![]() Sony's entire circuit is an exercise in cost savings and I cannot recommend using any Sony ICF-XXX clock to accurately keep time. Someone else figured out that you can add the TCXO instead, though your results may vary. The best accuracy that can theoretically be achieved is ☒0ppm at room temperature (~10.34 minutes gained or lost/year), but with the temperature swings on the board it's going to be worse than that.Īn option which I haven't tried is to replace the XTAL with a DS3232 TCXO. There is an onboard crystal oscillator (part S3X1, X2 on the PCB schematic) supplying the 32.768K oscillations.

The alarm clock is a device that helps you wake up in the morning. ![]() You can't really fix this - I have the same clock and the problem is that Sony was too cheap to use a proper IC that tracks the time via the AC mains frequency (which power companies go to great pains to ensure averages exactly 50 or 60Hz over time).
