Re: Dream DRM software "receiver"

It's simple software through and through. I'm using a high grade soundcard to maintain tilt and frequency response (echo AudioFire12, yes, overkill, but it was what i had around). SDR on the RX as i'm breaking spec to begin with, it's hard to even find a radio to receive DRM in native form, let alon...

Re: Dream DRM software "receiver"

I'm still looking into how the DRM synchronus mode works with AM. Apparently, much like AM stereo, it lives side-by-side in quadrature with the normal carrier. I have some software that can do it... Just gotta plug it in and find out how it really works. First i need an AM transmitter that can do I/...

Re: Dream DRM software "receiver"

Why the FCC hasn't looked at DRM? Simple answer, money. iBq was the only folks who provided the FCC with a "hybrid" solution. When i talked to the DRM folks down at NAB, they said it'd "never work in the US due to the frequencies being incompatible"... When i told them that we can just shove it in a...

Re: Dream DRM software "receiver"

To bring back a dead thread, i just decided to try this on my FM... as a subcarrier. So far, so good. Using Dream DRM as the encoder (run the app with a -t flag for transmit), set the offset to 67,000hz and voila! I have a DRM-based subcarrier being generated by a PC right into the SCA input on my 8...

Re: Optimod TV used to process FM audio?

You could always use a PC and some software, though i prefer the hardware method myself. For my experimentation stuff i used a program called "stereo tool" that can easily be set up to sound like top-shelf Orbans and Omnias. It does require a bit of horsepower and a sound card capable of 192kHz outp...
