Granted I have only been using this radio two days (and am really enjoying it), but I can't for the life of me figure out how one cascades filters together.? ?In principle it is very clear what the end result should be, however, the manual does not explain (as far as I can find after one day of looking) how to do this.

?

Two filters of, say, 300Hz bandwidth, with differing center frequencies such that they overlap and create a filter that is not a narrow bandpass filter.? But?how?

?

CW Passband, CW Center Frequency, and CW Offset are the options with no apparent way to enable two filters with different center frequencies.? As far as the?Choose Filters option, they are all currently enabled for use.

?

If someone could clarify this procedure (with an example) I'd greatly appreciate it.

There are only two primary cw filters, 300Hz and 500Hz.? All of the other selections are the firmware cascading and sliding those two filters for you.? You enable the ones you want to see in the "choose filters" menu, then select in the desired filter in the "cw passband" menu.

There is a full explanation of this in Sec 5.8 of the operations manual.

Thanks Stan.? Actually those first two sentences are the lightbulb on how to use the filters!? Much appreciated.
