Re: LF: Software - a bit off-topic

[Dick Rollema <dickrollema@casema.nl>]

Dear John,

Thanks for providing this URL.  I used  to use a very old
program running under DOS for designing filters but the
AADE one looks like a very much better and improved tool. I also like the
tutorial which makes the program useful for those who want to learn a bit
about filters without  the need  for designing them.. 
Mike should certainly include this in his book.

(Upon opening the program a commercial for a LC-meter appears. Buit the
program  promises that after ten times it will not appear
again.
By the way the LC-meter is a very fine tool; I have one myself and am
very happy with it). 

73, Dick, PA0SE
