Digital Radio Mondial (DRM) on 6(3,5,7)000

I have been trying for sometime (months) to get DMR working on a 6500. Using the Dream s/w receiver (without the AAC decoder). Finally, found a quasi-strong signal from the BBC in the predawn hours that kicks in Dream DMR and decodes the program information. NOT having the AAC decoder Dream says "decoder not found". Does anyone have a DLL of this missing piece?
The Dream website has the source code but I'd just assume to not build it.
Questions about setting up the F-6K for DRM. I tried I/Q streams data but this did not seem to work. Using a DaX Rcv channel did. It was set to 24Ks/sec as was Dream. Mode was DIGU and filter width matched the transmission. Lock seems to drop out fairly easily, perhaps not surprsing with a SNR under 8. Are the F-6K settings correct?
In DIGx mode is there any difference in the Dax Rcv stream versus the DaX I/Q stream besides the bandwidth? I'd be inclined to say no.

You need this file
https://mega.co.nz/#!m5RUHIDQ!SqcGUBSGMFSTAm0qxx78RDYRoIJW0T545QQyRJ_dFuE
faad2_drm.dll
You can also try this dropbox link if the mega one doesn't work https://www.dropbox.com/s/85xw3erhcvlh2z6/faad2_drm.dll?dl=0
SETTINGS that work for me
Settings > Sound Card > Signal Input > Device > Dax Audio RX1
Settings > Sound Card > Signal Input > Channel > L + R
Settings > Sound Card > Signal Input > Sample Rate > 48000 Hz1 -
Also, here is a video with those settings receiving a New Zealand DRM station with a Signal of 5 from Barbados.
For the file above to work make sure to just place it in the same folder as the DREAM executable.1 -
Maybe one day it will be a WAVEFORM plug-in that you could download from flex?

This is very helpful! A big thanks...
Now to get up at the **** of dawn and give it a go.
A waveform may be problematic due to the license unless users pony up. One problem is there doesn't seem to be many DMR stations stateside at a decent hour.
Many Thanks,
