[Elecraft] Re: Unique synthesizer LO ? [additional data]

Peter,

I took a closer look at the AOR 7030 phase noise plot. Out to 5 kHz or 
so the K2 is noticeably better (11 dB better at 2 kHz). Farther out the 
7030 has the advantage. But remember that the 7030 measurements were 
made in receive mode, whereas the K2's were made in transmit mode, 
where all sources contribute to raise the noise floor. Hence the term 
"composite" used by QST in their product reviews.

         2kHz    4     6
K2      -115   -125  -128
7030    -104   -120  -128

73,
