More WSPR filter planning

Following up on my previous post.  I found another filter planning page - wa4dsy.net.  For this one, I put in data for a Lowpass filter, cutting off at 14MHZ.  It gave some plots of results.  I liked the Chebyshev plot the best.

Note, that the loss at 13.50mhz is only 0.2db.  The other plots showed 0.7.   Comparing the results to the calculatoredge.com page I found they were fairly similar.  Looking at inexpensive components on digi-key, I made the following comparison and decisions:

Calculator	Calculatoredge.com	wa4dsy.com	Plan
14 MHZ
L1	830nH	705nH	1.0uH
C1	299pF	253pF	270pF
C2	299pF	253pF	270pF

All of these components are available in 0603 package, and pretty cheap on DK.
