I thought this was QRM but it looked like it had some structure on the spectrum.

The first one sounds familiar to some auto-alerting signal on digital channels within the maritime mobile bands (Sitor-channels). There are several digimodes that are able to wake up receiving stations with such a signal.

The second one sounds like some local QRM to me. Otherwise it could be a signal for some kind of measuring purposes. But I'm not sure about that.

Kind regards
