Sub Receiver Filter Macros

Tony Fegan VE3QF
        I have been able to set filter macros on the main receiver but now wish
set the sub receiver filter macros. I have the sub receiver on and
linked (same frequency).

        I can set the main receiver filter with the macro:
k31;is 0550;fw0040;
        This works as expected (350-750 Hz).

        I now execute the macro:
k31;is$ 2000;fw$0100; (hoping to get 1500-2500 Hz)
        I end up with the center frequency of the main receiver shifted to 2.0
kHz and 1.0 kHz bandwidth set on the sub receiver. The "is$" does not
seem to work for the sub receiver. Is this correct? How should I set the
sub receiver shift?
        I suppose I could set the (sub) filter in "A", use the "SW" commands to
transfer to "B", and then set "A" again. It's a lot of shuffling but it
may work.

        Any suggestions would be appreciated. I need this to simulate a
"Contour" filter for SSB.
