FT-991/A Panadapter - Documentation and Instructions

Pictures and instructions for the latest current revision, Light version, except when noted

Full Version board features and notes are included along documentation.

This is the documentation of the PY2RAF's respin of OE2DOR's Panadapter board, embedding a RTL-SDR in a FT-991/A Radio, using the radio's USB port to send the SDR data, 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.

While the project originally aimed to make everything contained inside the radio, there are also other build possibilities - Don't miss it, it is important for prototyping and early stages.
