The 470 ARG and the SCERS will be sponsoring a National Weather Service Skywarn Class in February on the 27th, of 2010, the location will be known by the next news letter, Tim Troutman will be the instructor for the class, we had looked at November but felt more time would be better and a Saturday could help more attend...
This weekend there is a Tech Class at the EOC / 911 Building at 245 Bruce Street starting at 10:00 am, those interested can call me at 865-429-2422, if not at home leave a message or e mail me at n4jtq@live.com ....
Lets get started ...

ARRL Board Adopts Guidelines and Recommendations on the Appropriate Use of Amateur Radio
On Friday, September 25, the ARRL Board of Directors adopted guidelines on the appropriate use of Amateur Radio on behalf of commercial, non-profit and government entities, as well as recommendations for additional steps to be taken by the ARRL to educate radio amateurs and others on how to prepare and train for public service and emergency communications while complying with the current FCC Rules.
At its meeting in July 2009, the ARRL Board created an ad-hoc committee to study the issue and prepare suggested guidelines. The committee submitted its report to the ARRL Executive Committee, which reviewed and revised the document. After additional discussion among Board members by electronic mail and teleconference, the Executive Committee submitted the document to the Board for formal adoption.
Entitled The Commercialization of Amateur Radio: The Rules, The Risks, The Issues, the document offers guidelines to assist radio amateurs and anyone wishing to utilize the capabilities of Amateur Radio in understanding the FCC Rules that prohibit communications in which the amateur has a pecuniary interest, including communications on behalf of an employer. While the FCC Rules in this regard have not changed in many years, there has been increasing discussion of the issue as growing numbers of employers and non-amateur organizations recognize the value of Amateur Radio as an emergency communications resource and encourage their employees to obtain amateur licenses. Also included are guidelines for evaluating the appropriateness of Amateur Radio volunteers providing communications services to commercial enterprises and other entities for which other communications systems are available.
"The guidelines are not intended to be the last word on the subject, and surely will not be," observed ARRL First Vice President Kay Craigie, N3KN, and chair of the ad-hoc committee. "The report includes several recommendations for additional steps that the ARRL needs to take to help amateurs and the organizations we serve to better understand the Rules and to ensure that what we do to prepare to be of service in emergencies is consistent with the current Rules."

Stepping into a time machine set on "just out of sight" is always an adventure. It's important that we have a sense of our technological history if for no other reason than to enjoy the fun as old becomes new again. This month, see if some of these references don't tickle some long-disused neurons, some from books and some from personal experience! Questions of inventors and discoverers may tread some grey areas of historical priority, but the answers reflect the most widely accepted reading.
1) What electrical function was performed by a "slop jar"?
a. Accumulate grid leaks
b. Rectify ac
c. Artificial ground
d. Transient clamping
2) Poulsen invented what device used in early transmitters?
a. Multiplier
b. Transformer
c. Arc
d. Tuner
3) What type of device was the "audion"?
a. Vacuum tube
b. Speaker
c. Headphones
d. Detector
4) To what was the nickname "Old Betsy" given?
a. Transmitter
b. Receiver
c. This was the term for "Murphy" before Murphy's Law was popularized.
d. QRN
5) Who is most widely credited with first describing vacuum-tube rectification?
a. Hertz
b. Maxwell
c. Armstrong
d. Fleming
6) Who invented the "single-signal" crystal filter?
a. Armstrong
b. Lamb
c. de Broglie
d. Marconi
7) A "TRF" is a type of what?
a. Antenna
b. Battery
c. Early coaxial connector family
d. Receiver
8) In a spark transmitter, what determined the strongest wavelength of the transmission?
a. Antenna system
b. Rotational speed
c. Gap spacing
d. All wavelengths were of equal strength
9) What was the original name for radio waves?
a. Cathode rays
b. Ethereal waves
c. Alpha particles
d. Hertz or Hertzian waves
10) Who discovered the electron and in what year?
a. J J Thomson (later, Lord Kelvin) in 1897
b. Dimitri Mendeleev in 1859
c. Ernest Rutherford in 1915
d. Albert Einstein in 1904
Bonus: What was the first solid-state device used in wireless communication?
Answers
1. b -- Consisting of strips of dissimilar metals in a caustic lye solution, you can see where the rectifier got its name.
2. c -- A Poulsen arc, also called an arc converter, converted dc into RF.
3. a -- A triode amplifier, manufactured by Lee DeForest.
4. a -- Old Betsy was Hiram Percy Maxim's rotary spark-gap transmitter, on display at W1AW.
5. c -- Fleming made use of the Edison Effect to create the first electronic device, the thermionic diode.
6. b -- Lamb applied the quartz crystal as a filter to limit receiver bandwidth.
7. d -- Tuned Radio Frequency receivers preceded the superheterodyne.
8. a -- The combination of the antenna's natural resonance and the coupling circuit from the spark gap acted formed a low-Q tuned circuit.
9. d -- For the physicist Hertz who conducted the first experiments with electromagnetic waves in 1887.
10. a -- Only four years later, Marconi spanned the Atlantic, 14 years before the discovery of the atomic nucleus!
Bonus: The Branly coherer consisted of an insulating tube filled with fine metallic particles -- usually iron filings -- squeezed between an electrode at each end. When a radio wave passed through the filings, their conductivity increased, allowing an external circuit to respond, creating a radio wave detector. Interestingly, vacuum tubes quickly replaced the coherer as a detector, delaying an understanding of the physics of its operation until 2005! The full story is told in the September 2009 issue of IEEE Communications Magazine by Jean-Marie Dilhac.
