DIGITAL LIBRARY OF HAM RADIO EXPANDS COLLECTION

STEPHEN/ANCHOR: The numbers just keep growing into the tens of thousands 
in the Internet Archive's Digital Library of Amateur Radio And
Communications. Jack Parker, W8ISH, gives us those details.

JACK: It's a virtual bookshelf of radio that seems to go on into infinity: 
The addition of new documents from the Anchorage Amateur Radio Club in 
Alaska, the Worldwide TV-FM DX Association, the Irish Radio Transmitters 
Society and the Pikes Peak Radio Amateur Association in Colorado has 
expanded a digital collection of shortwave and amateur radio history to 
more than 75,000 items. This is the work-in-progress known as the DLARC 
Radio Library. The library also contains more than two dozen episodes of 
the RAIN Report that were believed to have been lost. Yes, you will also 
find archived newscasts from Amateur Radio Newsline.

Program manager of special collections Kay Savetz, K6KJN, said the most 
recent additions include recorded presentations and talks, including those 
from the MicroHams Digital Conference and the Radio Amateur Training 
Planning and Activities Committee, known as RATPAC. The library is 
especially pleased to have added episodes of International Radio Report 
dating back 23 years. The collection also features Continent of Media, 
which focuses on the range of media throughout the American Continent.

Many amateur clubs' newsletters which were never posted online before are 
now available and are full text-searchable and available for download. The 
library, which was created with a grant from Amateur Radio Digital 
Communications, is always looking for new material to add to the 
collection. See the link in the text version of this week's newscast at 
arnewsline.org

NEW HAM RADIO MUSEUM OPENS IN OHIO

STEPHEN/ANCHOR: Congratulations to Ohio's new amateur radio museum. It's 
the Waller-McMunn Museum in Cambridge that has opened to visitors in a 
restored radio station building after years of work by volunteers 
assembling the collection of ham radio gear and related items. The museum 
is the pride of the Cambridge Amateur Radio Association, W8VP. The name of 
the museum honors Homer McMunn who built the first radio receiver in 
Cambridge in 1912; it also pays tribute to his brother-in-law, Roy Waller 
who is credited with being the first to copy signals from a US Navy 
station operating in Arlington, Virginia that year. The two men were known 
as experimenters who built receivers and transmitters and operated a 
wireless station in town. Their enthusiasm eventually led to the creation 
of the Wireless Association of Cambridge.

RESEARCHERS CREATE THINNER, DENSER COMPUTER CHIPS

STEPHEN/ANCHOR: Researchers in the United States have created thinner, 
denser computer chips with big possibilities. We learn more from Kent 
Peterson, KC0DGY.

KENT: Denser and more powerful computer chips may soon be possible thanks 
to findings in a laboratory at the Massachusetts Institute of Technology. 
Researchers there have developed a means of working with 2D materials so 
slender that they are no more than three atoms thick. By layering them 
atop a fully fabricated silicon chip, they are able to create a denser 
integration.

According to the MIT news website, this low-temperature growth and 
fabrication technology does not result in damage to the chip. Damage was a 
major concern during previous attempts to achieve this integration atop a 
silicon CMOS wafer because the process customarily requires temperatures 
of 600 degrees Celsius. Temperatures above 400 degrees Celsius could cause 
the transisitors and circuits to break down. 

The news website also reported that this technology reduces the growth and 
integration process on an 8-inch wafer from more than a day to less than 
an hour. A shortened growth time is seen by researchers as particularly 
attractive for industrial fabrications because of its efficiency.

Researchers also said they want to explore use of this process for such 
flexible surfaces as textiles, polymers or papers, raising the prospect of 
integrating semiconductors into clothing, paper notebooks and other 
everyday items.

This is Kent Peterson, KC0DGY.
