Elizabeth Clark, SK
by Robert McGwier 14 Jun '11

14 Jun '11

I know everyone will be saddened to hear that Elizabeth Clark has passed away after a long illness. My heart is breaking for Tom especially but all of us in the AMSAT family as well will miss her. Elizabeth was one of the most kind-hearted souls I've met and treated me more like a son than a friend. In fact, since I left high school, I spent more nights as a guest of the Clarks than I have with my own mother. I will miss her terribly. She rests with the angels now. Bob -- Robert W.

Better work that HF DX while you can!

Interesting results from a major scientific meeting about why the sun is doing what it is. Bits and pieces of this have been floating around for a few years, but it now seems to have been made into a coherent theory. http://preview.tinyurl.com/6cf2hoz The punch line: >>"If we are right, this could be the last solar maximum we'll see for a few decades," Hill said. "That would affect everything from space exploration to Earth's climate." Of course when you primarily work satellites, your motto is: "Sunspots? We don't need no stinking Sunspots!" ;) OTOH, this does have implications FOR satellites in terms of radiation effects, not all of them good. As with all scientific theories and predictions, we will have to wait to see whether it pans out. 73s, Alan WA4SCA

Re: Nova Keps Update

Hi. This is causing some problem here too. Is it possible to download and then paste them into the NOVA database? - Perhaps as text files?

You'll notice that your browser uses "https" at the start of the URL. The secure access isn't currently implemented in Nova. According to the NLSA website, they are working to adapt Nova to this change and will release a new version. 73, -Daniel, VA3KKZ On 06/14/2011 03:53, Sven Arne Astrup wrote: > Hi! > > > > I know this question has been asked before! > > Could someone give me a lesson on how to get the NOVA Internet Keps Update > to work again from the Space-Track homepage. > > There is no problems logging in on the Spacetrack homepage using my username > and password. > > > > 73 de Sven LA6KJ

Hi! I know this question has been asked before! Could someone give me a lesson on how to get the NOVA Internet Keps Update to work again from the Space-Track homepage. There is no problems logging in on the Spacetrack homepage using my username and password. 73 de Sven LA6KJ

Re: G5500 change voltage supply
by Bill Dzurilla 13 Jun '11

13 Jun '11

I just arrived in Europe with a G5500 and was successfully able to convert the controller to 220v simply by moving the wire connected to pin 2 on the KT-30 transformer to pin 3. That's all it takes. If EA4CYG's wire is on pin 3, I would guess that someone has already converted it to 220v operation (perhaps without changing the plug to a European connector?). To be sure that you connect to the correct pin, measure the resistance with an ohm meter between pins 0 and 2 and then 0 and 3. The resistance between 0 and 3 should be significantly more (almost double) the resistance between 0 and 2. 73, Bill NZ5N/OM3BD PS - I am now QRV from OM land on HF but not yet on the sats, due to some antenna problems. --- On Wed, 6/1/11, Bill Dzurilla <billdz.geo(a)yahoo.com> wrote: > From: Bill Dzurilla <billdz.geo(a)yahoo.com> > Subject: RE: [amsat-bb] Re: G5500 change voltage supply > To: amsat-bb(a)amsat.org, "Dee" <morsesat(a)optonline.net> > Cc: ea4cyq(a)amsat.org > Date: Wednesday, June 1, 2011, 1:43 PM > The pdf say "G5500" in handwriting > and I know a guy who says he did this mod on a G5500. > But obviously the KT-30 must be a different transformer. > > 73, Bill > > --- On Wed, 6/1/11, Dee <morsesat(a)optonline.net> > wrote: > > > From: Dee <morsesat(a)optonline.net> > > Subject: RE: [amsat-bb] Re: G5500 change voltage > supply > > To: "'Bill Dzurilla'" <billdz.geo(a)yahoo.com>, > amsat-bb(a)amsat.org > > Cc: ea4cyq(a)amsat.org > > Date: Wednesday, June 1, 2011, 1:24 PM > > Look closer--Wrong rotor and I > > imagine you jump the other connections > > together to have the voltage correct. > > Again, Check the G5500 manual. > > Dee > > > > -----Original Message----- > > From: amsat-bb-bounces(a)amsat.org > > [mailto:amsat-bb-bounces@amsat.org] > > On > > Behalf Of Bill Dzurilla > > Sent: Wednesday, June 01, 2011 12:53 PM > > To: amsat-bb(a)amsat.org > > Cc: ea4cyq(a)amsat.org > > Subject: [amsat-bb] Re: G5500 change voltage supply > > > > Here is the mod to change Yaesu rotors to 220v: > > http://www.hamcity.com/store/pc/catalog/pdf/220vconversion.pdf > > > > But perhaps yours has a different transformer if it > uses > > pin 3 for 117v.
