The rig seems to work real well, has no scratches,
original boxes, manuals, spare (extra) parts, and
a rework eliminator kit (not installed).
It was built by me, with no problems during or
after the build.
The price is
Okay you techie gurus...please teach me
How does the composite TRANSMITTED phase noise impact the RECEIVE BDR specs?
I admit that over the decades I've frequently noted that the ARRL
review cite that the rx spec is phase noise limited but I never
thought that they meant XMIT phase noise.
WA6HHQ:
They are now making the dynamic range
measurements by measuring the on frequency IMD spur or blocked signal
using a narrow band spectrum analyzer. This separates the blocking or
IMD measurement from reciprocal mixing, which they will do as an
additional test.
I suppose this

The other thing all of us need to remember about
extremely close spaced measurements is that these are
made with continuous carriers (i.e. no key clicks) from
ultra-quiet sources (e.g. HP 8640Bs or quartz oscillators).
In the real world, nearby signals will have much more
And if you look at the actual phase noise plots the actual cross over
point is right about 5 kHz.
You are absolutely right about the importance of looking at the overall
area 'under the curve' for phase noise as you move out across the band.
The sum integrated total of the mixing of the phase
Here is what the sidetone really sounds like (using the handy TX TEST
feature of the K3 that disables output, but lets you oterwise
transmit):

It does sound good -- and different. It almost sounds like there's
some kind of phase difference between

If you integrate total world-wide TX phase noise and clicks on 20 m
now, then do it again after we've shipped our first two batches of K3s,
one would hope to see a healthy decrease.
Not to worry...I'm going to set up a company to sell phase
