[Elecraft] Anyone tried receiving DRM signals

[Tom Koeken]

Hi

Several broadcaststations are testing Digital Radio Mondial a.o. Deutsche Welle on 3995 kHz (yep allowed broadcastband in Region 1). 
DRM uses 12 kHz wide "audio" to be decoded by software into digital audio. 
A friend got it working op a TS-680? where he used a modified (wider) IF filter op a spare CW-N location in combination with the standard SSB detector/audio chain.

The IF-filter of a K2 is adjustable, but perhaps not wide enough for DRM. 
So my questions:
-has someone tried recieving DRM signals (and succeeded)?
-what is the maximum IF width fot the K2 IF?
