You can specify the rtl serial to be used in satnogs-setup → advanced → radio → SATNOGS_SOAPY_RX_DEVICE = driver=rtlsdr,serial=xxxxxxxxx

You can get the serial from rtl_test

pi@satnogs:~ $ rtl_test 
Found 2 device(s):
  0:  Realtek, RTL2838UHIDIR, SN: 00000002
  1:  Realtek, RTL2838UHIDIR, SN: 77022201

If the devices have the same serial number you can change it with rtl_eeprom

actually interesting topic for me as well…

assuming I have two SDRs:

  1. Airspy R2 connected to UHF antenna
  2. Airspy HF+Discovery connected to VHF antenna
  3. one Rotor

would it be possible to use to use both SDRs with the RPI satNOGS client and automatically use the correct one either if an VHF or UHF pass is scheduled?

Thanks, Peter
