Either we have more than one fast dasher with one also at 4097.1 or it's frequency is a bit unstable

It's kind of a mini-whooper itself, though I suspect it comes by that via a weak DC rail rather than FSK! :-)

Given the way it jumps around in frequency I'd agree that it is a defect

I suspect one fast dasher, and it is drifty in freq.

This ditter appears to have a slight chirp (down) on each pulse.  And the frequency drifts around, I have not watched it enough to find the limits or correlate time of day / temp / etc to the drift.
