While I have not seen the discussed in band CW and FT8 RX/TX design, it is an entirely different problem to have 2 narrow slices that don't move in band vs having 2 TX/RX stations that need to operate on any set of frequencies of the entire CW or SSB portion of a band.
5khz and 3 khz separated by 50khz is the challenge required by the described DXpedition issue. And you can insure those slots never change after design. Ed N1UR _________________ Searchable Archives: http://www.contesting.com/_topband - Topband Reflector
