A pleasant surprise at the International Microwave Symposium (IMS) 2009 (also see IMS2011) show in Boston was the "Historical Booth." It had a very nice display of items from the early days of radio and radar. According to the IMS 2009 website, the items are "memorabilia from the first IMS held in Boston 50 years ago." Most displays were glass cases, so it made getting useful photographs difficult because of glare and reflections. You will see some of that in the images here. More information can be found on the National Electronics Museum website. Barney Fife, seen in the first photo, was dutifully guarding the displays. After seeing what was included, I was glad that the show organizers decided to place him there.
In retrospect, I should have taken many more photographs of the displays and suffered through attempting to remove the glare and reflections, because a lot (maybe all) of this stuff cannot be found documented anywhere on the Internet. One item in particular I wish I had photographed was what appeared to be a specially formed section of waveguide (maybe C-Band based on size) that had been routed out of a block of wood, and then the cavity was lined with copper foil.
We've come a long way, baby!
In order to keep page loading time reasonable, I have reduced most of the images to fit on half the page. Clicking on an image will display the full-size version. Some image files are very large, but I wanted to try to retain enough resolution to be able to read the text in the images. Please contact me if you would like to use any of the images in your publication. If you use them without permission, please at least credit RFCafe.com.
Please take a few more minutes to read my report on the rest of the IMS 2009 show, "RF Cafe Goes to Beantown."
Large display of patents, photos, manuals, and an example of the VT-158 tube.
