[GreenKeys] Need a HAM RADIO correction,Oct 1976 issue

[Steve]

Hi Guys,
Ages ago I had a couple of boards made based on the article in the
Feb 1976 HAM RADIO magazine. Its the DT-600 RTTY TU/converter.
Finally got around to loading a board (!!!) only to discover it doesn't
work. A correction was printed in the Oct 1976 issue (short circuit column)
and a letter was published in the March 1976 issue. Of course I no
longer have these. If anyone out there has these corrections, sure could
use a copy. Thanks!
