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 contained in this bulletin item.] /EX SB SAT @ AMSAT $ANS-078.02 ITAMSAT-OSCAR-26 PROBLEM HR AMSAT NEWS SERVICE BULLETIN 078.02 FROM AMSAT HQ SILVER SPRING, MD MARCH 19, 1994 TO ALL RADIO AMATEURS BT BID: $ANS-078.02 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. 73 de ITAMSAT (IO-26) Command Team /EX SB SAT @ AMSAT $ANS-078.03 AO-13 OPERATIONS NET SCHEDS HR AMSAT NEWS SERVICE BULLETIN 078.03 FROM AMSAT HQ SILVER SPRING, MD MARCH 19, 1994 TO ALL RADIO AMATEURS BT BID: $ANS-078.03 Current AMSAT Operations Net Schedule For AO-13 AMSAT Operations Nets are planned for the following times. Mode-B Nets are conducted on AO-13 on a downlink frequency of 145.950 MHz. If, at the start of the OPS Net, the frequency of 145.950 MHz is being used for a QSO, OPS Net enthusiasts are asked to move to the alternate frequency of 145.955 MHz.

To: info-hams@ucsd.edu There are quite a few hams at NASA/Ames. They do have an active club with a pretty decent antenna farm.

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. --- Andy / VE1COR Andrew Cornwall Nova Scotia Department of Education Nova Scotia, Canada ------------------------------ Date: 21 Mar 94 08:18:28 GMT From: agate!howland.reston.ans.net!newsserver.jvnc.net!tiger!sun330.snu.ac.kr!usenet@ucbvax.berkeley.edu Subject: Difference between cordless phone and cellular phone?

To: info-hams@ucsd.edu 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.... 73's de Alex, ve2cnd@CAM.ORG ------------------------------ Date: 21 Mar 94 02:19:09 GMT From: news-mail-gateway@ucsd.edu Subject: help To: info-hams@ucsd.edu help ------------------------------ Date: 20 Mar 1994 18:38:09 GMT From: ihnp4.ucsd.edu!usc!howland.reston.ans.net!noc.near.net!news.delphi.com!gilbaronw0mn@network.ucsd.edu Subject: Long directories To: info-hams@ucsd.edu wy1z@netcom.com Scott Has again posted the LONG ftp directory.
