[Skimmertalk] Flex and Skimmer : Decoded bandwidth ?

[Pete Smith N4ZR]

Hi Andy - my understanding is that the 24-KHz bandwidth is set in 
software by CW Skimmer.  I do not understand the technical rationale for 
this, but Alex apparently feels it is necessary.  That puzzles me 
because I just saw a Youtube video showing 192-KHz bandwidth running a 
Funcube Dongle Pro+ from the IF output of a TS-830, and EA6VQ is using 
one alone to cover 192 KHz of 6 meters for the RBN.

I know that VE2WU is (or was, I'm not sure) running a Skimmer/Flex 
combination on the RBN, and he reports coverage of 14000-14090. You 
might get in touch with him.
