Just by accident I listened to the CW beacon on the Goonhilly WebSDR and seem(ed) to notice some short 'cracks' / ticks on the CW signal. These cracks/clicks are not related to the CW rhythm ('aka key clicks'). Also noticed this on the PSK-beacon.
To verify I listened with my own RX-setup and also heard these cracks/clicks. Sounds like there seems something (almost) 'loose' ...
<-- 'cracks'/clicks on the two long carriers
Edit: Don't seem to hear this with other signals.
