I can't help you with the one you recall. Because of your post I finally 
took the time to scan an article that appeared in the January 1990 issue 
of "73". Titled Poor Man's Service Monitor.  I would be willing to email 
a zip file of the images as an email attachment to anyone who wants it 
This also uses a scanner. Unfortunately unlike the tapr kit isn't self- 
calibrating.

There is this from  far circuits http://www.farcircuits.net/test1.htm
FM PACKET DEVIATION METER. $4.50. 73's May92. QRP EXPANDED LED READOUT 
VOLTMETER. $9.00. 73's Mar92. PULSED CRYSTAL SOURCE. $4.50. 73's Feb92 ...
