These items are an archive of past Topical Smorgasbord items that have appeared on the RF Cafe homepage. In keeping with the "cafe"
genre, these tidbits of information are truly a smorgasbord of topics. They all pertain to topics that are related to the general engineering
and science theme of RF Cafe. Note: There is also a huge collection of my 'Factoids' (aka 'Kirt's Cogitations') that might interest you as well.

Friends, former employees, and fellow
lovers of all things electronic, we are gathered here today to remember and
honor our lifelong friend and enabler of our hobby and passion,
Radio Shack - once a Tandy company, as we are familiar with it. Radio
Shack has lingered in failing health for a decade, all the time keeping a
brave face on its dwindling number of stores. Caretakers attempted a variety
of infusions and transplants in an attempt to save the American stalwart electronics
retailer. Alas, a confluence of poor management ...
For Mother's Day this year, the kids and I
got Melanie a 23andMe DNA testing kit. She has spent a fair amount of time over
the years researching the family lineage which, in case you care, traces back primarily
to Germany and Switzerland. Along with some of the online ancestry websites, she
searched the U.S. Census database for immigration and early American household information
(number of people, ages, names, occupations, etc.) The entire
1930 Census form consisted of a single page seeking basic information on whether
you own or rent, value of the home, live on a farm or not, color or race, ...
Long-time RF Cafe visitor and occasional
contributor Gary Steinhour, KF6U, recently sent me a note saying he had acquired
a very used

now, and boy does it look nice! Gary provides a brief account here ...
If you have ever seen the result of a lightning
strike on electronic equipment, then you know how devastating it can be - often
total destruction that includes molten metal. Woe be unto any human operator who
happens to be in contact with it at the time of the strike. Unprotected antennas
are begging for contact. Shortly after leaving a company where I worked on a Tx/Rx
system for a phased array weather radar I got word that the indoor equipment rack
took a major hit because the guy who maintained the site forgot to reconnect a
rod system cable after moving it during ...
