We had the SMBV100 (full options loaded) on a demo for very few days and I
used it as a GPS simulator. The menus I have used didn't let me figure out
what kind of operating system was underneath...

EMU 0202 or 2020? I know what an 0202 is but what is a 2020?

I own a EMU0202 and when I use it with my laptop running on battery I
can see in spectrum lab FFT the DCF77 at 77.5KHz and the GB time-code
transmitter at 60KHz easily. The antenna is 1 meter of wire. Not bad for
100 bucks. I'm around 450km from DCF77 and maybe 800km from GB transmitter.

It was a typo, you guessed correctly. But it seem this is not the
interface you want and it may even be discontinued. I'm happy with my
Presonus interface box
Are you sure that a .WAV file can support the full MPX stereo and RDS
signal? I suspect that you need raw samples that a sound card can't handle.
The output of a FM stereo and RDS radio discriminator are beyond the usual
audio bandwidth. The output of the discriminator full bandwidth is first
used
I heard a broadband sound-card like EMU0202 should work.
I asked because of the various people on the list with expensive test
equipment one should be able to record a good sample.
Looks there is no interest.

Hi!
I'm looking for a sampled wave-file from a radio receiver MPX-signal
including the RDS frequency band around 57KHz. I searched the Net but
found just nothing that worked.
So I ask here. Maybe someone has the possibility to sample a couple of
seconds.
Thank you all!
