0.5ppm implemented in firmware?

[HowardZ]

Hi,

I am wondering if the K3's firmware has implemented the 0.5 ppm when
using the KTCXO3-1 1ppm High Stability Reference Oscillator?

Turns out our 1 PPM TXCO already hits 0.5 ppm from 10-50 C, which was
the original goal for firmware-assisted temp compensation. So such
compensation isn't necessary to hit that spec.

But in the spirit of making things as good as they can be, we're now
hoping to achieve 0.3 ppm with firmware assist. K3 Utility will soon
have a new screen for TCXO frequency/temp data entry. I will then have
a bit more firmware to write to make use of the data.

Thanks for your patience.
