Set your QS1R to 10.7 Mhz and the tuning will be done by the ICOM at 1427 Mhz. The bandwidth of the QS1R can be changed according to your requirement. This way whatever appears within the IF of the ICOM will be seen on the QS1R ( at 10.7 Mhz). Also remember you can only use the QS1R to tune across the bandwidth of the Icom I would suggest you get to grips with the QS1R as a standalone receiver and all its features within the software before using it as IF strip. You are aware of the point and click or drag the frequency bar to change frequency on the QS1R I take it. There is no digital round tuning knob for you to turn. Best of luck
