[Elecraft] K2 SSB option performance penalty?

[Robert G Strickland]

Harry...

There is no CW performance penalty when the SSB option board is 
installed. The filter can be setup for CW independent of the SSB board 
filter when receiving. The K2 can be configured to use the K2 basic 
filter in a wide/ssb mode when receiving, but this is a less than an 
optimal setup. The SSB filter on the option board is optimized for SSB 
and is the filter that one would normally use for SSB reception. This 
selection is made in the filter setup menu that will reflect the 
presence of the SSB board. One can setup the stock K2 filter to provide 
a bandpass that is narrower than the filter on the SSB option board, and 
this might appeal to the operating style/ears of an individual user. I 
set up mine that way. However, while not operating SSB very much, I find 
that I hardly ever use the "narrow" filter so configured. I am virtually 
always using the SSB board filter for receiving. Others will no doubt 
say this more accurately/clearly, so wait till you get the full response.
