Has anyone attempted or had success in building a Dual Band Receiver?
My apologies if this has already been
covered. I did a search on the topic and found nothing.
Depends what you mean by “dual band”, but yes people regularly have a receivers on 1090 MHz and on 978 MHz feeding one RPi. Also might have a receiver on ACARS 130 MHz again feeding a single RPi. You just need individual SDR dongles tuned to those bands.
