I have a new hackrf One and I can't get anything out of it. I am running Windows 10 (64 bit). I have it plugged into a USB port, it shows up in Device Manager. I ran the Zadig program to set the driver to WinUSB. I can see the device with hackrf_info, as follows:
C:\local\hackrf_tools>hackrf_info Found HackRF board. Board ID Number: 2 (HackRF One) Firmware Version: 2015.07.2 Part ID Number: 0x005d475a 0x005d475a Serial Number: 0x00000000 0x00000000 0x909864c8 0x343e0ecf and here is the output from hackrf_transfer: C:\local\hackrf_tools>hackrf_transfer -r rx_file -f 107700000 -n 100000000 call hackrf_sample_rate_set(10000000 Hz/10.000 MHz) call hackrf_baseband_filter_bandwidth_set(9000000 Hz/9.000 MHz) call hackrf_set_freq(107700000 Hz/107.700 MHz) samples_to_xfer 100000000/100Mio Stop with Ctrl-C 19.9 MiB / 1.001 sec = 19.9 MiB/second 19.9 MiB / 1.000 sec = 19.9 MiB/second 20.2 MiB / 1.001 sec = 20.2 MiB/second 19.9 MiB / 1.000 sec = 19.9 MiB/second 19.9 MiB / 1.000 sec = 19.9 MiB/second 20.2 MiB / 1.001 sec = 20.2 MiB/second 19.9 MiB / 1.000 sec = 19.9 MiB/second 19.9 MiB / 1.001 sec = 19.9 MiB/second 20.2 MiB / 1.001 sec = 20.2 MiB/second 19.9 MiB / 1.001 sec = 19.9 MiB/second Exiting... hackrf_is_streaming() result: HACKRF_ERROR_STREAMING_EXIT_CALLED (-1004) Total time: 10.00949 s hackrf_stop_rx() done hackrf_close() done hackrf_exit() done fclose(fd) done exit The rx LED came on while receiving. So far so good, but when I try to receive an FM broadcast (107.7 MHz) station with SDR#, I get: - static on the speakers - a big spike on the frequency display, but not much else; the spike goes away if I click on "Correct IQ" I also tuned to a ham narrowband FM frequency 147.42 MHz and then transmitted with my handheld. I could see an increase in the rf power, but still no audio (just static). Any suggestions welcome. Jake
