-27 °F in Alpena, Michigan
°F (-31 °C) was the low temperature
in Alpena, Michigan this
morning, February 28, 2014. That was the official measurement at
the airport, which is typically a few degrees warmer than here on
Long Lake, about 15 miles north of there. I knew from the star-filled
sky last 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 and
frozen-solid, ice-covered ground. Our daytime highs and nighttime
lows have consistently been 15 to 20 degrees below...

author covers basics of satellite configuration, launching, and

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
Electronics and the IGY - Part I
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). The Cold War was at its peak

science world was looking for a way to provide a unifying tie between

Modern Radio Practice
in Using Graphs and
memorizing multiplication tables, the proper spelling of words,
the location of countries on a map, et cetera, is being questioned
by many people these days (mostly low-achieving
dummkopfs) based on an easy access to data on the Internet
and other media. All such people need to do is get fairly close
to spelling topics of interest correctly 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 to basic life skills of course, not nuclear science
or phenology. The obvious advantage gained in memorization is developing
an intuitive feel for what the entire realm of subject entails.

Whole House Humidifier
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
mitigate low humidity conditions is to add water back into the
air. One way is to use a free-standing humidifier that either evaporates
water back into the air or to use an ultrasonic...

RF Cafe Quiz Microwave
and mm-Wave Packaging
quiz is based on the information presented in
Microwave and 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. Note: Some of these books are
available as prizes in the monthly

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

How to Interpret Standard
Ratings for Meter
with the ubiquitous (and inexpensive)
presence of digital multimeters, there are still times when a meter
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 with a digital meter can be very misleading...

design concepts that will make your products eye-catching and appealing,
and shows you ways to scale up from a single prototype to mass production.
as early cellphones (Motorola's Bag Phone,

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

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
