Frequencies, times, and modes.  Bandwidths also.  Without that data the probability of an accurate identification goes down substantially.

The first is far too narrow to be anything like the Woodpecker.  Sure, the rate is about right, at roughly 10 Hz, but the rest of the signal is just wrong.  There are several possible answers, from XUP to pirate beacons, and a freq would help, along with what mode you used to receive it.

The second could also be any of several answers, but to me it sounds most like a spread spectrum frequency hopping signal than like the waterdrops jammer.  If you could tune across more than 10 kHz of frequency and still hear this signal the same it would almost certainly be SSFH.

I forgot I have a similar sounding station (to your second link) up on my YouTube channel.  In this case it is a 50 kHz wide SSFH signal on high VHF (UHF Mil air band).
