Really such a useful application. Wonderful - many thanks.
I am now planning / construct a AZ / EL Rotor.
Until now work with a Vetical. 
I only have one issue - I do not see anything in the waterfall -
(when I start fldigi also suddently I see sigs in the fldigi wartefall)
Have the FT991 - QRG / Doppler comp is runnig vy well. 
Have a Laptop wit WIN10 - screen res is 1366 x 768 only bur runs well.

Hi Erich,

The waterfall data comes from an SDR, regular transceivers cannot deliver 3 MHz of spectrum needed to cover the SAT band. SkyRoof supports a number of SDR models, some of them are very inexpensive. Please see the System Requirements section in User's Guide for a complete list.

Since we're on the subject of the waterfall and SDR, my Icom 910 has been modified to have a panadapter out - so, an RTL-SDR on 10.585 Mhz will see the spectrum.

Is this implementation able to be supported in SkyRoof?

SkyRoof does not support SDR on the IF of a transceiver, the SDR must be connected to an antenna.
