Kevin, I first worked Al in May 1978 on RS-12. He was my 85th contact and I believe he was just starting out as well. Neither of us had good V/UHF rigs at the time, so HF satellite was the way to go. Seems like yesterday... 73, Jerry, K5OE > How long did that take might I ask? I have noticed my log is growing, and I > mostly operate on weekends. Anyway just curious... > > Kevin > KF7MYK

Al is my hero. I noted from the March QST he is also among the top ops in 2m EME. 73, Jerry, K5OE

AO-51 mode change 16 March 2120utc
by Mark L. Hammond 16 Mar '11

16 Mar '11

Hi All, The power budget on AO-51 has really been stretched with both transmitters on, so we are now in single transmitter mode. That means quite a bit more power on 435.300 (the voice repeater), which is now around 1.3W or so. We'll be in this mode for a while (until further notice). You'll probably still hear the transmitter cycling OFF and ON around eclipse times. But most voice users will appreciate the stronger signals. 73, Mark L. Hammond [N8MH]

Solar Power for Portable and Home
by Bob Bruninga 16 Mar '11

16 Mar '11

New Solar Power DIY group formed. Could not find a Solar Power group similar to the expertise and experience of hams that are also into solar. So I formed a new one. SolarDIY(a)YahooGroups.com Existing groups were too narrowly focused, or too broadly focused including pperpetual motion generators and other whacky ideas. I learned a lot in powering my SHACK and portable satellite operations from solar. I'd like to learn more from others. Basically the kind of group like hams but with an interest in alternative and backup energy. Bob, WB4APR

Using Preamps In Shack
by Paul Delaney - K6HR 16 Mar '11

16 Mar '11

Does anyone have their preamps in the shack as opposed to mast mount? Any major disadvantage to having the preamps in the shack? I just acquired two AR2 SPxxxVDG preamps and understand they are not weatherproof and would need an enclosure to mount near antennas, which for the time being is not possible. Any thoughts would be appreciated. Paul Delaney - K6HR paul.hamradio(a)verizon.net http://k6hr.dyndns.org:8080

AO-51 - Idaho Repeater QRM on uplink?
by David Palmer 16 Mar '11

16 Mar '11

Hi Everyone, I just thought I'd relay a bit of QRM I observed on AO-51 on this morning's 3/16/2011 1322z pass. The bird was totally quiet (just a nice carrier) for the first 5 minutes of the pass, but then it sounded like a repeater was getting into the sat uplink: 3/16 1327z: "Connected, KD7QAF repeater." 3/16 1328z: "KD7QAF repeater disconnected." 3/16 1328z: "hey Stacy did I see you at the corner there by Wendys?" 3/16 1330z: "...repeater in Middleton, Idaho." Pretty minor as far as QRM goes, but I just wanted to flag it up in case anyone knows of a KD7QAF repeater (call might have been KD7QAN?) that's got an output near 145.920. Might be worth letting them know they're getting into a sat. Also had a nice chat with Kerry WC7V on the same pass -- I'd forgotten how nice it is to work AO-51 on the early morning passes, it's a fantastic satellite!!! The morning passes aren't crowded at all, and '51 has such beautiful clear audio and great coverage. 73 de Dave KB5WIA / CM88

The natural circulation is west to east so possible that some radiation could transverse the world. During the Chernobyl accident radiation was detected in Alaska. Probably into western US, also. Chernobyl impacted eastern Europe and Asia more, but was located in the Ukraine. Japan is much closer to the US. At this point the radiation release is much less than what happened in Chernobyl. It is more a danger in the immediate area surrounding the plants. If the reactor container has a breach then one can only guess the results. So far it has been intentional release of radioactive steam resulting from heat of the reactor core and fuel rod storage area. Unfortunately H2 gas is released in the extreme heat as sea water was applied for cooling and that led to explosions. 73, Ed - KL7UW, WD2XSH/45 ====================================== BP40IQ 500 KHz - 10-GHz www.kl7uw.com EME: 144-1.4kw, 432-100w, 1296-testing*, 3400-winter?
