G5400B rotor maintenance

11 Sep 2009

      Adding to Alan's suggestions, may I suggest that when the screws holding the
two halves are replaced, you use Allen head bolts as they are much easier to
remove later. Hex bolts sometimes are difficult to get a spanner on. I have
done that for my rotors
A source for repairs is RotorNorm, who has spares for all types of rotors
and undertakes complete rebuilding if need be, but servicing these are quite
simple

First determine whether it is just a dirty or worn winding in the POT that
is causing needle flicker.  Run the rotator on the bench with an ohm meter
across A2 and A1, then A2 and A3 ( same numbering on the EL - see schematic
) while running full rotation.  Don't connect the 1,2, 3 terminals to the
controller.  If it is smooth and uniform 0-500 ohms there is nothing wrong
in the rotators except your noise problem.  I've found the AZ always noisier
than the EL.
Storing the AZ upside down ( or in fact mounting it up side down as I once
did in error ) is big trouble as water will run into the ball race and
probably rust a few of the ball bearings and compromise the grease.  They
can be replaced easily and new grease installed.  That was probably your
stuck rotator.  It is probably all you need to do to get the noise problem
resolved.  It should at least be inspected to see what damage was done by
storing upside down exposed to the elements as dirt will have been cared in
with the rain.
It is not too difficult to get inside and snoop around.  You can start my
just removing the inspection plate to see the condition of the internal POT.
My experience is that the EL rarely needs to be opened up as it doesn't do
much travelling - at most 180 degrees but I bet most folks don't flip their
EL and so all it does is go up and down 90 degrees most of its life with far
fewer jogs than the AZ.
Below is a link to a rebuild where I replaced many of the metric screws and
did a re-grease for our -40/+40C WX in EN19. The ball bearing were not
replaced as they were pristine. Make sure you have a place for metric
machine screws before you start to open up.  The Home Depots in Canada had
all the metric screws I needed.  For Canadians contemplating a rebuild, I
found Canadian Tire had the largest selection of metric screws followed by
Roma and then Home Depot.  Auto suppliers will also have them for the
"foreign" cars made in NA.

Good luck... Alan

I recently picked up a G5400B AZ-EL rotor unit, which had been down on
ground for sometime. I recall it had been stored upside down outdoors. When
I got it home and hooked it up in the shop, the Azmiuth rotor was stuck, but
some manual help, broke whatever was stuck loose and it started to operate,
even abit noisy. The Elevation rotor is nice and quiet and works fine. I
notice now, after being used for afew weeks, that the noise is getting more
pronounced and also the meter indicator flickers, so I suspect water
probably got into the unit.
Who does repair work on these rotors? I dont dare try it myself, as I know I
would end up with extra parts at the end of the day, even working in a tub.
So, would appreciate any help in finding a business that repairs these Yaesu
rotors..

Robert,
Hurling questions and accusations is easy, but, doesn't seem to help.   
Keeping up with what's going on (the information IS available) and  
PARTICIPATING in the work will provide a solid platform from which to  
speak.
Dive in!
And, let's try to keep the discussion constructive.

What we can do is to live out our lives as best we can with purpose,  
and with love, and with joy.  We can use each day to show those who  
are closest to us how much we care about them, and treat others with  
the kindness and respect that we wish for ourselves.  We can learn  
from our mistakes and grow from our failures.  And we can strive at  
all costs to make a better world, so that someday, if we are blessed  
with the chance to look back on our time here, we know that we spent  
it well; that we made a difference; that our fleeting presence had a  
lasting impact on the lives of others.

As a SuitSat team member, I gave you a brief answer offline and offered 
to get more detail if you so desired. You didn't respond. It's obvious 
to me that you really don't want an answer, You just want to be a 
boring, broken record.
So I'll repeat the simple answer, here, why we missed the suit launch. 
Listen up.
The SuitSat team is made up entirely of volunteers who have real jobs, 
families, and other responsibilities. Hey, we're just pursuing our 
Amateur radio HOBBY - not a professional job. Some of you folks talk 
like we're a Loral or Lockheed.  Did you critics forget that Amateur 
radio satellites are a hobby - not a business?
Well, by golly, along the way technical challenges delayed progress. 
Jobs and families got in the way. Son of a gun - we missed schedules. 
I'm not offering excuses, just offering the reality of having folks on 
the team that aren't getting paid for their fantastic efforts.
Sure, it's not nice to have technical issues show up or to miss 
schedules but in the scheme of things, what have we lost - except maybe 
creditability in YOUR eyes. We now have a new satellite structure more 
suited for what we are trying to do technically - called ARRISat.
The way you've been carrying on, I am so very glad we don't have you 
volunteering - even to stuff envelopes. You'd probably say that we were 
doing that wrong too. Personally, I thought that refunding your AMSAT 
life membership would make me feel better, but on further reflection, 
AMSAT should just keep your money since it is helping fund efforts to 
serve it's members who appreciate what volunteers are trying to do for 
them and their hobby.
And if you think any of your comments have caused the ARRISat team to 
miss a beat on the way to our 2010 launch, then think again. This team 
has tackled and solved technical challenges more significant for the 
future of AMSAT and its members, than ANY of the issues you raise.

Rather than tacking on more replies to the depressing multitude of 
arguments back and forth that have degenerated to the level of 
name-calling, let's try something that is actually POSITIVE for a change.
The AMSAT web pages have tons of information on them. One of the big 
problems of having such a vast store of information is the impossibility 
of one or a small number of volunteers keeping it all current and up to 
date. Please trust me on this. I am the lone webmaster for another radio 
organization, and I KNOW from personal experience how hard it is to keep 
the thing going properly. I have admitted publicly on several occasions 
that I appreciate feedback, and will do my best to make repairs when 
errors or omissions or outdated information is detected.  Unlike the 
experience with the AMSAT volunteers, however, I have actually received 
honest-to-goodness POSITIVE feedback from folks, and it has helped me 
enormously to fix at least the worst shortcomings of the site I have 
volunteered to maintain. I've even had a few people say "Thank You!" to 
me, and it sure feels good to know that my efforts are appreciated, even 
if they don't match up to my own standards of what I wish I could do.
So, here's the challenge to EVERY BLEEPING ONE OF YOU who are now 
reading this message:
1) Find something on the AMSAT web site that needs fixing. According
    to all the flak that's been flying about, that should be no hard
    task, right?
2) Write up a SOLUTION to the problem. Broken link? Find a new link.
    Misspelling? Write down the correction. Poor grammar? Re-write the
    sentence or paragraph to improve it. Outdated info? Find the newer
    info. Etc., etc. I think you get the idea.
3) Go to the "bad" web page in question, and at the bottom, click on
    the link to report "bugs" in the web page.  I realize (as I am also
    a programmer among my multiple self-taught skills) that the above
    mentioned things are not "bugs" in the programming sense, but on
    the other hand, most of the AMSAT pages don't actually compute
    something that a bug would cause to be mis-computed, so I submit that
    the original intent of the author was to use this link to report
    ANY flaw(s) in the page, not only programming errors. If the
    original author wants to contest that point of view, she is welcome
    to come forward and say so in this public forum.
4) Fill out the form that will pop up, including your description of
    the problem AND the solution that you found or created. Hit the
    SEND button.
5) Wait a very short time, and if you did your part well, I am willing
    to bet money that you will find that the web page gets fixed.
There were several things on the Satellite Status pages that annoyed me. 
Having had enough of the troll-feeding, I decided to follow steps 1 
through 5, and, lo and behold, those annoying problems are now history.
I seriously doubt that the prompt action by Drew to my "website bug 
reports" had anything to do with the esteem in which the organization 
holds me, as I am usually lurking around quietly, and saying/doing 
nothing to make my existence even known to AMSAT. I am about as close to 
an unknown member as you can get, yet still be the author of an article 
that was published in an issue of the AMSAT Journal once upon a time. I 
therefore submit that if it worked for me, it will likely also work for you.
Don't believe it?
Go ahead, try to prove me wrong. I dare you.
And have a nice day while you try.

P.S., don't think that the "Life Member" status got me any special 
attention, either. It just means that if they spent my one-time life 
membership fee on cheap whiskey and expensive women, they will have only 
the memories of that experience to enjoy, they don't get to send me a 
bill every year to renew my membership so they can do it all over again!

P.P.S., a hearty THANK YOU to all the people who make this hobby 
possible, especially those who are currently getting flamed recently.

off line and I didnt reply to it.  Sorry.
I will check back and make sure that 1) it didnt by accident go into junk
mail and 2) I just didnt miss it in the regular folders.
We had quite a crush of email over the last few weeks...my wife and I had
shotgunned out a "we are pregnant" email...and I might have just missed it.
I'll look for it tonight...

I've been following this thread passively until now, so brace yourself
because I have quite a few things to say.  I'm 28 and a reasonably new ham,
KJ4JIO (you can look me up but it may require a few mouse clicks...).  I'm
still very new to Amsat and don't know many of you by name or face yet (and
that's probably for the better).  I've had the opportunity to meet a couple
of you here in Orlando, chatting to a few of you through email and talking
to some of you over the phone.
I first heard about Amsat here in Orlando at a LMARS meeting, where one of
your members put on a satellite communications demo.  This was quite
possible one of the coolest experiences of my life.  Before this, I had no
idea that there were so many amateur satellites up in the sky available for
use.  I had no clue that with minimal equipment I could use them.  How cool
is that, really!?!  I didn't know any of this was possible for me to get
involved in at any level.  Maybe it's just another day at the job for some
of you but it's definitely not for me (i'm a bored  software guy at work).
 At the demo, I noticed that the presenter was putting on the presentation:
- on his own time
- with his own equipment
- for well over an hour long
- probably after a lengthy drive
- had an enthusiastic attitude
- didn't complain that the pass was on the horizon and difficult to work
If it wasn't for this voluntary effort, I wouldn't be here right now :-)
That's my history, now on to my main point.  It seems like most of the
bitter sentiment on the thread has been targeted at the amsat website, it's
production, how things get done, etc...  In my experience in software, being
pissed off at something opens up an excellent opportunity for corrective
action.  I get pissed of at code all the time, maybe my code, other peoples
code, doesn't matter... I complain about it, make fun of it, laugh at it for
a few seconds, and when i'm done doing that I *FIX IT*.
Last night, I spoke to Gould about the history of the website and some
related things to get a feel for why things are the way they are.  I have
also been gathering ideas and suggestions from various interested parties on
the bb.  I put together my own list of complaints* in addition to
descriptions of what I would do to improve each of them*.  I set up a
prototype mediawiki server, although i've retired it and am attempting to
see if Joomla would be a little more user friendly on the composition end of
things.  There are definitely wheels spinning in an effort to improve the
situation.  The reality of the website situation is what always happens in
the software world:
- software gets outdated
- it becomes to hard to maintain
- people move on to other things
- the END USER SUFFERS
Please note, i'm not criticizing anyones work on the website here. I'm
certain they did they best with the resources and time they had available
when the work was being done.  I'm convinced what we're experiencing here is
a standard software development life cycle issue, which should not take much
work to improve.
If you have website suggestions, i'd encourage you please pass them on.  By
suggestion, I mean something more helpful than "the website sucks".  A good
example is this:
"Instead of having a Tools, Status and Passes link off the main page, make
one button called "Satellite Tracking" and put all these types of things
within it.  This would help clean up the main page a bit".
I'm very interested (and I know others are too) in getting this type of
input and feedback.
Thank You,
Joseph Armbrruster, KJ4JIO

Bob,
It is a Pryme AL-800 telescoping whip.  About $35 at HRO.

Bill.  As I noted earlier I do owe you the favor of an apology.  You did
send me an email and regretfully it got routed where I did not see it....
I read your piece(s).
What to say.  You folks bit off more then you could chew and missed a
deadline.  That is a foundation of project management no matter if it is
paid or unpaid.  Try and explain it all one wants it means someone (or
group) is not capable of good project management.
I assume that you and the team are confident you can make the next
deployment dates...?

The Pryme RD-98 also works well, and it about the same price. My favorite of
all, however, based on my testing (and I've used the AL-800, RD-98 and
several others) is the Diamond RH-789 (BNC connector; SRH-789 with an SMA
connector) telescoping whip. It's a bit less expensive than the AL-800, but
is extremely wide band. In addition to performing well on the FM satellites,
it really surprised me at how it performed on the shortwave broadcast bands
on a variety of radios.
To Bob - I suspect the AL-800 is the one you're thinking of. It's probably
the most popular and well-known, but there are others out there that also
perform quite well.
The Smiley dual-band telescoping whip is another. Patrick, WD9EWK, sent me
one to try out - and I wore out AO-27 on the first pass I used it ... hihi.
Had seven contacts, which is good for an HT and a whip given the short
window for 27.
73 to all,
Tim - N3TL

The same commands to controllers for bot GS232A & GS232B protocols, but
diferent answers from controllers for position request:
GS-232A - answer?to C2 command is +0aaa+0eee
GS-232B - answer?to C2 command is AZ=aaa EL=eee
GS-232A - answer?to C command is +0aaa
GS-232B - answer?to C command is AZ=aaa
GS-232A - answer?to B?command is +0eee
GS-232B - answer?to?B command is EL=eee
Maybe you can find other differences, but only these were interesting for me
when I wrote my software for rotators control -

Hi,
Would someone please be so kind as to explain the precise difference
between the two protocols GS232A and GS232B?
I am missing something obvious I expect but..
If you get an answer direct, would you please send it me also?

Hello Rocky,
Apology accepted.
Well, you are indeed fully entitled to your opinion, but I would submit 
that until you walk in the shoes of the ARRISat team members who are 
busting their pick to try and do the right thing for the members, maybe, 
just maybe, you should temper your judgment about their abilities and 
short comings given that without their very best intentioned efforts 
you'd have nothing to complain about and Amateurs wouldn't have a new 
satellite to look forward to. If our best efforts are not considered to 
be good enough by a few, we are encouraged by the many out there, who 
still cheer us on. And since those cheering far out number our 
detractors, then Robert, the ARRISat team is moving full speed ahead 
without you on our side.
Yes, you have assumed correctly, that it is our plan to proceed to the 
deployment date with confidence.
Regards...Bill - N6GHz
