FT-991/A Panadapter - Documentation and Instructions

These pictures and instructions are for Board Revision: N

This Wiki aims to document the PY2RAF's reinvent of G4HUP's (SK, RIP) Panadapter board, embedding a RTL-SDR in a FT-991/A Radio, using the radio's USB port to send the SDR traffic, with no extra cables, taps, chassis drill or IF ports, turning the FT-991/A into a real SDR.

Check the video for a glance of the final version working.
