September Birthdays: Ted Rotzoll 8th; Charles Daniels 17th, and Bob Krautstrunk 18th. Happy Birthday Shipmates! 4. Do you shop on Amazon? Remember to use Amazon Smile for the benefit of our Charitable Foundation. Donations through August totaled $3,865. 5. Giving back – Our base’s September meeting includes standing up the Nominating Committee for officer elections. Volunteers are needed both for the Nominating Committee as well as candidates for elected positions. In 2020, the officers to be elected include the Base Commander and Base Treasurer.

A radar operating at 1/100th the wavelength of an actual search radar will see a 1/100th scale model exactly as the real radar sees the full-size version. However, Page 3 Crash Dive Base Rondout - Lake Bluff, IL accurate 1/100th scale ship models that a new design is stealthy and is as currently take months to produce. close as possible to invisible to radar.

Models can easily be created from materials which accurately reproduce photographs, and by checking on the the effects of radar waves at longer desktop range it will be possible to find wavelengths.
