[TenTec] Filters

[Stan Gammons]

???  The 2.4 Khz filter I have is broken?   That's what I think. I 
wouldn't think -24 db for the peaks in the passband of the filter would 
be "normal"  The other filters were all around -15 db peaks in the 
passband.  I would post the frequency response graphs, but attachments 
are allowed on this group.
