UPDATE: AMSAT ARISSAT-1 Rockets Into Space
From the WorldRadio Online Newsroom. . .
The ARRL reports that a Soyuz-U rocket carrying the AMSAT ARISSAT-1 satellite lifted off from the Baikonur Space Center in Kazakhstan January 27, heading for the International Space Station. The Progress M-09M cargo vehicle is also carrying fuel, oxygen, food and other supplies for the space station. It is scheduled to dock with the station on January 30 at 0240 UTC.
ARISSAT-1 is scheduled to be hand-launched during a spacewalk on February 16. It features a new software-defined transponder that will allow simultaneous FM, CW and BPSK transmissions on 2 meters, along with a traditional Mode U/V transponder (70 centimeters up, 2 meters down). The satellite has no propulsion system and will circle the Earth until its orbit decays and it burns up on re-entry to Earth's atmosphere.Click here for more information at the AMSAT-NA website.

For Radio Amateur Photographers - Who Find They Have a Screw Loose
(As more and more radio amateurs share their operating, equipment and antenna experiences with fellow hams through digital photography, WorldRadio Online columnist Bill Pasternak, WA6ITF, offers some real-life advice on a little-known remedy some camera lock-up problems - Ed.)
By Bill Pasternak, WA6ITF
A few weeks ago, I pulled out my trusty Canon A530 Powershot digital camera to grab a few photos of my grandkids.
I got off one shot and the camera failed. Its flash circuitry failed, putting the camera into perpetual recharge the flash mode while locking out all other functions. If I turned the camera off, I could take another photo but then it would lock-up again.
To make a long story short, I visited the Canon USA website but could find no help there. I spoke or e-mailed with several companies that repair digital cameras and in each case was told it would likely be to costly to repair. Likely over $100 for a camera that had cost me only $135 some five years ago.
Still, it was a camera I really liked because it had a “Real Image” zoom viewfinder in addition to the LCD screen. After a lifetime of shooting with 35mm SLRs and range finder cameras, I’ve never been happy composing a photo on the LCD.
That said, I was becoming resigned to having to buy a replacement. To my surprise nothing on the market had the traditional eye level finder I desired, so it was back to the Internet to find a fix for the A-530.
An exhaustive Web search led me to Do It Yourself Digital Camera Repair. It had the answer to the Canon fix - with nothing more than a small Phillips head jewelers screwdriver.
Scrolling down the page I came to an article titled “Simple Fixes for Cameras that Won't Take a Picture When the Shutter Button is Pressed” The first two paragraphs described my problem and presented a possible fix. I quote:
"Everything seems fine with your camera, except that when you press the shutter button nothing happens! On Canon cameras you may also notice flashing yellow/orange lights by your viewfinder. Try switching to any mode other than automatic, turn off the flash, and press the shutter button. Did the camera take a picture? If so, continue reading."
That was exactly my problem, so I continued:
"Many cameras have a safety feature that prevents the flash capacitor from charging if the case is opened. This is to lessen the chance of electric shock. They usually use one or two of the screws along the perimeter of the camera to complete a circuit that lets the processor know that the case is closed. Verify that all the screws are in place along the perimeter of your camera, and that there are no gaps along the perimeter seams. If you're missing a screw, try using one of the others to replace it."
Well, I was not missing any of the case screws and none seemed loose, but I decided to try loosening and re-tightening the five visible screws holding the A530 case halves together. I grabbed the needed tool out of the desk drawer, performed the task and then turned on the camera. I shot a random photo and then waited to see if the yellow flash charge indicator would remain in perpetual blink mode. A few seconds later it went green indicating the camera was ready for its next shot. Problem solved.
So there you have it. A screw not making electrical contact or perhaps not hitting a tiny microswitch? Who knows. I’m not going to pull the camera apart to find out. It’s working and that’s all that counts.
The bottom line: My A530 is alive and well again. Do It Yourself Digital Camera Repair has a wealth of information that can save your digital camera from the junk heap while giving you insight into what makes your digital camera click.

FCC Releases NPRM on Employer Communications
March 24, 2010
The FCC has issued a Notice of Proposed Rule Making (NPRM) addressing the question of whether hams should be able to communicate on behalf of their employers in certain limited circumstances. The NPRM proposes adding a narrow exception to the general prohibition on communications on behalf of an employer for amateurs involved in government-sponsored emergency drills. It also seeks comments on whether certain other drills that are not sponsored by government agencies - such as those conducted by hospitals - should be included in the proposed exemption as well.
The proposed new language for Section 97.113(a) of the FCC rules would read as follows:
(i) A control station operator may participate on behalf of an
employer in a government-sponsored emergency preparedness or disaster readiness test or drill, limited to the duration and scope of such test or drill, and operational testing immediately prior to such test or drill.
Click here to see the complete text of the NPRM on the FCC website.

Comments may be filed online via the FCC's Electronic Comment Filing System (ECFS). Reference WT-Docket 10-72. Comments are due 30 days after the NPRM is published in the Federal Register (which usually takes about a week after release).
