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

We have met the enemy and they are us. WE need to do something. Yes, $15m is
outta reach, but isn't there a cash prize for the first on-commercial moon
landing?

I couldn't agree more - we don't need more of the same.
If I want to sit back and have a two hour rag-chew with someone on the other
side of the planet I will use Skype or my cell phone!
Dreaming about what *might* be in space is a fun exercise. Actually doing
something about it requires sending things to LEO because reality has
dictated that's as far as we can afford to go.
How's about we use some of that frustrated *imagineering* to come up with
interesting new concepts at LEO? We don't need any more FM repeaters buzzing
overhead, but what about more cameras downloading HD images, scientific
payloads that monitor the ongoing climate change, payloads to study the
Earth's magnetic field, etc. etc. Our own 'Twitter' messaging network from
space...?
The Apollo 13 creed of "failure is not an option" has completely infected
the brains at AMSAT and this list. You want something at HEO or on the moon,
cut a check for $15 million dollars and let's get on with it. Been waiting
since 1996 for another AO-13 and I am getting too old to keep waiting.
AMSAT is becoming completely irrelevant as it strives without success for
the impossible mission and exhibits a shocking amount of leadership
malfesance as it stubbornly refuses to recognize and adapt to realities in
the launch business.
I know, I know maybe NEXT year someone rich will die and leave us a boatload
of cash. Or the bankrupt US government will suddenly cough up a billion
dollars for some orbiting emergency communication system. In the meantime we
have to stifle the truth because it might blow yet another *secret* deal
that's in the works and *almost* a done deal, so let's not complain publicly
and ruin it.
Heard the stories, heard the lies, got all the t-shirts and ball caps.
Whatever.

Hi Luc,
TLMEcho is the program for LIVE decoding of AO-51 telemetry packets
during a pass. Some telemetry channels are sent via 9600 baud packet
at a regular interval, usually 10 seconds, and TLMEcho can decode
these (using a 9600 baud modem) LIVE as they are coming down.
The new WOD decoder is different--it is used to decode satellite
telemetry data collected (more channels usually) and stored on the
satellite during a whole orbit (usually set for 24 hours). Once the
WOD file is finished, it appears on the PBBS and can be downloaded via
WISP. The downloaded WOD file can then be decoded by DK3WN's new
program after it has been downloaded from the satellite as a big file
(about 180k).
I hope that helps clear things up :)
73,
Mark N8MH

Hi Mark
Is it a new program or a new update for "tlmecho"? I guess it's a new
one but just to be safe.
Thank's

Hi,
I probably missed something.... but on AMSAT website, we are able to buy
the LVB Tracker completely assembled, the bare board without any part or
only the enclosure........
What about a complete LVB Tracker.... but as a kit ??
I don't want to save money, I just like to build, when possible, my
hardware.
Is there a place to purchase a complete LVB Tracker (parts and
enclosure) as a kit instead of completly built ??
Thank for your help.

Hi,
Just thought I'd remind everyone that all AMSAT mailing lists are
archived and past messages are available for search in two ways:
1. Use the Subscription settings link at the end of each message to go
to a web page that has a link to the archives for that mailing list.
2. Search using Google, with the search string
<search keywords> site:amsat.org/pipermail/<list name>
The <list name> part is what appears at the start of a mailing list
subject line; for example, "amsat-bb". If you leave off the "/<list
name>" part, you will search all public AMSAT mailing lists. (Other
search engines can probably do something similar.)

I have built several 13 cm antennas from the site of G6LVB and WK4R all using PVC.
It doesn' get any simpler than WK4R's design. 1 inch sch. 40 PVC and some #14 house wiring. Check out this site.
http://wk4r.com/
If you need some tips, email me. I'll be glad to help.
Here are some other good websites for 2.4GHz helix antennas.

Select 2.4 GHz helix.
3. www.g6lvb.com/
Select quadruple helix for AO-40.

I threw this out there on the eham satellite forum looking for answers
but I'll try here too.
I'm looking for some fairly simple plans for this antenna. Everything I
find either seems to be intended for WiFi or if it is ham related is
full of mathematical formulas to figure length, diameter, spacing etc.
Math was never my strong suit so I'd prefer to find something with the
actual already computed dimensions clearly stated. Preferably in English
rather than metric measurements. I found an article in the May/June 2008
AMSAT Journal that looked promising but there are no hard numbers, just
the formulas and I don't have a calculator capable of some of the
computations, much less being able to work them out in my head. Been a
long time since I was in school!.. hi hi... I have a downconverter I'm
not sure even works and I don't want to spend a huge amount of time and
trouble to be able to test it.
Tnx and 73,
Michael, W4HIJ
