Reviving old thread.Changing the serial numbers of RTL-SDR receivers with EEPROM is quite easy with SDR Console V3.x:
1. Start receiving
2. Choose Home - Radio Configuration
3. In the Radio Configuration window choose EEPROM
4. Tap on Load to see the actual EEPROM content
5. Change the Serial as you like, but keep the 8 number format and don't use 000000xx,- instead sth. like 000001xx for your receiver no. xx (xx >= 01)
6. Tap on Save
Done.
I have two SDR-RTL v4 USB sticks and using your instructions I see they are both same serial numbers "RTLSDRBlog::Blog V4::00000001-1" so would i change that last number in the first string or the last number after the hyphen?
