Happy New Year all
This is probably simple, however, I need a quick and simple way of
determining my uplink frequency given a specific downlink frequency.?
Usually I will just send a few dits to find myself.? When trying to work a
sked footprint edge to edge I need to be at the right frequency at the right
time, without hunting around for myself.? I am refering to AO-7

Bob,
SATPC32?
As long as the spacecraft systems are good, and AO-7 will wander a bit, I
can always find myself. A quick tweak requiring a few seconds, and I am in
business.

Hi Bob,
Use SATPC 32....once set for AO7 it will be within your rit knob in
seconds....

I concur with Alan regarding SatPC32.

Want to see something old? Check out what the Hubble program just released -
shots taken last August that show galaxies between 12.9 and 13.1 billion
years old. Considering the universe is probably about 13.5 to 14 billion
years old, this is incredible.
(Insert your own "old age" joke here.)
http://hubblesite.org/newscenter/archive/releases/2010/02/
Hubble used the newly installed Wide Field Camera 3, which allows it to see
near-infrared wavelengths in the electromagnetic spectrum. This allowed the
telescope to observe light from the very beginnings of the universe.This is
because the expansion of the universe distorts the ultraviolet and visible
light from these galaxies over the course of their unimaginably long
journey, pushing them into near-infrared wavelengths.
These are some of the final images the Hubble will send back, as it's being
replaced by the James Webb Telescope in 2014. Which is both sad an exciting,
as the Hubble has shown us so much of the universe but the Webb will show us
even more.

Hello All,
A few months ago, I had stopped working the AO-51, why I could not listen me
on the downlink. I was a little frustrated because I can't heard me via
AO-51. I thought it was because of software problems and changes to the
settings of the satellite. There are 4 days ago, I discovered that the
problem was in one of the cables from my UHF antenna. That would not let me
listening to the stations that called via AO-51. In these last four days in
several orbits I was able to keep QSO with our friend Hugo - EA8HB in Las
Palmas Island with strong signals. And today in orbit 29,028, at 21:11 UTC,
I heard the N1EL calling me, which is 3.466.9 miles of my station. I see
that the AO-51 continues "brave" in the space. Congratulations to the AO-51
Control Team by incessant work.

That is pretty much state of the art, even now. Take a look at the
photos of PCSAT at http://wa8lmf.net/bruninga/pcsat.html
You can just make out the inch markings on the yellow tape measure in

Hi!
I will have an AMSAT table at the ThunderBird Amateur Radio Club's
WestFest hamfest in Glendale, Arizona, on Saturday 9 January 2010.
The hamfest will be in the Activity Center on the Thunderbird
School of Global Management campus, from 0700 to 1200 local time
(1400-1900 UTC). More information about the hamfest, including a
link to a map showing the hamfest site, is available at:
http://www.w7tbc.org/Westfest.html
WD9EWK will be on the air with demonstrations using a variety of
satellites throughout the morning. The tentative schedule, with
all times in UTC, is as follows:
1301-1315 UTC - AO-51
1441-1452 UTC - AO-51
1553-1604 UTC - VO-52
1632-1644 UTC - SO-67
1729-1741 UTC - VO-52
1759-1812 UTC - SO-50
The first AO-51 pass takes place before the hamfest officially
opens, but I will be on the air from there with whatever audience
happens to be around the hamfest site at that hour (possibly
others setting up their tables/booths inside the building. The
hamfest site is in grid DM33vo.
Thanks, and 73!

Hi Bob,
Whatever the satellite, if you're trying to stretch the footprint, your sked
is always going to be at the peak of elevation, for that fleeting moment
when the satellite is a few degrees above the horizon. That means that
you're always going to be at zero doppler shift, and the math will always be
the same. Find yourself once at TCA on any pass, and lock them in. The
numbers will be the same for your sked.
Good luck,
Greg KO6TH

I wouldn't agree with that statement at all. Most of my long haul
contacts on AO-7, FO-20 and 29, and now HO-68, are right after AOS or
just before LOS, certainly not at TCA. Use my recent QSOs on HO-68 with
Argentina as an example. Even when I work Europe on AO-7 it is at the
beginning or end of a pass...not the middle.
Bob, SatPC32 will show you the frequency with Doppler shift, and the
Doppler shift. A little subtraction or addition and you have what you want.

I think there was an expectation that FO-29 would emerge from eclipse

For the tube, I would recommend a QQV06-40 if you can find one.
Was used extensively in the VHF mobile radio market (both for mobiles in the
1960s and base stations)
Will need a 600V anode supply, 250V screen grid supply and 6.3 or 12.6V
heaters.
Can't find a specific design, I would just put the bits together and see
what works.

I would try to locate old QSTs or Amateur Radio Handbooks that contained
such circuits. Tubes such as 6146, 829, etc. were good candidates. Also
the 4x/4CX150 would give up to 100+ out with just a few watts in. Newer
handbooks or magazines still provide you with he necessary theory to
build one from scratch. Building a tube amp is quite simple, just need
to have 300 - 1000 volts dc supply based on tube and power out. Also,
usually a 6.3vc transformer for filaments. Nothing wrong with tube amps.
I have an old Johnson 6n2 unit that runs about 150 watts. Neat old rig.
Find an old rig as I mentioned above and go online to the various manual
websites and obtain the manual for an old rig. You can use that as your
example.

Agree, and even old tubes like the 2E26, 832, etc are good tubes for this
power requirement, but the problem is that tubes from that vintage are
usually "sour" by now, if you can even find one. I'd suggest looking for an
'Oldtimer' whom never threw anything away, like my dad (SK) and you might
luck out with tubes, caps, tank circuits, etc. Enjoy the true meaning of Ham
Radio........building your own......that is what's missing in this hobby
pretty much nowadays, as now we are pretty much appliance ops..

Subject: [amsat-bb] Re: Winter Project
I would try to locate old QSTs or Amateur Radio Handbooks that contained
such circuits. Tubes such as 6146, 829, etc. were good candidates. Also
the 4x/4CX150 would give up to 100+ out with just a few watts in. Newer
handbooks or magazines still provide you with he necessary theory to
build one from scratch. Building a tube amp is quite simple, just need
to have 300 - 1000 volts dc supply based on tube and power out. Also,
usually a 6.3vc transformer for filaments. Nothing wrong with tube amps.
I have an old Johnson 6n2 unit that runs about 150 watts. Neat old rig.
Find an old rig as I mentioned above and go online to the various manual
websites and obtain the manual for an old rig. You can use that as your
example.
