I rigged something that works pretty well from a few more bits of PVC, a
couple L brackets and a hose clamp. I can take a few snaps with my phone and
send them to you directly if you like.

2009 AMSAT Field Day Rules
AMSAT News Service Bulletin 132.02
From AMSAT HQ SILVER SPRING, MD.
May 3, 2009
To All RADIO AMATEURS
BID: $ANS-132.02
The AMSAT Field Day 2009 event is open to all Amateur Radio operators.
Amateurs
are to use the exchange as specified in ARRL rules for Field Day. The AMSAT
competition is to encourage the use of all amateur satellites, both analog and
digital. Note that no points will be credited for any contacts beyond the ONE
allowed via each single-channel FM satellite. Operators are encouraged not to
make any extra contacts via theses satellites (Ex: AO-27 & SO-50).
CW contacts and digital contacts are worth three points as outlined below.
1. Analog Transponders
ARRL rules apply, except:
- Each phone, CW, and digital segment ON EACH SATELLITE TRANSPONDER is
considered to be a separate band.
- CW and digital (RTTY, PSK-31, etc.) contacts count THREE points each.
- Stations are limited to one (1) completed QSO on any single channel FM
satellite. If AO-51 has the V/U and L/S modes turned on, one contact each
is allowed. If the PBBS is on - see Pacsats below, ISS (1 phone and 1
digital), Contacts with the ISS crew will
count for one contact if they are
active. PCSat (I, II, etc.) (1 digital),
- The use of more than one transmitter at the same time on a single
satellite transponder is prohibited.
2. Digital Transponders
For the Pacsats (GO-32, AO-51) or ?Store and
Forward? hamsats, each satellite is
considered a separate band. Do not post "CQ" messages. Simply upload ONE
greeting message to each satellite and download as many greeting messages as
possible from each satellite. The subject of the uploaded file should be
posted
as Field Day Greetings, addressed to ALL. The purpose of this portion of the
competition is to demonstrate digital satellite communications to other Field
Day participants and observers. Do not reply to the Field Day Greetings
addressed to ALL.
The following uploads and downloads count as three-point digital contacts.
(a) Upload of a satellite Field Day Greetings file (one per satellite).
(b) Download of Satellite Field Day Greetings files posted by other stations.
Downloads of non- Field Day files or messages not
addressed to ALL are not to be
counted for the event. Save DIR listings and message files for later "proof of
contact."
Please note AMSAT uploaded messages do not count for QSO points under the ARRL
rules.
Satellite digipeat QSO's and APRS short-message contacts are worth three
points
each, but must be complete verified two-way exchanges. Remember, only one
digipeat contact is allowed for the ISS and other satellites in this mode.
The use of terrestrial gateway stations or internet gateways (i.e. EchoLink,
IRLP, etc.) to uplink/downlink is not allowed.
3. Operating Class
Stations operating portable and using emergency power (as per ARRL Field Day
rules) are in a separate operating class from those at home connected to
commercial power. On the report form simply check off Emergency or Commercial
for the Power Source and be sure to specify your ARRL operating class (2A, 1C,
etc.).
AND FINALLY...
The Satellite Summary Sheet should be used for
submission of the AMSAT Field Day
competition and be received by KK5DO (email or postal mail) by 11:59 P.M. CDT,
Monday, July 13, 2009. The preferred method for submitting your log is via
e-mail to kk5do@xxxxx.xxx or kk5do@xxxx.xxx.
You may also use the postal service but give plenty of time for your results
to
arrive by the submission date. Add photographs or other interesting
information
so that can be used an article for the Journal.
You will receive an email back (within one or two days) from me when I receive
your email submission. If you do not receive a
confirmation message, then I have
not received your submission. Try sending it again or send it to my other
email
address.
If mailing your submission, the address is:

Hello group,
I have a 6 year old G-5500 rotor on my portable SAT setup and upon
setting it up tonight, I found that the EL rotor has ceased to work. AZ
works fine. Checked the screw-on connector, checked the controller, etc.
The rotor makes a clicking sound when the control is engaged, and a
humming noise until released. At least the rotor is mounted only 6 feet
off the ground, hi,hi. Any ideas before major surgery would be appreciated.
TIA

Hi Fellow Amateurs,
Cal Poly's next satellite, CP6, is scheduled to launch on May 5th between
20:00 and 23:00 EDT. We would be more than happy if everyone who is
interested could listen for CP6 as it comes over your locales. We will be
providing a CPX Data Decoder program which will show you all of your decoded
data as well as forward those packets to us at Cal Poly. I will be sending
out another email in a few days regarding how to download the program.
Also to note, we will be in the IRC chatroom at 'irc.freenode.org' in the
'cubesat' room before, during, and after the launch. Thanks!

I sure hope they have a true FSK demodulator, because trying to match almost
9000 Hz of Doppler in the blind to within 100 Hz or so to use AFSK for
something that only lasts a second will be a real challenge....
But it is good to see something new in space!

Hi Bob,
I second your comments. Waiting 2 minutes for a 1 second burst is going
to be a challenge indeed, even with computer controlled receiver tracking.
Jason, I trust you have the transmit sequence correct?? What's the
planned Pout? What's the best link to tech details?
But we can always use a new challenge so the very best of luck to your team.

All,
yes it is a real challenge - but I heard many beacons from CP4 long time ago
(sometimes in 5-minutes interval !)
The most important thing is to listen to CW header (6 seconds) - in this
time you can adjust the frequency and catch the packet burst. I hope it's
the same like CP4....
A running spectrum analyzer software is very helpful. So you can quickly
adjust the frequency to the right value.
Some older CP4 reports on my website
http://www.dk3wn.info/sat/afu/sat_cp.shtml
It's in German but I think you can understand the way I went.
Another way is to record the beacon and then analyze the burst with MixW.
There is an CUSTOM AFSK mode.
Keep my fingers crossed and best 73,
Mike

Shawn,
You can swap the connectors at the motors. They are electrically identical,
though of course the meters will not read correctly. If the problem follows
the connectors, then it is something in the control box, cables, or
connectors. If not, the motors.
One thing you can check at the shack end is the 3 wires to the motors.
Lines 4, 5, and 6 should all have continuity, with a few ohms showing.
"Few" being something like 5 ohms. I can't find my notes with the exact
numbers, and they will depend on the length and type of the lines.
If everything checks, then it is _probably_ the 100 uF phase shift capacitor
you can see between the windings in the schematic. You can get a
replacement from Yaesu for $10-15 including shipping. Replacing it is not
hard, but it is very tedious and messy. Unlike other versions, the G-5500
has the capacitor in the motor housing rather than the control box.
I had exactly the same symptoms you describe, and it was the capacitor in my
case.
Good luck,

Hi Alan and Shawn,
FYI about a month ago I attempted to get that cap from Yaesu and they
said they
no longer sell it by itself, you either buy it with the motor or find a
3rd party
replacement.

Disappointing, but not unexpected of Yaesu. If they are selling just the
motor, considering the time and tools necessary to crack open the case, it
might really be cost effective for most people.
>From this and other references, it seems there have been a lot of failures
of those capacitors lately. There are good electrical reasons to put the
capacitor in the motor, but environmentally, especially with hot summers,
they take a beating.

Hello group,
Well, looks like I have to crack open the case. I swapped the AZ and
EL cables with the EL rotor, and no luck, same result. Still making the
click noise when engaging the UP control, the motor(?) still hums away
(sounds like 60 Hz), but no movement. Last resort now , open it up and
hope to catch all the bearings, hi. Since it seems Yaesu wont sell the
capacitor sans motor, are there any know sources, or just look at
Allied, Mouser etc.?
Thanks for the help -
Shawn N1HOQ.

HI all,
Small motor capacitors can be found 2 Grainger, and McMaster Carr. These
are run capacitors and are rated for continuous duty.
Art,

Alan & Shawn - my elevation rotor went bad as well a few months ago.
However it wasn't the capacitor; I sent Shawn off list the email of
the person who repaired the motor for me.
Now as far as the cap, if the 5500 is similar to my 5400, the cap is
easily removed without having to crack open the housing. There's an
aluminum plate on the side with 4 small screws. Remove those screws
and the plate, and you will see the cap inside. If you are careful,
and take your time, you can remove it and replace it.
