The server was moved to a new location, and the IP address changed. You
might have better luck by flushing your DNS (`ipconfig -flushdns` I
believe), or by going straight to the IP (
http://169.228.66.5/amsat-new/index.php).

If you can, call CQ. That's how I got the 1 CW QSO I've ever gotten on the
sats. I would have had 2 if I hadn't messed up the VFO.
I've really got to get my sat station set up again so I can try again... I
love the somewhat warbley sound of CW on AO-7. :)

That warbley or fm'ing sound is if we run too much power or there are
several people on at the same time.? Those poor 36 (I think) year old solar
cells are working? really hard.? Try to keep the power to a minimum to
maintain communications.

Getting to amsat.org works for me this morning.
Yesterday evening between 1800 through perhaps 2200 Central time I could get
to amsat.org on the PC that uses OpenDNS but the laptop running the default
Comcast DNS gave me the server not found error. Both DNS are working now
over here.

I have been calling CQ. From the reports I am getting, I am not hearing the
downlink as well. I can hear myself and I lower my power until I can barely
hear myself. Better antennas will improve this. I did work NL7VX in the
Washington DC area tonight.
AO7 comes up here in Tampa at 8:30 local time and it looks like the pass
will cover a good part of the US so maybe I will make more contacts tonight.
Thanks to all for your helpful comments. This really is magical stuff. I'm
looking forward to making lots of CW contacts during Field Day.

I am new to the satellites.? Got to where I can hear my downlink if the bird
is
higher than 15 degrees.? My question is about handling the doppler shift.
If you do not have a sat program automatically correcting you rig frequency,
what is the most common or preffered technique?? 1 - Hold the TX steady and
adj
the RX for doppler or 2- Hold the RX steady and adjust the TX for doppler?? I
know this must be a basic question but I am learning.? Thanks,

Adjust the higher frequency of the two you're using.

Hi!
Good question.
Hold the TX steady and adjust the RX. If You adjust TX, the other guy have
to adjust also his RX and then his TX... a mess.
It is much easier if everybody adjust only his own RX and keeps TX steady.

Hi Doug, KA9DLP
Hold the RX steady and adjust the TX for doppler.This is what I did
manually from OSCAR-6 and I do actually on VO-52, FO-29 and
OSCAR-7

Hi Satelliters,
?
Might cause some flames with this? but here goes:
?
With a good few years of operating on the SSB sats, AO's-10,13,40, RS10,
FO-20,FO-29?and?98 countries confirmed I can agree totally with the "one true
rule" in theory. When?stations at each end of the QSO use the method it works
flawlessly, I have done it with QSO partners using?Fod track and with
Instantrak
computer Doppler correction, but there is the problem.
?
Many of the stations that you want to work will be using manual tuning
methods,
so as you maintain your frequencies at the satellite, according to the rule,
your QSO partner will have to search for you. Then when its your turn to
transmit he will have to search for you.
?
The practical solution that I and I believe most of the ops. I have worked
seem
to use is to have short overs and to adjust frequencies the TX to try and?keep
the QSO in a fixed spot on the receiver.
?
Following the other "often recommended" method of adjusting the higher
frequency
irrespective of its function, up link or down link, cause QSO's to drift
across
the pass band causing problems for other users.
?
The other point worth making for newcomers to the SSB birds is to start on the
easy passes/satellites first to get the knack of manual tuning. For example,
try
VO-52 with its 2m downlink,?and to pick low elevation passes where the rate of
change?of frequency due to Doppler shift is less. Don't expect to get it right
with?near overhead passes of FO-29 until you have delevop? your skills.
?
We were all beginners once so don't be afraid to have a? go and make a few
mistakes.
I am pleased to say that in my experience the SSB satellites have a great user
community who maintain high operating standard and welcome new ops.
?
Have fun on the birds
?
73 John G7HIA

Lamenting the loss of our lovely HEO birds, Happy Days !!

Hi Ted,
Here is one to bookmark:
http://www.amsat.org/amsat-new/echo/CTNews.php
When we're able to turn it on, you can work it using:
145.880 FM up, no tone
435.150 FM down
73,

A rookie observation?.
That article was written in 1994 ?well prior to the state of the art in full
doppler correction. I use MacDoppler for adjusting the VFOs and it happily
adjusts both of them. The ONLY time I run into a problem where the received
station is moving is when it is clear someone is NOT using full doppler
correction.
I would humbly submit that this being 2011 and both SatPC32 and MacDoppler
handle full doppler correction, the exception should be the One Tune Rule
and the norm should be full doppler correction. I know that when I work
someone that is also using full doppler correction, it is a joy as the radio
just happily stays tuned and we move during the whole pass.
Is the state of the art still such that we are all using radios that do not
support full doppler correction?
I will put my flame suit on now?
73,
Tom
