PHASE-3D STATUS REPORT
HR AMSAT NEWS SERVICE BULLETIN 078.01 FROM AMSAT HQ
SILVER SPRING, MD MARCH 19, 1994
TO ALL RADIO AMATEURS BT
BID: $ANS-078.01
AMSAT PHASE 3-D INTERNATIONAL SATELLITE BUILDERS MEET IN
MARBURG--PROPELLANT TANKS DELIVERED
During the week of February 10-16, 1994, Dr. Karl Meinzer, DJ4ZC,
AMSAT-DL President and Project Leader for the International AMSAT Phase-3D
satellite, and Werner Haas, DJ5KQ, Vice-President of AMSAT-DL hosted
a working meeting in Marburg, Germany to discuss recent progress on the
project. Agenda items centered primarily around the spacecraft's
electronic systems including the on-board computer (IHU) and RUDAK
systems, as well as the progress now being made by team members on the
spacecraft's other electronic modules.
Also during the meeting, the team took delivery of P3-D's main
propellant tanks. The tanks were manufactured in Russia under contract
from AMSAT-DL and in accordance with AMSAT specifications. Seven tanks
were delivered, although one had been subjected to a destructive pressure
test by its Russian manufacturer.
Not only have all the propellant tank specifications been fully
achieved, but they've actually been significantly surpassed. Each tank
can accommodate almost 50 liters of propellant. Favorable conditions for
the purchase and delivery of these tanks was arranged through the efforts
of AMSAT-UA (Russia). Following a brief inspection, the tanks were
immediately shipped to Orlando, Florida, where integration of the
satellite is now slated to begin this summer.
Dick Jansson, WD4FAB, AMSAT-NA Vice-President for Engineering, also
attended the meeting, principally to discuss various aspects of the
satellite's structure with Dr. Meinzer and Konrad Mueller, DG7FDQ. He
reported on the good progress of the flight model structure's construc-
tion, currently underway at Weber State University in Utah.
Also in attendance were Lyle Johnson, WA7GXD, Peter Guelzow, DB2OS, and
Gerhard Metz, DG2CV. Lyle is known through his work with the Tucson
Amateur Packet Radio (TAPR) group (which he co-founded) as well as for
his work on the Microsats and on the P3-D GPS project. After much
discussion, the team decided to again employ a cable wiring harness
arrangement for Phase 3-D, similar to that used on AO-10 and AO-13,
rather than an AART-based LAN design. However, the team decided to also
fly a CAN bus and DB2OS's experimental LAN controller as part of the
spacecraft's digital (RUDAK) transponder.
In a related decision, the group concluded that the AO-10/AO-13
1802-based Internal Housekeeping Unit (IHU) computer design would still
be adequate for P3-D with some minor modifications. Lyle Johnson
announced his willingness to redesign the IHU and to construct a flight
unit. His offer was greatfully accepted.
Other meeting items centered on P3-D's RUDAK work now being done by
Peter Guelzow, Gerhard Metz, and Dr. Stefan Eckart, DL2MDL. This team
has now decided to build two RUDAKs. The first will be a user-oriented
digital communications module constructed by Lyle Johnson, in close
cooperation with Peter Guelzow. This RUDAK, which has yet to be formally
named, will be the one most P3-D satellite users will operate. A second,
more experimental RUDAK (called RUDAK-E), will be built in Germany. It
will promote experiments with advanced high speed modems, Digital Signal
Processing (DSP) techniques, and new communications protocols.
In a host of other issues, Daniel Orban, ON4AOD, discussed details
of the 24 GHz transmitter. Konrad Hupfer, DJ1EE, reported his progress
in building the 250 watt U-Band (70 cm) final amplifier. Werner Haas
displayed his first flight hardware consisting of two command receivers,
a digital section, and the 70 cm exciter that will drive Konrad's 70 cm
final amplifier. Freddy de Guchteneirie, ON6UG, reported his progress on
the construction of dual V-Band and U-Band receiver "front-ends". Dr.
Matjaz Vidmar, S51MV, reported he has now begun construction of the
HF-Band, C-Band and S-Band receivers. He expects to deliver working
prototypes in May.
While much work still remains to be done, Dr. Meinzer expressed his
approval and sincere thanks to all participants for their superb work and
close cooperation on this vitally important AMSAT international project.
A complete text of this meeting's minutes has been prepared by Peter
Guelzow, and has since been translated by Don Moe, DJ0HC/KE6MN. The text
will be made available to the various international AMSAT Journals for
possible inclusion in their upcoming editions.
[The AMSAT News Service (ANS) would like to thank Peter Guelzow, DB2OS, Don
Moe, DJ0HC/KE6MN, Lyle Johnson, WA7GXD, and Keith Baker, KB1SF, for their
assistance in writing, translating, and formatting the information

ITAMSAT-OSCAR-26 (IO-26) Ground Team Discovers Problem
Starting last week the PSK modulation on the primary trasmitter became more
and more difficult to decode. A residual carrier and lower output power
seem to indicate a failure in the PSK balanced modulator, being worse at
the current low power setting. Increasing the power level makes the de-
modulation better but is not accetable due to power budget constraints.
Ground controllers decided to switch to the secondary PSK trasmitter on
435.822 MHz. The first two passes over Italy confirmed the correct
operation of the spacecraft and WOD are being taken to analize the per-
formance of the satellite in this new configuration. BBS is working as
usual and status bulletin will be uploaded in the next few days.

Subject: BAYCOM <-> NOS, YES!
To: info-hams@ucsd.edu
About 2 weeks ago I launched the following inquiry on Info-
Hams Digest:
>Hello. If you have been able to use a Baycom (Baypac) type
>modem with KA9Q/NOS (for example NOS 1.10x15) I would like
>to know how it is done...
I received several responses and am pleased to report that I
have succeeded in getting NOS to work with the Baycom modem. What
I needed was an ax25 driver program (ax256drv.zip of January 3,
1993 downloaded from grivel.une.edu.au / 129.180.4.7) written by
Pawel Jalocha, SP9VRC. The only glitch encountered was resolved
by a simple change of driver software interrupt from the default
of 60 to 63 to work with my i386SX laptop.
After more than a week's experience, I am finding that the
Baycom (with ax25 driver) works as well as my MFJ 1278 and
PacComm TNCs for 1200 bps. It is connected to a Yaesu FT-470
handheld through a 25 watt amplifier to a simple j-pole antenna.
(For regular packet operation I have had no difficulty using the
Baycom with the laptop running the Eskay SP and MUBAY software,
but I am not able to make the modem work with the Baypac program
that was bundled with it.)
The reports from other hams were generally very positive
regarding use of the Baycom modem with NOS, although there was an
instance of heavy packet loss noted in conjunction with an HTX-
202 HT. Another ham expressed particular satisfaction with the
Yaesu FT-470, which duplicates my experience.
I am grateful for the work of Pawel Jalocha in writing the
ax25 driver, and, of course, the work of KA9Q, WG7J and other
contributors for producing the NOS program.

Hello everybody....
The origin of the word 'HAM' come from the first letters of the
first three guys to experiment radio. They were from the Harvard Radio
Club... Their names are Hyman, Almy and Murray.
Originally, they named their telegraph station
"HYMAN-ALMY-MURRAY" but it was too long, so they reduce it to "HY-AL-MU",
but there was a problem : a mexican boat was named "HYALMO", so there was
a little confusion... So, they finally named their station "HAM"...
Oh yeah... That was in 1908....
