the Omni has space for 3 filters, the standard 2400 Hz SSB, a narrow 1800 Hz 
SSB, and  500 Hz CW.  I would like to instead use the standard SSB, a 500 Hz CW 
and  250 Hz CW in these three sockets.  Apparently need to equalize gain for 
the two CW filters.
What are you realy  trying to do?----- Original Message -----
