ARRL HANDBOOK FILTER DESIGN TABLE IS INCORRECT. The information on CWAZ  50 ohm low pass filters Table 12-8 on page 12.37 of the 2006 and 2007 Handbooks is wrong.  The correct information was published in the February 1999 QST . The  ARRL has given us permission to print a corrected table.  Just email pastimeprojects@yahoo.com and ask for the filter letter. The letter is in word format.  Please tell your fellow club members.  Glenn NN8G
