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

Are there any satellites on 2.4 gig so I can check out my old AO-40 dish.

Once again we are approaching the 4th full weekend in June and that
means Field Day.
I have posted the AMSAT 2009 Field Day rules on my website in both pdf
and doc formats.
http://www.amsatnet.com/2009fd.pdfhttp://www.amsatnet.com/2009fd.doc
It will appear in the May/June issue of the AMSAT Journal and at
http://www.amsat.org (soon).

I'm no Java whiz either (my son is the programmer, not me), but my best
guess is that you need to update your Java Runtime version. The program was
compiled on a computer with JRE 1.6.0, so you probably need that version.
The Windows .exe has run fine on all 5 computers I've tested it on, and all
are at JRE 1.6.0. The .jar ran fine on the Ubuntu 8.04 ("Hardy Heron") box
I tested it on, but I did not check the Java version on that machine.
In Windows, you can check your JRE version clicking the Java icon in Control
Panel, or by typing
java -version
on the command line.

Hi George,
I'm kind of dense when it comes to Java applications, but I can't get either
version to run. The Windows version pops up an error box saying "Could not
find main class. Program will exit.", and the Linux (cross-platform) version
says all this stuff, below. What am I doing wrong?
Thanks,
Greg KO6TH

I am working on some a couple of the "Cheap" antennas by WA5VJB, that have been talked about on here.
I am building these for Field Day and th use for some moble work on AO-51 & AO-27 after that.
My question is this, Is the "J" /DE element centered in line with the others or is just the long side in line?
My guess is the long side but thought it better to ask.
Thanks

Yeah, I gotta fix that.... I had set the page up with the original version,
and then when the new version was ready, simply deleted the original files
and uploaded the new ones, and somehow, Google sites didn't handle it right
(even tho the file names and locations are exactly the same...)

Worked Yuri last night on SSB on FO29. He is apparently still in port in EM40.

>> ... Most cigarette lighters circuits have a 15 to 20 amp fuse on
them. That ought to work fine for charging/using with your computer ...
That amount of current can/will destroy sensitive electronic devices.
(20A??? That's more than what an Icom IC-706MKIIG uses at 100W TX
power ... )
Personally, I would never run my laptop off a vehicle's charging
system while the vehicle is running. You won't find many reputable
laptop manufacturers recommending this.
And all power feeds to my radio gear are properly conditioned and
filtered.
If I needed to run my laptop for extended periods on a 12VDC system, I
would use nothing less than a ...
Tripp Lite PVINT375
(although this model comes with a cigarette lighter plug, that
connection has to be one of the electrically most UNreliable for what
we are doing - so the plug gets whacked off and the unit is wired
directly) ... or
Astron Pi-250W
12VDC-to-120VAC inverter made for such circumstances. Wire it in to
your vehicle's 12VDC system, and simply use your existing AC power
supply. Immediate benefit is the ability to power/ charge other
electronic items you may have using regular AC chargers.
There's no need to know the voltage/current/connectors of the laptop.
The laptop's manufacturer already did all that work for you when they
supplied the AC adapter.
Another downfall of using the cig lighter circuit for comms: very
rarely is that line filtered for noise and such. I mean, who needs
that line filtered to heat up a cig lighter? More intelligent cars do
have filtered/conditioned "power ports." But I do not leave anything
to chance, and make sure my equipment is properly protected.
Then there are folks who run their 100W HF rigs through a cig lighter
plug and swear that all's well with the world ...
And so it goes.
