RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling
2 MB. Its primary purpose was to provide me with ready access to commonly needed
formulas and reference material while performing my work as an RF system and circuit
design engineer. The World Wide Web (Internet) was largely an unknown entity at
the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps
while tying up your telephone line, and a nice lady's voice announced "You've Got
Mail" when a new message arrived...

Nuclear Fission Event Reported in Earth Orbit (source:
Space.com) |
 A news report on February 11, 2009, told
of a "very low-probability" impact between an expired Russian Cosmos satellite and one of the operational Iridium satellites. Both were
traveling more than 16 kmph at an altitude of 491 miles. Total destruction ensued, with two clouds of debris to be added to the ESA's
animation. The Iridium System originally was to consist
of a constellation of 77 satellites - think Bohr atomic model of the 77th element in the
periodic table. Budget cuts forced a reduction to just
66 satellites - the Dysprosium System. We now have the Terbium System (65). Can you hear me now? |

Conspiracy Uncovered (source: Sky & Telescope)
|
  Is there a common theme with these two images? Maybe that both are religious symbols seen all throughout the
land? One is a church building, and the other is... a power distribution pole. I smell an ACLU lawsuit here demanding the removal of such blatant
religious symbols as are these poles - at least those on public land. Separation of Church and State requires as much (is that really in the
Constitution?). The
source of the images? Sky & Telescope magazine; it is part of their monthly all-sky star chart. Those fanatics at S&T must be sending
a subliminal message.Remember, you heard it here first! |

"...We've switched from a tabloid format... It fits easily into a briefcase... or even folded into a jacket pocket. This is what we're telling
everybody, anyway. When we deliver this schpeil[sic] to friends at trade shows and other gatherings, they listen patiently and politely. Then
comes ... 'Yeah, yeah, that's all nice; what's the REAL reason you're changing the book from a tabloid to standard magazine?' Here's the honest
answer: We're keeping our print magazine relevant in the Internet age. Some folks say print is dead. We say print is as important as it
ever was–except that it has to reinvent itself to live happily and productively beside that 500-pound gorilla we know as the Internet." -
John Keller Print might not be dead, but it is on life support. |

U.S. Trade Balance in High-Tech Goods 2000-2004 (source:

If you think that the U.S. has gotten into the bad habit of importing more high tech products than it exports... then you are correct.
It is not difficult to extrapolate to the next few points through 2007, but seeing the 2008 and 2009 data will be very interesting. |
