Sorry, I don't understand this point. The K2's I've tested fall down on LO
phase noise performance. Also note that the K2 measurements on the Sherwood
web site state that the receiver performance is limited by phase noise. I
agree the RX works very well, but I've attracted comments on the air (when
running QRO) re transmitted phase noise. Surely the good receive
performance is primarily due to having good selectivity near the front end.
Phase noise seems to be a taboo subject on here, attracting only personal
replies. Is there a way to bring it in line with other top rigs?

One of the features that gives the K2 receiver its 'edge' in hearing weak
signals over many of the other rigs is that the K2 does *not* use a
fully-synthesized local oscillator. With that superior receive performance
comes a trade-off: the K2 simply is not as stable as those other rigs with
fully-synthesized L.O.s in crystal ovens. Still, current K2's are very,
very
good, but it deserves a good 15-minute warm-up.
