Err, meaning spurs below -60dBc.

In addition to Joe's admonishment here, I note that the Si5351 spurs due to

be strong enough (~ -45dBc) to interfere with adjacent FT8 signals.
I'm not sure it's a good idea to use an Si5351 to generate a
I recently was puttering-around with an Si5351A and was reminded it is a
fractional-N synthesizer. One of the features of this is fairly prominent jitter

Well yes it's multi-threaded. Don't believe that's the underlying cause though.
Is there a common rig maybe?
So far we have 1 IC-7300.
Or a common OS?
Or a common 32/64-bit version?
For those that have seen this problem please repor

I'm seeing a crash - twice a moment ago - when W9YOY/M called me. Using 2.5.3.
Also running
JT-Alert for WSJT-X
Perhaps related?
