Demaw's Workbench column in Monitoring Times
 |
| December 1994 |
Any ham radio experimenter knows the name/call: Doug, W1FB. He was a much published author in various magazines, QST mostly but also in CQ magazine, sometimes SPRAT (journal of the GQRP club) and in Monitoring Times. While many of Doug's articles are only available via paid access the Monitoring Times column, Demaw's Workbench, is available on the ever wonderful Worldradiohistory site:
https://worldradiohistory.com/Monitoring-Times.htm
AFAIK the column started in August 1988 and ended December 1997 (Doug died in September of 1997). Here is a quick index to W1FB's articles (but you will probably end up downloading all the issues like I plan to :)
