Hi Peter,

Thanks for your kind comments, and I hope you enjoy your new K2.

This is because the AOR data was taken in receive mode. The K2 phase 
noise data is from a transmit composite noise test. In transmit mode 
the noise floor is affected by a number of other factors, and the noise 
is generally worse than on receive.
