change 64Mhz cristall for an 52Mhz one inside USRP board.. did you try this?

Hi there, I have a question: Is it possible to establish a peer to peer GSM network by using a VPN to connect two separate USRP's in two different countries or two separate access points?
