Re: Merge multiple complex streams]

Thanks a lot, it really got me going! This is part of my learning
process,
if it’s leading to nothing at all; that’s okay.

Somewhere I red about feeding multiple dongles from a single signal
source, interesting…

A possible configuration:

  1. Upconverter & 30 Mhz low pass filter
  2. Cheap wideband amplifier / splitter ( 75 Ohm tv splitter ?)
  3. Rig dongles with usb hubs

I fiddled around with Mike’s example had a hard time to figure out the
way
to merge the FFT outputs. Found the solution in the ‘Streams to Vector
block’ Setting the vector length to the FFT size.
