mine was a gilfer SWL special with 1.8, 2.3, 3 , 4, 6 filters

when I got mine I then bought the AUX-7 board and diode programmed it for
the SWBC bands. now it is a joy to operate. the few days I had it without
the board almost drove me crazy.


I'm running the 8, 6, 4, 3 and 2.3 kHz filters in the one I have here at
present.
