In this tutorial, I will show how to create a basic story on the website with no pictures, tables, lists, code listings, or other HTML. With the information in this tutorial, you should be able to post a simple quick and dirty story on the club website, such as 90% of the stories published in the first 2-1/2 years of this website being hosted using drupal but not a fancier page such as this tutorial page or some of my recent postings. You might have been hoping I would show you how to do those right away, but you need to walk before you can run.
The Albemarle Amateur Radio Club will meet in the National Radio Astronomy Observatory, 520 Edgemont Road, Charlottesville, VA on July 9 at 7:30 pm. Charles Battig K4TY will give a presentation on Smart Meters (home electric service meters) and RFI.
The president has called a board meeting for 7 pm. prior to the 7:30 General Membership Meeting.

This is just starting to percolate into the news. The FCC last friday approved release of google's TV white spaces database which documents what unused TV channels may be used for wireless internet access type services in which areas. You can browse a visual representation in google maps:
On this page, you can download these databases that include US, Canadian, and Mexican TV Sations, TV translators, Broadcast Auxillary SErvice Links, PLMRS/CMRS base station operations, Multi-channel Video Programming Distrbutor (MVPD) receive sits, Temporary BAS links, Low Power Auxillary Devices, Fixed TV-band white space devices.
These databases might be more accurate than the usual FCC transmitter and tower databases for parts of the spectrum since if you aren't in this database someone is likely to start transmitting on top of you.
Another reminder that unused spectrum is up for grabs.
As some already know, the 146.730 repeater is usually connected via IRLP to the East Coast Reflector (9050). To see the current nodes connected to 9050 go to:
The 73 repeater uses a simplex UHF frequency on the 2nd port of the repeater controller to communicate with another UHF radio at the 4703 node located at Zehmer Hall on UVA grounds. As the 9050 reflector usually has around 30 different nodes connected, when you key up the 73 repeater, your audio has to pass to the UHF radio, transmit to the UHF radio at the node, pass by VoIP to the reflector, located in Michigan, travel by VoIP to the other node computers, and then by whatever connecting hardware is used to pass the audio to the repeater connected to that node. This means that with each transmission, there is a lot of hardware distributed from Michigan to Florida, that needs to be lifted up from its idle state. What does this mean for you the user? All you need to remember is to key your mic and wait a second or two before you start speaking. Also, it is important when the other station stops speaking, wait a couple of seconds before you key up your mic. Also, be aware that there are no repeater controller ID's or courtesy tones that go out on IRLP. There is a short courtesy beep that the link UHF radio gives back on the 146.730 repeater, but the other station needs to know that you are turning over the conversation by ending your transmission with "over" or "back to you".
Does this mean that the 73 repeater shouldn't be used for local conversations? No, local conversations are fine, but the general rules of pauses still need to be applied, because when you are talking locally, your local conversation is going out to the entire reflector population. If you are planning on an extended conversation locally, just DTMF the code 73 and that will drop the 146.730 repeater from the reflector. When your local extended conversation is completed, DTMF 9050 to reconnect to the reflector. Likewise, if you would like to connect to another reflector, or individual node, disconnect from the 9050 reflector, and send the DTMF code for the other reflector, or node. Connections to reflectors will not timeout, they have to be broken by sending 73. On the other hand, connections to individual nodes will timeout in 4 minutes of inactivity.

I have scanned and uploaded 13 years of past newsletters, 1992-2004. The newsletters are an important part of the documentation of the clubs history. They include:
As many of you know, back during the changing of the guard from last years leadership to this years, I encountered 4 binders worth of back issues of the beacon and although back issues of the beacon are online back to 2005, the contents of several of these binders were not found on the website. I realized that these might be the only copies or one of a few copies remaining of these important documents. If they were lost or destroyed, the info might be gone forever. And their use is limited sitting in the secretary's house where they are not as readily available. Taking leave of my senses, I undertook the task of scanning these beacons. And thus began a tale of fighting with bad drivers, slow software, and misfeeds caused by pages which had been folded, spindled, and mutilated.

“Who ya’ gonna call? Charlottesville/Albemarle area Radio Hams!”
Charlottesville, VA 2013-06-17 – Despite the Internet, cell phones, email and modern communications, every year whole regions find themselves in the dark. Tornadoes, fires, storms, ice and even the occasional cutting of fiber optic cables leave people without the means to communicate. In these cases, the one consistent service that has never failed has been Amateur Radio. These radio operators, often called “hams” provide backup communications for everything from the American Red Cross to FEMA and even for the International Space Station. Your Town’s “hams” will join with thousands of other Amateur Radio operators showing their emergency capabilities this weekend.
The general public is invited to attend Field Day. The AARC will again be operating Field Day from the Earlysville Volunteer Fire Department at 283 Reas Ford Rd, Earlysville, VA. We will begin our on the air operations at 2:00 PM Saturday June 22, and will be on the air continuously until 2:00 PM Sunday, June 23.
The Amateur Radio License Test (VE Session) will be 9:00a on Saturday at the Earlysville Fire Dept.

Would you like to participate in a first of its kind, Foxhunt in Space? The Foxes are miniature spacecraft, dubbed “Sprites” that will be launched into low earth orbit in mid-November 2013 for a limited engagement. Want to find them? . . . .With a few fairly inexpensive parts and rudimentary assembly skills, interested members of AARC can take part in a pioneering experiment in space. Does this grab your attention? If so, read on.
Zac Manchester (KD2BHC) an Aerospace Engineering Graduate Student at Cornell, and his group, chaired by his mentor, Mason Peck, PhD, are preparing to launch several small "KickSat" satellites later this year, piggybacked aboard a SpaceX craft, the prime mission of which is to replenish the International Space Station (see CQ April 2013, pp 74-5). Each KickSat will deploy about 100 solar powered "Sprite Satellites" into low Earth orbit During a recent telephone conversation I had with Zac, he asked us (AARC) to consider joining a growing number of Clubs and Academic Departments who will monitor RF signals transmitted by the satellites.
DETAILS: Each Sprite is a circuit board about the size of two postage stamps, with a mass of 5 grams (that of a U.S. nickel). The board is populated with solar cells, a gyroscope, a magnetometer, a UHF radio transmitter, a micro-controller, a dipole antenna and other components. Individual Sprites will transmit a unique series of characters, usually a few letters, "Like your initials," according to Zac. Currently, three Sprite prototypes are orbiting earth in a Materials Science Experiment Pallet that was mounted on the outside of the ISS in 2011 during the final mission of the Space Shuttle.
As of last monday, there is a digital net on the 146.730 repeater on monday nights at 8:15PM local time, shortly after the info net (which is voice and on a separate frequency). Probably using MT63-2000 modulation which works well over FM and at least passably with accoustic coupling between computer and radio (no interface needed), although a interface such as a signalink USB would be better. A number of software packages support this, including fldigi (Linux, Free-BSD, OS X, Windows XP, NT, W2K, Vista and Win7). There are also MT63 apps for android and iphone. Include the supplemental programs which are sometimes packaged separately from fldigi as some of these are used to support Narrow Band Emergency Messaging System (. NBEMS) transmission of emergency message forms.
