Sion,
I don't own a G-5500, but I do have both a G-5400 and G-800. The G-5400
and G-5500 are similar (not identical) judging from the manuals.
>From looking at the manual for the G-5500, the azimuth rotor is completely
different from the G-800. The G-5500 (and the G-5400) azimuth rotor is an
AC motor with two coils and three wires for the motor. The G-800 is a DC
motor with only two wires. (Both systems use an additional 3 wires for
the position potentiometer, so five wires for the G-800 and six wires for
the G-5400/G-5500.)
The G-450A rotor is similar to the azimuth half of the G-5500, judging
from the manual. However, I'd look for someone who owns a G-450A who can
verify that for you. The G-450A manual omits a schematic and some
important specifications like the motor voltage. You may also be able to
get some help from Yaesu customer service.

Phil, Thank You very much for your excellent effort to digitize and keep
AMSAT Publications. I have been active with AMSAT since the early
1970 and do have some some publications. I will inventory my collection and
if they are not on your fine list I will send you dates and see if you can
use them. I noticed the references in the newsletters to the AMSAT
International Net on 14,280mhz and the North American 75 Meter nets on 3.855
mh what fun I can still remember coping the AMSAT Bulletins on paper......

You're welcome! I think my collection of the early stuff is pretty
complete but if you (or anyone) have anything that's missing I'd love to
add it.

The AMSAT International Net still holds forth on Sunday at 1900 UTC
now on 14.282 MHz. The pre-net warm up session begins shortly after
1800 UTC with informal contacts and questions and answers.

Well,
If I am not mistaken, the copyright is still with AMSAT. Certainly would be
nice to get permission from the AMSAT office before the electronic

Dear All,
Thank you for all the replies to this topic which is greatly appreciated.
In conclusion, I guess I will have to either (1) Replace the azimuth portion
with a G-800 using a seperate control box for azimuth and elevation or (2)
try to replace the azimuth portion with a G-450 rotor.
Has anyone successfully tried connecting the G-450 rotor motor directly to
the G-5500 control box?

Greetings AMSAT!
I am one of the software engineers on the CAPE-2 Cubesat project at
the University of Louisiana at Lafayette. I am interested in
information on how to set up our satellite to tweet over APRS to a
specific twitter account.
For example:
If i want our satellite to tweet once a day what our satellite's
status is, and have it be posted to a CAPE-2 twitter account, how can
i make this happen? We've seen other groups do it, and we are
wondering how to replicate this.
Thanks for your help!

Hi Rizwan,
First of all: we are all very interested in your CAPE-2 project.
Would you be able to share some more information on CAPE-2 ?
In case you involve radio-amateurs in capturing telemetry/data from your
satellite you will have an huge increase in coverage, as we are spread
across the entire globe. We do have the APRS system up-and-running, and
NO-44 (PCSAT-1) and ISS-APRS data packets for example are monitored and
automatically forwarded to the internet already.
On messaging to twitter email:
In case of a malfunction or wrong software setting the satellite may not be
able to change its transmission pattern, when it is in space and cannot be
reached anymore (e.g. up-link broken). Alternative would be to break it up
in two steps:
Step 1
Transmit a status in APRS format, and have that captured/received as regular
packets. Here is for example how all the ISS data (real-time) looks like:
http://www.ariss.net, and here is how NO-44 looks like:
http://www.findu.com/cgi-bin/pcsat.cgi
Step 2
Have a software program running that looks at the the received APRS
telemetry, and derive from that a Twitter tweet (every hour, every day,
...). For example if the telemetry says: "CAPE 012000105" this could mean I
am alive and battery voltage is 10.5 volt and temperature is 12 degrees
Celsius. The tweet could be: "Hi this is CAPE-2 in space, I feel cold (12C)
and my battery is good (10.5V)".
Just a thought.
Regarding APRS email: http://www.aprs.org/aprs-messaging.html explains how
to do this.
Here is an example on how this worked on ANDE-1:
ANDE-1 digipeat:
!T 12:26:38 PA3GUO-8>APRS,ANDE-1*,qAO,PE1ITR::email :pe1itr@xxxxxxx.xxx

Hi Henk,
CAPE-2 is the second satellite from the Cajun Advanced Picosatellite
Experiment. We are planning to fly a digipeater, text to speech
module, voice repeater and VHF and UHF radios. I am currently
developing software to distribute to you guys later this year that
will copy our telemetry and have it automatically sent back to us.
We have already implemented the ability to send APRS emails, but would
now like to do the same with twitter.
Sincerely,
Rizwan Merchant

> In case you involve radio-amateurs in capturing telemetry/data from your
satellite you will have an huge increase in coverage, as we are spread
across the entire globe. We do have the APRS system up-and-running, and
NO-44 (PCSAT-1) and ISS-APRS data packets for example are monitored and
automatically forwarded to the internet already.

telemetry, and derive from that a Twitter tweet (every hour, every day,

am alive and battery voltage is 10.5 volt and temperature is 12 degrees
Celsius. The tweet could be: "Hi this is CAPE-2 in space, I feel cold (12C)
and my battery is good (10.5V)".

It seems that Gmail deleted the subject line. It read:
"Possible Cause Of Proton Crash Found"
