Not currently operational for satellite but checkout my antenna arrangement:
http://www.kl7uw.com/sat.htm

I have a single top section of Rohn-25g tower mounted on a hinge base
with the B5400 mounted just above the tower.  The old set up had too
much wind area and weight too high for the aluminum mast (see the
bent over photo).  For antenna  work I just unbolt and layover the
tower on its hinges using my lawn tractor holding a guy wire.

New trimmed down array is with part of M2 436CP42 array (using 26
element back part of boom) and a 2M7 yagi from M2.  I also have a
small 2.4 GHz patch antenna not is use.

I had all this mounted on the roof of our old house on a TV tripod
tower (no photos).

Some day I will get it all restored and figure how to utilize my K3
and KX3 for a mode-UV station.  I am too involved in eme at present
and running small ham business.  Hoping for a Heo or Geo style
satellite for the future.

Look at your display on the TS2000.
Above the first digit on the freq display you should see ?PRE? meaning the
preamp is on.
On my TS2000 setup with the preamp on I hear all sats just fine.
But every now and then I notice that the ?PRE? is not on and as a result I
don?t hear the sats or they are very weak.
I have now got into the habit of looking for the ?PRE? every time I turn on
the sat tracking program (MacDoppler on my Apple computer).
This may be the only problem you are having and is easily fixed.

More from the stupid question file: What kind of power supply are you
using? Is it providing enough current?

I don't trust the power output indicator on a radio. Use an IC-7000
and an 857d portable. The 857d has a voltmeter that indicates B+.
Keeping an eye on it before, duing and after key down gives me a feel
for what the battery is producing.

Could also be desense. If you've got a cavity handy and a way to make
a  return loss measurement (tune it), it's worth a try! My Times
Technologies T-100 has this function. Present generation is 200$ on my
fave-rave auction site.

Find the bug, prove the bug, shoot the bug.

Dear AMSAT community members,





This is a reminder email for my Security Survey. So far about 25
participants have completed the survey, and if you have, I am very

grateful. I would ideally want about 100-200 respondents, but I have had
about ~50 participants on the previous surveys. If I could get another 15-25
participants that would be great. At present I plan to close the survey next
Monday.



I was informed that the Pro, Con, Neutral question is difficult to take
because of how Qualtrics has implemented the question and because I added
definitions to the terms that take up more space. Unfortunately, I cannot
change that for this survey. I have similar question types on the remaining
two surveys and I have switched to a mouse hover for displaying the
definitions. I will also include them in a pdf for those taking the survey
on a touch based device. My apologies. I show about 16 partially complete
surveys, if that is all of the survey you planned to take then that is fine,
if want to finish it you can by visiting the link with the same browser, as
long as you have not cleared you cookies you should be able to resume. Thanks.



There is a chance to win some gift cards. Please see below for more
information and the link to take the survey. The survey should only take
about 10 minutes. Thanks.



Please note that the link is anonymous, so you are getting this reminder
even if you have already taken the survey. I would like to thank everyone
that has participated thus far, I really appreciate it, I know it is an
inconvenience and that everyone is really busy.



The second part of the survey has background questions that will give
context to your answers. Try to fill the background out the same way if you
take more than one of the surveys.



You can you use the link below to access the Security Survey.



https://usu.co1.qualtrics.com/SE/?SID=SV_cwoPwnnqVbUG1hz



Answer as many of the questions as you want and as much of each question as
you want, partial surveys may still be very helpful. At the end of this
survey, you will be redirected to a webpage that asks for an email address.
You must enter a valid email address to be considered for survey drawings or
the overall survey set drawing.



We are currently on the 4th survey, Security.



You have a chance at receiving a gift card for participating in this survey
as well as a chance at receiving a gift card for your overall participation
in the entire survey set. There will be 2 winners of $25 gift cards for each
survey and 2 winners of $200 gift cards for the survey set.



The surveys are as follows and will be distributed in the following order:
(participate as you see fit)



Core Concepts

Development Preferences

Open Systems Architecture and Modularity

Security  <========= We are here =========

Reuse, Interoperability, Portability, Code Complexity

Network



V/R,

Brandon Shirley

See
http://brandon.bluezone.usu.edu/Files/LOISpaceSoftwareAttitudes_Final.pdf
for the Letter of Intent (LOI) that explains your role as a participant
should you choose to participate.



This is a legitimate request for you participation, if you have any
questions about the validity of this email you may refer to the Letter of
Intent, contact Brandon Shirley via email at b.l.s@xxxxxxxxx.xxx.xxxx or
contact Utah State University's Internal Review Board administrator at (435)

I thought the TS-2000 had all the doppler correction built in.   Why aren't
you using that since your laptop isn't attached to the radio????

This is a common misunderstanding about radios with a "Satellite mode."
  These radios typically just lock VFO's and perform normal or inverse
tracking but they cannot automatically adjust to the correct frequencies
for Doppler shift.  You should use external computer control to do that
accurately.

In fact, if you manually lock VFO's and try to have a QSO with someone
on a LEO satellite, you will quickly find yourself drifting away in
frequency from the other station each time you move the main VFO.  In
general, this is a bad practice.  If you unlock the VFO's and tune
either the uplink or the downlink (depending on satellite mode,) you'll
be fine.

It is best to adjust the higher of the two frequencies when manually
tuning.  This is the common practice known as the "one true rule."
Locking the VFO's will typically inhibit your ability to adjust one band
or the other separately unless you are depending on RIT/XIT.

The Satellite Mode found in older rigs is a blast from the past.
Specifically P3 birds like AO-10 and
AO-13. It depended on the Doppler shift being relatively constant (but not
necessarily small) over a
reasonable period of time. You could sync your uplink and downlink, and then
tune around with the
uplink automatically correcting. Over much of the P3 orbit you only needed
to resync every 15-20
minutes or more. By comparison, with LEO birds the Doppler shift changes
fairly rapidly throughout
most of the pass, thus invalidating the basic assumption of the integral
Satellite Mode. Fortunately
software such as SatPC32 and MacDoppler will work for any orbit. Lacking
that, or when operating a
satellite such as AO-73 where the LO drifts a bit, purely manual tuning is
more of a necessity than an
option.

Hi
Doppler shift depends on where you are (on earth) relative to the satellite.
A radio cannot know this, also not a TS2000.
This is what software like satpc32 is used for.
What a TS2000 and some other radios can do is apply a fixed ratio between
uplink and downlink of a transponder. Excluding doppler.
Btw also excluding eg a freq shift (drift) during a pass like AO73 has. That
is something also satpc32 cannot compensate for.
Enjoy the challenge!

Didn't think of that, will give it a go next time, hopefully later tonight.
Thanks

Look at your display on the TS2000.
Above the first digit on the freq display you should see ?PRE? meaning the
preamp is on.
On my TS2000 setup with the preamp on I hear all sats just fine.
But every now and then I notice that the ?PRE? is not on and as a result I
don?t hear the sats or they are very weak.
I have now got into the habit of looking for the ?PRE? every time I turn on
the sat tracking program (MacDoppler on my Apple computer).
This may be the only problem you are having and is easily fixed.
