Hello Markus and Paul, group,

That's a much better explaination than Doppler shift. What would cause a
180 degree phase shift? Is there an XOR gate in the sky.

A few more dB will depend on getting some plastic machined. Hopefully
this will be before the end of winter.

The TX is off since ~10ut due to lightning in the forecast.
