Here’s a short and mainly visual explanation of my Dream DRM setup.
Here I’m using Dream version 1.12b. I have had trouble with the current (1.14) release crashing. For CAT control between Dream and PowerSDR you must make sure that your Dream has the HamLib included. Sound output is depending on the faad dll, AAC audio Codec file which is not included in the Dream package do to some rights issues.
You will need a Virtual Audio Cable (VAC) for passing the receiver spectrum from PowerSDR to Dream.
For CAT control you will need a set of Virtual COM Ports. Here I’m using the VSP Manager by K5FR.
