The Internet Archive Wayback Machine has that site. In fact, you can
go into the archive and see the site as it was over the past several
years:

http://web.archive.org/web/*/http://www.ultimatecharger.com

I didn't see images on several of those pages in the archive, but the
text was there.

Even though the Subject: line of some messages in this thread may have
the call W0MLD, I thought we were talking about Robert W0LMD - the guy
who had the www.ultimatecharger.com web site.  The comment about his
QRZ.com entry being last updated in November 2008 would match up
with W0LMD's entry there.  W0MLD isn't currently in QRZ.com.

Hi everybody,

I finally did my first SSB bird this morning using VO-52. The winner
is NL7VX Steven.

The experience was incredible !! Using SSB sat is a little bit tricker
for beginner..... but FUN!!

I will try as soon as a pass will be enough high for me.... And I will
also keep learning how to tweak everything around me in my shack !!

Best 73 !!

Some General Guidelines to Working the Birds with Omni Antennas:
(My opinion for what it's worth; others may disagree.)

A lot of people are using omni antennas.  Some use
preamps and some do not.  The important thing to remember
when using omni antennas is that you will be getting into
the bird much better than you can hear it, if you can
hear it at all. A preamp will really help.

If you have a full duplex radio and can't hear yourself on
the ssb downlink, there's a problem.  If you can hear others,
try calling them and see if you can make a contact.  Don't
call CQ if you can't hear yourself.  You may be calling on
top of a qso and if you are not doppler controlled, you will
likely drift into a qso and cause interference.  If you hear
others on the bird, try to find yourself and determine your
offset.  Setting your uplink and downlink manually is challenging
but not impossible.  Use a program like SatPC32 to help you
determine what tx frequency corresponds to the receive frequency.
Ultimately, use the program to control your radio.  Once you calibrate
your uplink to your downlink, you will make more qso's.  Make
sure your computer clock is set to a few seconds of the correct time
and your keps are current.  If these are not set, you will not have
the proper doppler control, especially when the bird is overhead and
the frequency is changing rapidly.  If you can only manage to change
one of the frequencies, change the one that is higher (e.g. tx (UHF)
on VO-52 and rx (UHF) on FO-29).  The UHF frequency changes much
faster than the VHF frequency.

On the FM birds, don't announce yourself unless you are full
duplex, can hear yourself and there is little or no activity
on the bird.  Wait until you can hear other stations and then
call someone you can copy.  They will likely come back to you.
Once you make a qso, others will call you so pay attention.  If
you are in an inactive grid, expect a pileup.  Use a recorder
so you don't have to write anything down.  Don't disappear after
your initial qso.  Stay with it as long as you can hear.  You
will make more qso's.

There is always activity on any daylight pass of AO27 and AO51.
If you don't hear anyone, you are likely not hearing the satellite.

As the bird comes over the horizon,
adjust your fm rx frequency 10 KHz higher than the published
center frequency.  As the bird moves toward you, lower the frequency
in 5 KHz steps.  The bird should be on the center frequency when
overhead and then -5KHz as it moves away and then -10KHz as it
gets closer to the horizon.  No computer control is necessary on
the FM birds.  When the audio sounds a little distorted, it's time
to change the frequency.  Use your ears; a computer is not necessary.
It is not necessary to change your uplink (145 MHz) tx frequency.

Working the birds with omni antennas is challenging. As long as
you know your limitations and operate accordingly, you will be fine.
But don't expect to be able to hear very well.  If omni antennas
worked that well, everyone would be using them, and there would be
a lot more than 21 stations that have 350 or more grids confirmed
on satellite VUCC.

When you define a Satellite within HRD v4 and also v5 you have the option
to select for frequentie and doppler correction:

- Repeater / Split or
- Linear inv, transponder

What should I choose when defining for example SO-50, AO-51 or AO-27?

I have no problem with AO-7, VO-52, FO-29 etc etc.

The reason for asking is, that I have a lot of problem with working SO-50
in the combination Yaesu FT-847 and HRD Satellite Tracking. At first I
thought it was an CTCSS problem, but it seems that I am of frequentie :(

Any help would be appreciated,

Hi Nigel,

Dragonsat was the designation for both Aggiesat2 and Bevo1. They were
ejected together from the SSPL, but it appears that they failed to separate.
Here is an official update:

-----------------------
Still no signals from BEVO1, although beacon packets were heard from
AggieSat2. The current theory on the state of the satellites is that
only partial separation occurred. The inhibit switches keeping the
satellites powered off have been closed, allowing the satellites to
boot up. However, it is likely that the antennas did not deploy
correctly, leaving the antennas disconnected from their respective
transmitters. AggieSat2 transmits with 1W of power so it is easier to
hear, while BEVO1 only transmits with 200mW during beacon mode.
-----------------------

UT Austin has also posted some pictures here:

Thanks for all your help!

Hello All,

Its also a pity they can't all agree on the same satellite:

NORAD number 22825

Hello AMSAT list,

I have a problem caused by static electricity building up on my two helix
antennas (23 cm and 13 cm). Two converters have already been zapped, so I
have to do something about it.

What measure would you recommend to avaoid statics building up on helix
antennas?

Does anyone have experience using the shorted quarter-wave-stub mentioned in
"The ARRL Handbook 2008" pages 23.20-21?

When you define a Satellite within HRD v4 and also v5 you have the option
to select for frequentie and doppler correction:

- Repeater / Split or
- Linear inv, transponder

What should I choose when defining for example SO-50, AO-51 or AO-27?

I have no problem with AO-7, VO-52, FO-29 etc etc.

The reason for asking is, that I have a lot of problem with working SO-50
in the combination Yaesu FT-847 and HRD Satellite Tracking. At first I
thought it was an CTCSS problem, but it seems that I am of frequentie :(

Any help would be appreciated,

And of course outside of North America 902-915 MHz is used for Cell Phones and
satellite signals don't respect national boundaries.

You raise the question of licensing 'in-orbit' devices and the potential
legality of such.

I guess, like some others, I'm unclear how licensing for such projects,
Cubesats and the like, comes about?

The recent announcement of the UK's FUNcube project will presumably require
a licence from OFCOM if it is to be truly UK attributed.

This will surely be a first for them (OFCOM) in the amateur field and in an
area of amateur licensing not defined in the current regulations.

Hi Lars.

Can I suggest:

1) A 47k resistor across the input of your converter. The static will have
a very high impedance and I've found 47k will remove it without increasing
the noise figure of your converter.

2) For really severe cases.  An inductor to ground. An 0805 or smaller
device. Something that presents a couple of k ohms at the frequency of
interest
would be OK.  Or perhaps a high pass filter designed for 50 ohms with an
inductor to ground. Cut off frequency at 30% lower than 23 or 13cms

Thanks

David

Hi Michael,

Not sure if you got a reply, but for C3i try contacting Owen, K3CB.

I also thought at one point, M2 had the plastic insulators and stainless
keepers as they were doing some KLM stuff. I don't see anything in their
catalog, but might be worth a call.
