Hi,  Earlier I posted the following:

Does anyone have a copy of the July 1975 Popular Electronics Magazine?  
If so,  if it wouldn't be too much trouble, I'd like to get a scanned 
copy of an article:  "Compactron Frequency Calibrator" on page 75.

But I made a mistake in the year.  The year should have been 1962.  I'm 
still interested in the article.  The description of the article is:

"Compactron Frequency Calibrator," Popular Electronics , July 1962, P. 
75. By the legendary Herb S. Brier W9EGQ, this circuit uses a single 
6D10 triple triode to generate marker signals either every 100 KHz or 
every 10 KHz, depending on a switch setting. One triode section is used 
as a 100 KHz crystal oscillator, and the other two act as a 
multivibrator oscillator that modulates the 100 KHz output such that 10 
KHz heterodynes are generated as well, up through about 30 MHz.'

Thanks for looking.
