No it cannot. The 2.4 kHz filter in the 580 is @~6.3 MHz. The 21x series filter on the Corsair's NB board is 9 Mhz. Also the 2.4 kHz filter in the 580 is integral to the IF amplifier board. So it is not one of the standard 28x series filters. The only 28x series filters in a 580 would be if you added either the 250 or 500 Hz CW filters.
