And not just for the K2. It turns out that all transmitter phase noise
plots published in QST going back for many years include a 7.5 dB error
in favor of the rigs. The lab has identified this error and corrected
it, so going forward we'll see more accurate numbers.
Much of the error is traceable to a decades-old HP application note
that, apparently, had been taken for gospel.
