RTL-SDR TCXO mod
- Desolder RTL-SDR xtal
/-----------\ | 1 3 | | 2 4 | +-----------/ (top view)
- Solder:
- 1 … +3.3V (can be found e.g. on the IR receiver)
- 2 … not connected
- For rtl-sdr that used the small rectangular oscillator:
- 3 … R820T pin 8 (the second in the second row)
- For rtl-sdr that used the 2-pin THT xtal
- 3 … the other pin than pin 8 that was connected to the xtal
- 4 … GND
- Enjoy your 0.5ppm experience!
- When used in constant temperature, the original oscillator and TCXO provide comparable performance (+/- 0.1 ppm over several hours).
- However, increasing the temperature from 28 to 48 °C means 0.14 ppm drift of the TCXO, but 3 ppm drift of the original oscillator.
