D2d Info page question

I’m trying to determine the x-axis values on the D2d Info page. The numbers I have (and have seen in the documentation) are 47000.0. 47207.0 47414.0 47621.0 and 47828.0. I’m sure this is the frequency values, but was expecting the numbers to be in the 2.4GHz range, so I’m not sure what these values are, and I can’t find anything in the documentation that helps.

Thanks

It’s an arbitrary value and not actual output. The Herelink system is 2.4ghz.
