The joys of radio!
There’s so many weird and wonderful sounds you can hear on the airwaves apart from voice transmissions including a vast amount of digital modes, one of these is DRM.
DRM stands for Digital Radio Mondiale, a digital radio format that claims to deliver FM comparable sound quality on bands below 30MHz.
Instead of me waffling on about DRM, more information can be found Here.
I decided to have a go at decoding a DRM signal using the SDRPlay RSP1 with the SDRUno software feeding the DREAM decoder software via a Virtual Audio Cable, the results can be seen in the short video below.
Hardware used with links:
SDRPlay RSP1:- www.sdrplay.com (any HF capable SDR will work) Dream DRM decoder:- https://sourceforge.net/projects/drm/ Virtual Audio Cables:- https://www.vb-audio.com/Cable/ VB Audio Cable is free to use but you will need to pay if you require more than one virtual cable. The other option is to use Virtual Audio Cable https://vac.muzychenko.net/en/index.htm (VAC is not free!)
