[Elecraft] Flaw in the 1.8khz roofing filter

[Dave Hachadorian]

I raised that question way back in January, purely in
response to the ARRL Review.

Since then I have bought two 1.8 KHz filters from Elecraft,
one for each of my K3's. Those filters perform very well in
contest service, with surprisingly good intelligibility.
Those are the filters I use all the time now on SSB.
