[Elecraft] [K3] Perfect for Field Day S&P ... Limited Production 700 Hz 8-Pole Filters

[Amateur Radio Operator N5GE]

The advertisements for that particular brand of 700Hz filter are
passed through my junk filter or I wouldn't have seen it.

I'm surprised you didn't delete the entire advertisement.  I guess
I'm going have to add the phrase "limited production" to my filters.

In the K3, as it comes from the factory you already have a 700Hz
filter with the standard 2.7 or 2.8 filter.  Just use the width
control to set either of them to 700Hz.  It may not have the same
slop as the 700Hz filter in question, but when you are listening wide
on the sub RX in the K3 the difference between 700hz and 1Khzis not
that much.

I use a 1K filter to listen to to the pileup and a 200Hz filter to
listen to the DX.
