separating the phased array into two more manageable pieces

Repair and Restoration of Antique Radio Equipment, ppt slide show

This past Wednesday i was the speaker at the MIT Haystack Observatory
open lunch meeting where I presented a briefing on repairing and
restoring antique radio equipment, using my Hallicrafters S-76 and
Colin B. Kennedy Model 20B console radios as case studies.

The briefings are available to anyone who is interested, here they
are in pdf, key, and ppt formats:

i'm making changes to a journal, trying to shave one more page off of it

It is tough to shrink your article, and once you are down to one page
it is the most difficult. Every word counts...

Ford's first car

Had the opportunity to see Henry Ford's first car this week.
Amazing! If you look closely you can see where mistakes were made,
extra hole drilled here or started there. The frame is made if angle
iron and everything is bolded together. A true prototype! And, very

IEEE Phased Array 2010

Thanks to the explosion of low-cost wireless components there will be
many more phased arrays spanning numerous applications in the near
future; consumer, scientific observation, and military. For this
reason it is important to learn about the latest trends and
developments in phased array technology.

Good news: The 2010 IEEE International Symposium on Phased Array
Systems & Technology is coming up soon, October 12-15 of 2010.
Abstracts are due December 1st (2009). Consider submitting a paper
on your phased array project or at least attending this conference to
learn about the latest advances in phased array systems:

making corrections to IEEE APS paper

I am extremely pleased with the feedback from APS on a paper that i
submitted this past spring.

This paper describes a S-band UWB rail SAR imaging radar system that
i developed using a discarded Genie garage door opener, some crystal
filters from a communications receiver, a bunch of surplus parts
combined with a Labview NI card. The results were surprisingly good,
especially considering the low-budget available to develop this system. See web article:

If you find this sort of UWB S-band rail SAR stuff interesting then
stay tuned to IEEE APS Transactions.
