Quality

[AD6XY]

I have heard a lot about the excellent performance of the new K3 in rejecting nearby interfering signals.

Great performance in the receiver is useless if the strong signal nearby is excessively wide. I hope to be that strong signal, so I hope I am not transmitting a wide signal.

I wonder how everyone else quantitatively tests the transmitted signal quality?

Is the 2-tone test unit used. What about phase noise. I can measure down to 70 dB below the wanted signal, but more than that is a challenge and yet it still matters very much to the listener adjacent if I am an S9+ signal. I think my signal is clean, but is it?

What does everyone else do?

If the phase noise is good on receive it will also be good on transmit.
The same synthesizer is used for both.
