SDR Serials

For posterity:

SSH into Stratux and do:

pi@raspberrypi ~ $ sudo su -

root@raspberrypi:~# service stratux stop

[ ok ] Stopping Stratux ADS-B Receiver: stratux.

root@raspberrypi:~# rtl_eeprom -d 0 -s <String>:<Freq>:<PPM>

Where:

-d = Device number parameter

-s = String parameter

String = stx

Freq = Desired frequency assignment

PPM = calibrated PPM value

---

For example to set device 0 as the 978 SDR and set the PPM offset to 34 PPM enter:

root@raspberrypi:~# rtl_eeprom -d 0 -s stx:978:34

Note: SDR dongle must be power cycled for the changes to take affect.

After restart verify setting by invoking:

root@raspberrypi:~# rtl_eeprom -d 0 and root@raspberrypi:~# rtl_eeprom -d 1
