Larry,

To get the total value of this modification requires the purchase 
of both 2.8kHz SSB filters (#754 & #755), plus the audio mod kit. 
Having installed both filters and the audio kit, the result is 
impressive - for ragchews and roundtables. For DX'ing, I still 
punch in the 2.1kHz (Inrad) or 1.8kHz (TT) filters to squeeze down 
the passband. Using a high quality external speaker makes a major 
difference.
