[Elecraft] Spectrogram V5 - 2nd XFIL Flattening mod

[Dave Sergeant]

I downloaded Spectrogram V5.07 from the link given yesterday and can 
confirm it works just fine for setting up the K2 filters. I found my 
CW fitlers, aligned per the manual method, were virtually spot on, 
but the SSB settings were way off. Procedure very quick and easy to 
do.

Is there any advantage in doing the 2nd Filter Flattening mod if the 
SSB option (and hence the OPT1 SSB filter) is not fitted. Last time I 
looked into this it would seem it did little for the shape of the 
normal (CW) filters (which do look pretty ropey at the moment).
