[amsat-bb] ARISSat-1 voice messages
All audio files of the message by children of all the countries of the world sent to by ARISSat-1 and the translated sentence were uploaded in SatBlog of the DK3WN station. I can guess that it would be hard to collect these messages. This is a laborious work. Please hear all once. A password appears in the last of the message of each country, but already I thinks this to be statute of limitations. http://www.dk3wn.info/p/?p=25476 JE9PEL, Mineo Wakita ___ Sent via AMSAT-BB@amsat.org.

RADIATION STORM IN PROGRESS: Solar protons accelerated by this morning's M9-class solar flare are streaming past Earth. On the NOAA scale of radiation storms, this one ranks S3, which means it could, e.g., cause isolated reboots of computers onboard Earth-orbiting satellites and interfere with polar radio communications.

[amsat-bb] Re: spaceweather.com
Commercial AM radio was acting strange this morning. A station that I only receive at night time (DX) was covering a daytime station that I don't usually have an issue with. That was backwards to what I thought would happen during a solar event.

[amsat-bb] Re: Quadrifilar Helix antenna question
QFH are a bear to build, especially on 70 cm unless you’re very , very skilled. I tried 3 times and failed 3 times. Finally gave up and went with a standard turnstyle. Still critical tolerances but much easier to make and works lower on the horizon than the QFH. QHtenna used to sell turnstiles (reviewed in QST) but I think they are out of business now. You might also want to consider a moxon. Cebik wrote a nice article on making a moxon based turnstile. I built one for 70 cm using PVC and like the QFH and eggbeater (with reflector) , it works best on higher passes. If you run out of patience, you might consider the Antennas.us QFH. It was also reviewed positively in QST but I don’t own one. And lastly, omnis are small and simple, but you really need a preamp to avoid a terminal case of frustration. I use the ones from ARR with good results. Mike ___ Sent via AMSAT-BB@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member? Join now to support the amateur satellite program!

[amsat-bb] Re: Quadrifilar Helix antenna question
Hi Norm, N3YFK Are you sure that your Antenna Analyzer Times T-100 is reading a correct VSWR and R+/-jX impedance at 435 MHz ? My MFJ-269 connected to a professional 50 ohm termination goog up to 18 GHz reads VSWR = 1.2 :1 but unfortunately the MFJ-269 do not read R+/-jX impedance above 144 MHz Do not forget that to get RHCP the helix must be winded lefthand and on reverse to get LHCP the helix must be winded righthand. In addition,depending on how you connect the four terminals of the loops into the infinite balun you can get or End-Fire radiation or Back-Fire Radiation. I am interested on your experiments using your data to put it into the Smith Chart and check BTW on 70 cm using half-turn quadrifilar (two half-turn bifilar loops). with dimensions that yield the correct phase relationship with a loop wire diameter of 0.0088 wavelenght as follows and suggested by Walter Maxell W2BU and using: Smaller loop: D = 0.156 wavelenght lenP° = 0.238 wavelenght Perimeter= 1.016 wavelenght Larger loop: D = 0.173 wavelenght lenP° = 0.260 wavelenght Perimeter = 1.120 wavelenght I got a return loss of -20 dB about a VSWR of 1.22 : 1 at 435 MHz as measured on my HP8555A Spectrum Analyzer usind a well calibrated HP11692D directional coupler. 73" de i8CVS Domenico - Original Message - From: To: "AMSAT-BB" ; "i8cvs" ; "William Leijenaar" Sent: Monday, January 23, 2012 3:03 AM Subject: Re: [amsat-bb] Re: Quadrifilar Helix antenna question > Gentelmen: > Thank you for your input.

[amsat-bb] HI4/AJ5C
Hi all, Looks like I have run the gamut of all the usual suspects as they say. Is there anyone else that needs a contact with me on AO-27? Please email me direct at aj5camsat.org and let me know. I will be operational until Feb 8th. Most contacts now are duplicates.. Remember, QSL cards will be sent out when I get back to all that made a good contact with me. NO SASE NEEDED. Will also upload to LoTW and Eqsl. 73, Bob HI4/AJ5C ___ Sent via AMSAT-BB@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member?

[amsat-bb] m9 class solar flare
My garage door malfunctioned when I tried to activate it for the first time since the m9 flare. It is programmed to limit by a series of button presses on the remote control to set its limits, and the code changes with each press to activate over a billion new codes...It is a Liftmaster Professional.. Peter, Dom, Franklin, or anyone, am I way off base by making the assumption that the charged particles from the flare could caused the malfunction?? Or has one of them hit one of my 90 year old brain cells??? 73, Dave, WB6LLO dguim...@san.rr.com Disagree: I learn Pulling for P3E... ___ Sent via AMSAT-BB@amsat.org.
