Re: Calibration of the weather station

Folks, a small point in accuracy in terminology. _Altitude_ is what we pilots use to ensure our aircraft are always _above_ terrain and water! _Elevation_ is the term for measurement of a surface above (or below, in the case of Death Valley, for example) sea level. So, please replace all of the term...

The theoretical maximum is 480 Mbp/s on the USB controller. So 200Mbp/s for each of your two devices is about right. I don't know how many times I have to say this, but at least Dougie is now echoing that 480 Mbps is the _theoretical_ maximum bit rate, but it's also the _instantaneous_ rate, which ...
