Hi folks - I have an Omni VI+ on the way. I'm not clear on one thing. Are BOTH the 2.4 standard filters always cascaded together? If so, I guess that means you would have to buy a 2.8 filter for each board if you wanted to widen the SSB. Or can you cut out one filter and thus only need to buy one 2.8 for the 9Mhz board Thanks in advance. 73/Tim NZ7C
