At the April monthly meeting of the Cascades Amateur Radio Society, a presentation was given by one of our members, Dave Foster (W3IGT), who is a retired geologist. Dave has been in the salt mines underneath Detroit! The title of the presentation was “Radio Rocks.”<\/p>\n
Sadly, Dave did not wear his Elvis impersonation suit for the presentation but the information he gave was very well organized and easy for the non-technical person to follow. He also included in the presentation information more tuned to the technically astute such as the nature of a given molecular structure. As a result, the presentation was very interesting for both the layman and scientist.<\/p>\n
In this presentation, Dave explained the historical development of crystals with respect to electromagnetic generation. This might otherwise be called…radios.<\/p>\n
Of particular interest is the vital role quartz crystals played in World War II. The War Department wisely decided in 1941 to make crystal technology development a priority. As a result, the outcome of Hitler’s Battle of the Bulge was turned back where it otherwise may not have been.<\/p>\n
Viewing time is 52 minutes of captivating information.<\/p>\n
