That mod also fixes the problem that a lot of those generic Si5351A modules?are substantially off frequency. The branded Adafruit ones they are based on are generally closer. (Not illegal, by the way, the Adafruit design is open source hardware, you just have to remove the branding.)

Guys,
Why you will need this TCXO Module? No more noticeable drift,
even WSPR at full RF output! The TCXO is supplied by KDS of Japan.
The spec says 0.5ppm.
I am offering two options. Please add 5 USD for shipping each
order. PayPal to rongxh@... and leave your ship-to address.
I have 30 pcs in stock at this moment.

group, 4.9 USD each, 5 pcs max each order
- The reworked module on the right, will be made available to
public, 9.9 USD each, 5 pcs max each order
Thanks,
Adam
