Hi all,
I am running DBSRX on USRP2. My laptop is Dell Vostro 1510, Intel
Core2 Duo 2.4GHz, 2GB Ram. Ubuntu 9.10 version 2.6.31-20. My installed
Gnuradio is version 3.2.2-1. Previously I have been able to use
BasicRX and able to listen to FM radio.
Currently I'm working on DBSRX. I have followed the wiki;
1) Remove R193 and put it on 194.
2) Burn the firmware `burn_dbsrx_eeprom.bin' and put it into USRP2
with DBSRX installed.
When I switched on USRP2, the following LEDS lit up: A, B, C, D & F.
Then I tried to search for USRP2 and it is not available. I switch off
USRP2 and burn `txrx.bin' onto the same SD card. I put it into USRP2
and I got LED D and F. I was able to run USRP2 FFT. I was able to see
the waveform. I tried to verify with my GSM 900MHz phone. I can't see
any activity on the FFT.
I'm using GRC, the USRP2 Source Decimation is 16, Frequency 935M. I
connect it to a FFT Sink with sample rate of 25M, FFT Size 1.024k. I
can see other signals. Is there anything/steps that I missed? Thank
you for your answers.
Regards,
Ahmad Zaki Yaacob
