IMO, adding more words is not always better, Ian--unless one is getting
paid by the word! Adding to Ken Stewart's well-worded statement on page
11.9 in the ARRL Handbook hardly seems like gilding a lily. The
bottom-line is that rectifier "equalizer" resistors can CAUSE reverse
The puzzler is why did Mark Wilson and David Sumner publish 1200 words in
the 9/94 issue of *QST* which contradicts what Ken stated in the
Tom Rauch was right about old habits being slow to die.
