The Green Bank Telescope

UPDATE – Currently closed to the public.

Scientists come from around the world to use the Green Bank Telescope, because it is the most accurate, versatile, large dish radio telescope in the world. Its suite of receivers covers 100 MHz to 100 GHz in frequencies, its processors can spot nanosecond timing differences in data, and it observes under radio-quiet skies. The Green Bank Telescope can be used to do chemistry, physics, radar receiving, and astronomy and has no equal in the world.

With spring and summer around the corner it would be a good time to visit Greenbank and nearby is Cass Railroad. The Snowshoe resort offers very reasonable rates in the summer after the skiing season plus there are motels and B & B’s in the area. Greenbank is an easy and scenic drive from Pittsburgh approximately 4 hours.

AREDN

Amateur Radio Emergency Data Network

AREDN (Amateur Radio Emergency Data Network) was an outgrowth of the ARRL working group on High-Speed Multimedia (HSMM). It has evolved over the past 10-12 years from its first implementation by Broadband Hamnet (BBHN). Over the years the AREDN Project has developed software support for nearly 70 commercial wireless routers—moving them from their Part 15 allocation into adjacent Part 97 allocations in the .9, 2, 3, and 5 GHz bands—providing an inexpensive and easy way for hams to implement high-speed (up to 144 Mbps) data networks in support of Emergency Operations Centers (EOCs), Non-governmental Agencies (NGOs) and first responders. The project has twice been recognized by the league for the significance of its achievements by awarding the Project the ARRL Microwave Development Award in 2014 and 2018.

With are hilltop location this could be a viable system for emergency communications if the internet went down. There are 2 hams in the area now using it in the North Hills but other parts of the country have some very extensive systems in place. AREDN can also be used for controlling off site repeaters and remote stations with out relying on the internet. For more info checkout…www.arednmesh.org/

The primary goal of the AREDN® project is to empower licensed amateur radio operators to quickly and easily deploy high-speed data networks when and where they might be needed, as a service both to the hobby and the community. This is especially important in cases when traditional “utility” services (electricity, phone lines, or Internet services) become unavailable. In those cases an off-grid amateur radio emergency data network may be a lifeline for communities impacted by a local disaster.

Costs of devices range from $50 to several hundred dollars for a complete node, so there are many options even for the budget-conscious operator.

It would be nice for are club to implement this in the Pittsburgh area.

WSM “THE LEGEND” 650 AM

I am going to try to recognize a famous radio station every month this year in celebration of KDKA 100th anniversary. WSM signed on October 5th 1925 The Opry began as the WSM Barn Dance on November 28, 1925. In 1932, WSM boosted its power to 50,000 watts becoming Tennessee’s first clear-channel station. WSM’s unusual diamond-shaped antenna (manufactured by Blaw-Knox) is visible from Interstate 65 just south of Nashville (in Brentwood) and is one of the area’s landmarks. When the 878-foot tower was built in 1932, it was the tallest antenna in North America. Its height was reduced to 808 feet (246 m) in 1939 when it was discovered that the taller tower was causing self-cancellation in the “fringe” areas of reception of the station (it is now known that 195 electrical degrees, about 810 feet, is the optimum height for a Class A station on that frequency). For a period during World War II it was designated to provide transmissions to submarines in the event that ship-to-shore communications were lost. It is now one of the oldest operating broadcast towers in the United States.

The call letters “WSM” reflected National Life’s motto: “We Shield Millions.”

Winter 2020 Classic Exchange

Winter 2020 Classic Exchange (CX) Rules
CW Sunday Jan 12 1400Z to Jan 13 0800Z Tuesday Jan 14 1400Z to Jan 15 0800Z
Phone Sunday Feb 9 1400Z to Feb 10 0800Z Tuesday Feb 11 1400Z to Feb 12 0800Z
Bands 160-80-40-20-15-10-6-2
Modes CW, AM, SSB
Power Keep it legal…..
The CX is a no-pressure contest celebrating the older commercial and Home Brew equipment that was the pride and joy of ham shacks many decades ago. The object is to encourage restoration, operation and enjoyment of this older Classic equipment.
You need not operate a Classic rig to participate in the CX. You may use any rig in the contest although new gear is a distinct scoring disadvantage as your multipliers are directly related to the age of the equipment you use! However, you can still work the “great ones” with modern equipment.
There are two (2) entry categories per mode: ►Three or fewer receiver-transmitter pairs ►Four or more receiver-transmitter pairs.
Each CX event has bonus points. Details in the Bonus section!
There will be CX recognition for high scores in AM, SSB, and CW as well as overall.

RemoteHams now on TS-2000

The TS-2000 remote station is now on RemoteHams but still can be operated using TightVnc. With RemoteHams there is no need to use Skype for the audio link and RemoteHams can be downloaded on your Android phone or tablet. The service is free for computer use but there is a one time fee of $10.00 for the phone App. There will be a demo at the club in the beginning of January 2020 but in the mean time you can download RemoteHams Client on your computer to give it a try. We have to install a new hard drive in the TS-2000 computer between the holidays but the Greene County remote is still running under WA3VXJ call sign. Once you get the Client software running and search W3KWH or WA3VXJ and ask permission to use remote comes on your screen we will go into the software and give you permission. No need to take your laptop with you on a trip because the cell phone APP works great.

 

Today in History: December 12

1901: First radio transmission is sent across the Atlantic
Italian physicist Guglielmo Marconi (L) and his assistant, George Kemp received a message sent from Poldhu, England, at Signal Hill, St. John’s, Canada. The transmission message was the Morse code signal for the letter “s.”
