Ken and I will be accepting formal (paid) orders towards the next
production run of 700 Hz filters through 1600 UTC on Wednesday July 10th.
At that time we will commission production of batch four, and begin a
waiting list towards batch five.
See
http://www.unpcbs.com/frontdoor/
Since we have promised not commission another batch as long as anyone has
a filter they want to sell ... please contact me (off list) ASAP if you
have a 700 Hz filter surplus to your needs, and I will put you in contact
with the next person on our list.

If you are wondering what's so special about 700 Hz, then you might want
to check out our newest webpage, which features a slideshow that presents
a novel visual comparison of the five 8-pole CW filters. It uses an
analogy that likens bandwidth to the focal length of a camera lens, or
more specifically, to the resulting angular field of view for a given
focal length.
You may find that comparing the resulting images, is much more intuitive
than comparing a table of numbers (i.e. minus 6 dB bandwidths), or
comparing passband roll-off plots.
