[Elecraft] K2 with 144Mhz transverter

[Eric Swartz - WA6HHQ, Elecraft]

Hi Adi,

There must be something wrong with your K2 or measurement set up. As can be seen 
from the phase noise plot on our web page (under radio comparisons) the K2 TX 
signal is better than -130 dBc when you get 10-20 kHz away from the carrier. 
Also, what b/w and span were you using on your 8590 analyzer?

On the receive side the XV and K2 pair are among the best out there. I do not 
know what was different about his set up.

73, Eric
