Turning FT-991A to a REAL SDR: Embedding a SDR Panadapter INSIDE the radio, no extra wires!
Channel: Rodrigo A B Freire
Date: 2019-08-27

This video demonstrates a working FT-991A radio with a Panadapter and SDR boards actually embedded INSIDE the radio, with no extra wires, no clumsy RF or band switches, holes in the chassis or FI cables coming outside of it. 

The SDR I/Q signal enters the radio's internal USB hub and comes through the existing USB port along the CAT and Audio signals to your computer.
