            Look at the Ensemble RX schematic.
            Remove components connected to the 7474 CLK pin.
            Add components shown as R10, 11 and C3. Feed the Kees to C3.

              The SR40 is a single band XTAL controlled RX and the original Si570 Controller or current Controller II essentially implements  a VFO.

              I have not seen anyone mention using the 2 together but on face value the XTAL would have to be removed and the VFO used instead of it.

              I am not sure if it could be done by a simple substitution.

              Depending on which single band filter used, you would still have restricted coverage.

              The unit was meant to be used with the SR v6.3, Ensemble RXTX, RX II etc. replacing the ATTiny85 or with the SR63ng where it directly controls the Si570.

              If there is a Si570 on those boards, the one on the Si570 Controller is left off and the Si570 pads of the controller wired to the corresponding I2C pins on the Softrocks.

              On the page for the Si570 Controller there are links to Clifton Laborotories and notes in softrock40--> Files --> G3VBV which are quite lengthy but detailed to the point where I have had to closely follow them subsequently when building, installing and operating another Controller.
