[BC] DRM?

[Gary Peterson]

I've not been able to find the answer to my question elsewhere, so I am
coming to one of the best sources of collective knowlege, about radio, that
I am aware of.

On weekends, I have been noticing a broad signal around 7160 kHz that sounds
like a string-trimmer on steroids.  This frequency is often used by
international shortwave broadcast stations.  I'm wondering if there is a
station running DRM or if this is just a jammer.  Can anyone tell me what a
DRM signal sounds like on a product detector?  All I have been able to find
are audio files of properly demodulated DRM.

Thanks for any replies.  I'm very curious.

Gary, K?CX
