Hi! I tried to use the recorded capture.bin of several arfcn with aiprobe. Checked the arfcn before with cell-log of osmocom. I converted the capture.bin to the cfile format with the rtl2832-cfile gnuradio block. checked the converted recordings with fft-gui of gnuradio. Seems to be fine. Now i used gsm-receiver with the follwing option to decode the broadcast traffic that is in ts0: GSM/airprobe/gsm-receiver/src/python$ ./go_usrp2.sh capture.cfile 174 0b with the downloaded samplefile of srlabs it works fine, but with mine not. i also tried to change the dezimation rate, did not help. i recorded the bin file with 1.8MS/s also did some tests with 200kS/s. How do i calculate the dezimation rate for the different MS/s ? I think it should work when i use 1.8MS/s and decimation rate of 174. What i am doing wrong? I am using the Hama Nano and the terratec noxon, both are working fine, tested it on radio-broadcast 88-108 MHz and 433 MHz ISM-Band. Will be thankful for any hint.
