[GreenKeys] Sept 2025 Elektor magazine RTTY calibration Indicator

[Jim Pruitt]

Does anyone else take Elektor Electronics?  It is a Dutch or Belgium 
publication but with an English version.  I got my September issue 
yesterday.  It is the 2025 circuits issue (many small circuits rather 
than 3 or 4 major build articles).  On page 71 there is a circuit for a 
RTTY tuner indicator.  It is for tuning a terminal unit when you do not 
have a scope.  It is a circuit using 8 transistors (BC245C) and several 
resistors and a pot.  I was surprised to see this in that magazine.  It 
is one of the best magazines for the builder as it has many technical 
articles and usually pretty modern technology.  The article says this is 
from 40 years ago. Now I feel old.

Thank you.
