Closed stackprogramer closed 3 years ago

stackprogramer commented 7 years ago

Steps to reproduce

1.I had a HackRF one TX DVB-T,and a RX-DVBT with hackRF one, in receive it sucks ..... 2.with rtl-sdr and vlc it can received DVB-T signal........but with hackrf one sucks

Expected behaviour

after some research i guess that oscillator hackrf one is not accurate .it can should be calibrate? how we can calibrate hackrf one for different modulation....................

Actual behaviour

in real world i guess it can not calibrated in frequency.........

Version information

Operating system: debian os , gnuradio 3.7.12,linux why hackrf one not can received ? it has weakness in receiving? weak receiving can be related to ppm ? please help, any idea??? it can be related ADC?HackRFone has poor receiving why? i will soon share result. best regards stackprogramer

You can take a look at kalibrate-hackrf

Kalibrate, or kal, can scan for GSM base stations in a given frequency band and can use those GSM base >stations to calculate the local oscillator frequency offset.

@barto thanks it will try but we need a kalibrate for dvb-t and atsc.
