DRM as Jamming?

There has been a report that DRM was being used by Ethiopia to jam VOA transmissions to that country.

I can certainly hear and see a wide-band signal there.

Is anyone able to confirm that this is some kind of DRM signal?

Check 9485, 9755, 11695, 11900, 12040, 12140 and 13765 at 1800.

Monitoring via Gavonata SDR 11/27

While there is a wide signal that looks like a DRM signal and sounds
digital, I could not get it to decode as a DRM signal.

I tried all the channels and found the jamming on 9755 and 12140 where there
did not appear to be a VOA signal. That way, there was no interference to the unid signal type. All this at 1840 UTC or so.
