Hi all
Trying to get frequency hopping on gnuradio 3.7 and
https://github.com/BogdanDIA/airprobe-hopping
The build goes fine but when I try to run ./capture_decode I get the
following.
./capture_decode_channelize2.sh
min_ARFCN: 18
max_ARFCN: 25
Center ARFCN: 21
Center frequency: 939200000khz
Sampling rate: 464286
Number of samples: 256000000
CA files: out/out_18.cf out/out_21.cf out/out_22.cf out/out_23.cf
out/out_24.cf out/out_25.cf
C0 ARFCN: 18
C0 position: 0
SR: 464286
NCHANNELS: 50
pfbDECIM: 17
totDECIM: 112

I am trying this with USRP1 and my clock frequency is changed to 52mhz.
Can someone please tell me what need to change.
