Active Sunspot Space Weather News for June 12, 2010 http://spaceweather.com ACTIVE SUNSPOT: A new sunspot has popped up and it is crackling with solar flares. Today, AR1081 has unleashed a series of M- and C-class eruptions plus at least one strong shortwave radio burst detected by amateur radio astronomers on the Pacific side of Earth. High resolution movies of the flares and an audio recording of the solar radio burst may be found at http://spaceweather.com. New Comet in the Morning Sky Space Weather News for June 8, 2010 http://spaceweather.com NEW COMET McNAUGHT: A fresh comet is swinging through the inner solar system, and it is brightening rapidly as it approaches Earth for a 100 million mile close encounter in mid-June. Comet McNaught (C/2009 R1) has a vivid green head and a long wispy tail that look great through small telescopes. By the end of the month it could be visible to the naked eye perhaps as bright as the stars of the Big Dipper. Because this is the comet's first visit to the inner solar system, predictions of future brightness are necessarily uncertain; amateur astronomers should be alert for the unexpected. Visit http://spaceweather.com for sky maps, photos and more information. _______________________________________ Digital-ATV ________________________________________________ ^ Overview of DVB-T Modulation Hi Bryon N6IFU, This month I wrote a new DATV article for our local Orange County ARC newsletter. This month’s article.... ^ takes a look at DVB-T, the second most popular modulation protocol for ham Digital-ATV. The article describes the capabilities of the three modulation schemes that can be selected for DVB-T...QPSK, QAM-16, and QAM-64.....and also describes the Power-Amplifier de-rating that is needed. Near the end of the article is a table of PROs and CONs comparing DVB-T with DVB-S and also with ATSC protocols. This DATV article can be found at the OCARC WEB site at www.W6ZE.org/DATV/ I thought you and your readers might be interested to learn a little more about DVB-T. 73...de Ken W6HHC OCARC ************************************************************ Send me your D-ATV News.. atv-newsletter@hotmail.com _______________________________________________ ^ ________________________________________________ By Mario, KD6ILO

News ___________________________________________ ^ Over the weekend I heard Dave, KA6DPS talking with another ATVer about the 3 GHz output on Oat Mtn.. Dave said that he heard that all the equipment needed to add the 3 gig output to Oat was in hand but he didn't know what the hold up is. So it sounds like the 3 GHz output could be installed anyday. ___________________________________________ ^ Got a joke? send it to atv-newsletter@hotmail.com _______________________________________ _______________________________________ ^ __________________________________ ______________________________________ Repairs Needed for the ATN-CA Repeaters ________________________________________ Blueridge: 1. Establish link from Mt. Potosi Mt Wilson: Saw testing on 3/21/10.on 434 MHz and it was working Oat Mtn.: 1. Replace plastic wire ties with appropriate fasteners. 2. Tune 2.4 GHz link dipole for better SWR. It would be a good idea to sweep the 1200 MHz antenna at the same time as well. 3. 3 GHz output could be installed anyday 6/15/10. Santiago Peak: 1. Remove KC6UQH's call and Palomar from the W6ATN repeaters ID's (late spring early summer 08 when the new controller is installed) (Removable requested buy the Palomar Amateur Radio Club and KC6UQH in 2007) 2. Look into weak signal getting into one of the inputs. 3. Find intermittent receive problem for link from Oat Mtn..(1/24/09) 4. Resolve problems with WiFi getting into receiver for Snow Peak & Point Loma (April 28, 2009) Snow Peak: 1. 2.4 Ghz input is operational but has audio problems due to receiver problems on the network hub.. July 23, 2009 2. The 1200 MHz output does work and you can watch. 3. Get repeater back on the air. Point Loma, W6RDF: No Repairs Needed/Fully Operational Trustee Robert Swain, KA4JSR 1. Off the air do to AC problems at the shack. 2. 434 input unuseable (4/03.01) ______________________________________ _______________________________________________ _____________________________________ Letters to the Editor ************************************************************ ^ If you would like to send a "Letter to the Editor" and want to have your name withheld to protect your identity so as to shield yourself from the attacks I will print your letter, but I must know who you are and be able to contact you.
