If recent published info is correct, this specifies a bandwidth of 6hz why is USB with a bandwidth of 3 khz necessary to receive this transmission.
Surely it would be obvious that CW mode was more appropriate where one could use a narrow filter and dsp processor of a few hertz.
I have asked this question before but never got an answer.
