SB-303 noise blanker

I was wracking my brains the past couple of days, because I swore I threw
that article in the SB303 manual. I have 2 SB303's, and two manuals, but
could not find that upgrade anywhere.
Found it this morning. I have the manual for the SBA-104-1 noise blanker,
and there was the article. It is QST for January of 1977...page 39.
By the way... It is one of those noise blankers that works very well...(like
Drake's)
Regards....Dave
