Update: I’ve been extremely busy with the HackRF Blue project and have not had time to release an updated version of this image, but I will do once the HackRF Blue is out of the way!
This Raspberry Pi Image is built with rtl-sdr suite included for use with DVB-T dongles. You will need a 4Gb card (or larger) for this image.
System: Debian Wheezy armhf (Raspbian Wheezy) (Kernel 3.12.28+ #709)
Download the image and write to an SD card as you would for any other Raspberry Pi image.
Run raspi-config to expand the root partition.
Every DVB-T dongle has slight variances which affect frequency. Kalibrate is a tool that uses the GSM cell network to determine the offset of your dongle.
First, check what frequency the GSM network in your area uses, the options are: GSM850, GSM-R, GSM900, EGSM, DCS, PCS.
kal -s GSM900 //GSM900 where I live in Hong Kong, but yours may differ.
Then choose the strongest channel given in the results, for me it was 32.
kal -c 36
[-c channel of closest GSM station]
It will then give you the PPM offset of your dongle.
