I am reading up on new technology that has come about since I left ham radio 
back in 1985. Interesting to read about using multiple filters and then 
controlling the bandwidth by "shifting" one filter's passband in regards to the 
other.
 
In the Omni-C filters are "cascaded" and (if I am correct) the bandwidth is the 
same as the narrowest filter.  I  have been thinking about getting a 500 Hz 
(400 Hz) CW filter while being well aware that the audio filters do an 
admirable job. 
 
Browsing the old Inrad website I find that there is a 1000 Hz filter. I wonder 
what the benefits of using such a filter could be in the Omni-C. (I am asking 
since I saw one posting in which the gentleman mentioned he was using a 1.8 Khz 
filter and the 500 Hz audio filter and thought that was about the perfect 
combination)
 
Many thanks in advance
Marinus,ZL2ML
