Panadapter Yaesu FT-100 with RTLSDR + CAT control

I removed the 1st IF signal from the FT100 before the filter of this IF, at 68.985 MHz, where the band is still very wide, and we connected it to the RTL-SDR, thus obtaining a panoramic receiver, controllable both in HDSDR that FT100 via CAT (under development), and with a flat band higher than 2 MHz as seen in the spectrum in the following figure.
