25 ppm is 250 Hz at 10 MHz and 750 Hz at 30 MHz. That is good enough for a BC receiver, but really stretching it for an HF receiver.

An accuracy of 0.005% is what I'd call more than accurate enough for almost anyone on this forum, with the possible exception of those who actually use communication receivers for communications.

The Siglent has an external 10Mhz clock input that can be connected to an external source, such as a GPS disciplined oscillator, if higher accuracy/stability is needed.
