night that it was going to be frigid. Without a cloud cover to insulate the Earth, radiative
cooling can be quite pronounced, especially in low humidity conditions as found in the desert

International Geophysical Year (IGY) articles that appeared
in Radio-Electronics magazine. The author covers basics of satellite configuration,
launching, and tracking based on knowledge of the era. Keep in mind, though, that the U.S.
had not actually launched its first satellite at the time. In fact, the two satellite models
shown possess antennas suggesting active radio circuits within, but Echo, our first earth-orbiting
satellite, was just a metallized plastic sphere that passively reflected radio signals. The
Russian Sputnik, by comparison, did have electronic circuitry onboard.
International Geophysical Year (IGY) began on July 1 of 1957
and ran through December 31 of 1958 (actually IGYaaH - IG year-and-a-half).
It was the dawn of space / high altitude flight and there was a great need to learn as much
as possible about the physics of the upper atmosphere and the void of space. The USSR successfully
flew their first three Sputnik satellites and the U.S. was scrambling to get Echo into orbit
(finally on August 12, 1960, after the end of IGY).

memorizing multiplication tables, the proper spelling of words, the location of countries

low-achieving dummkopfs) based on an easy access to data on the Internet and other

and other people who do not subscribe to the aforementioned philosophy have seen to it that
the laziness and ignorance of those who do subscribe are duly accommodated. I'm referring

large portion of the U.S. has experienced prolonged periods this winter with temperatures
substantially below long-term averages. That means heating systems have been running much
more often than usual, and if you have a forced hot air system, that means the indoor humidity
level has been much lower than normal. In northern areas like where I live, humidity can easily
drop to near zero. Because of that, triboelectric charging to high voltage potential occurs
merely by walking a few steps across a carpet, resulting in a sometimes painful discharge
arc when a metal object is touched. The only way to
low humidity conditions is to add water back into the air. One way is to use a free-standing

Scott Transformer Company advertisement that appeared in a 1930 edition of Radio News.
I'm not sure how many radios Scott sold, but a fairly extensive Google and eBay searches turned
up only one restored model of the fancy "artistic" cabinet type. Based on the prices in the

Millimeter-Wave Electronic Packaging, by Rick Sturdivant. Packaging of electronic components
at microwave and millimeter-wave frequencies requires the same level of engineering effort
for lower frequency electronics plus a set of additional activities which are unique due to
the higher frequency of operation. Without careful attention to these additional issues, it
is not possible to successfully engineer electronic packaging at these frequencies.

my electronics technician days at the Westinghouse Electric Company's Oceanic Division in
Annapolis, MD, I spent the first couple years building printed circuit boards, wiring harnesses,
and system-level assemblies for U.S. Navy sonar systems. We had some really slick stuff like
towed vehicles with transducer arrays along the sides, nose cones for smart torpedoes, flow
sensors, proximity fuse
etc. Exposure to all that, and the super-smart people that designed it, fuelled my desire
to go to the trouble of earning an engineering degree. One of my tasks for a while was to
build the transducer arrays, which entailed building the hundreds of tiny transducer elements.
One of the phased array acoustic antennas was mounted on each side of the

there are still times when a meter sporting an
analog movement is more useful than a numerical display. This is especially true is when
a reading is varying about a mean value rather than being fixed. Sampling and display update
times of digital meters can be too slow to realistically reflect what a time-varying signal
is doing. An analog meter's pointer can more readily be followed than needing to read and
mentally comprehend a rapidly changing numerical value. Digital meters are great for reading
a fixed value or for precisely setting a fixed value, but tracing signals through a circuit

is as prevalent today as is was at the beginning of radio communications - maybe more so since
there are typically more reflective obstacles between the transmitter and the receiver. The
evidence of multipath with digital communications, be it voice, Internet page viewing, or
movies, is slowness in transmission as opposed to the analog case where garbled speech on
radio and ghosting pictures on television are the evidence. High data rates with digital transmissions
typically mask the packet errors and their necessary re-transmission; it all happens before
the buffered information is presented to the listener / viewer. However...
