the unit for testing! Would be curious to know if anyone else has
encountered a similar frequency error, or if the issue I saw was unique to
this particular example.
Fashinating error. Any details anywhere about how these are built?
A quick search came up with nothing.
Is this a FLL design?
There seems to be a somewhat caotic beat pattern in there, look how the
phase has relatively flat parts where it seems to be on-track, which
naturally is when it has it's high frequency periods near the 0 mark.
Links to the build?
Cheers,
Magnus
