Re: EggBeater

by Bill Dzurilla

Steve, I have both a commercial and a homebrew Eggbeater and am disappointed with both, especially in light of its rather high price. Connected to my IC-7000 via an ARR mast-mounted preamp, performance is far less than with an HT and an Arrow. Guess an omni can't cut it, at least not from my QTH. Maybe if I could get it up higher, clear of all roofs, it would do better. I can make contacts at relatively high sat elevations, but can do just as well with a $10 dual band ground plane. My friend has an Eggbeater and the same preamp at a clearer QTH, and he hears substantially better, down to 10 degrees elevation in some directions. Good luck and 73, Bill NZ5N > > Hi Steve, > > > > It is surprising to read that you are not hearing > anything.

Re: true duplex radios

But the ability to crossband repeat doesn't automatically mean that a radio can monitor a satellite's downlink while transmitting to it .... -----Original Message----- From: "Andrew Glasbrenner" <glasbrenner(a)mindspring.com> Subj: Re: [amsat-bb] Re: true duplex radios Date: Mon Jun 1, 2009 12:55 pm Size: 467 bytes To: "Clint Bradford" <clintbrad4d(a)earthlink.net>,<amsat-bb(a)amsat.org> > Really?

How else would it be able to cross band repeat?

G-5500 and LVB tracker question.

by racer5039

I have the G-5500 and a LVB Tracker on my antenna set. I have noticed that when the pair are just setting there the LVB tracker will loose its place. By that I mean if the G-5500 box is at 180* the LVB will start out at 180 but as it sets there it will soon be at 178, 174, 172 and so on. I also noted the meter on the g-5500 is going down too. Where do I start looking ? Marv N0FJP

Original 13 Colonies update

by n3tl＠bellsouth.net

Hey everyone, I've just heard from Gary, N2AUO, who is interested in activating Pennsylvania on the satellites during the Original 13 Colonies special event this week. That gives us 10 of the Original 13 Colonies that will be active on the satellites during this event! Thanks to Gary for his interest in participating. At the request of the event's organizer (Ken. KU2US), those of us active on the satellites will be IDing with our own call sign/special event call. For example, I will be IDing as N3TL/K2G. I'll add that I'm the station in Georgia for the special event, just to be clear. Ken also has advised that he is adding a special satellite designator to the certificates for those who earn them via satellite contacts. Thanks to him for doing this. For the latest information on the Original 13 Colonies Special Event, please go to www.QRZ.com/ku2us. The event begins at 1300 UTC July 1 and ends at 0359 UTC on July 5. 73 to all, Tim - N3TL

Predict is supposed to run on OSX, but I don't know anybody who's tried it.
