- AMSAT-IT & AMSAT-NA Sign "Memorandum-of-Understanding" On MICROSAT
-
- AMSAT-ITALY and AMSAT-NA signed a "Memorandum-of-Understanding" (MOU)
- agreement allowing for the co-construction of a MICROSAT/PACSAT
- satellite. This agreement allows for the joint construction of a
- MICROSAT satellite with AMSAT-NA sharing fully its technology and
- assisting AMSAT-IT in this endeavor. This represents the first time
- that AMSAT-IT has ever attempted to build an OSCAR satellite. By
- teaming with AMSAT-NA, AMSAT-IT will get to study, observe, and learn
- about on all aspects of building a OSCAR satellite from "bending metal"
- to integrating it upon a launch vehicle. Signing this "historic"
- agreement for AMSAT-IT was Dr. Alberto Zagni, I2KBD, who was also
- representing the ARI (Italian National Radio Institude); signing for
- AMSAT-NA was Jan King, W3GEY, Chairman of the Board. This MOU was
- signed in Boulder, CO on March 19, 1989. The new AMSAT-IT MICROSAT
- will be known as ITAMSAT-1 and is expected to be finished and launched
- within two years. The center for this effort in Italy will be in Milan
- with Dr. Zagni being designated as the the Program Manager for
- ITAMSAT-1. AMSAT-NA welcomes this "teaming agreement" with AMSAT-IT
- and looks forward to the successful launch of another OSCAR satellite.

- AMSAT-NA To Offer TAPR PSK Demodulator Boards
-
- OSCAR satellite enthusiasts will now be able to obtain TAPR PSK
- Demodulator kits from AMSAT-NA Headquarters thanks to a recent
- agreement reached with TAPR. This agreement was reached inorder to
- encourage amateurs to start building these kits now so that they will
- be ready for the PACSATs to be launched later this year. By becoming a
- "second-source" for these kits, TAPR is hopping to avoid a "last minute
- rush" by amateurs to become "operational" once the PACSATs are released
- for general use. For those who would like to learn more about this
- particular kit, see ASR #135 or the ARRL's QEX magazine, Sept. 1987.
- To order your PSK Demodulator board, call AMSAT Headquarters, at (301)
- 589-6062.

-
- MICROSAT Progress Report #2 By Jeff Zerr
-
- Jeff Zerr, AMSAT-NA's Engineer-in-Charge of MICROSAT Mechanical
- Assembly presents the following summary of progress to date on the
- MICROSATs:
-
- 1) MICROSAT assembly and construction site has been sucessfully moved
- to a new facility last week in order to allow for more room. The phone
- number at the new facility is (303) 530-7233. The new facility is
- located at 5305 Spine Road in Boulder, CO. Volunteers meet every
- Wednesday night at 7:00 P.M. and Sunday mornings at 9:00 A.M. Jeff
- reports that a "make-shift" clean room has been built and is in
- operation.
-
- 2) The MICROSAT Critical Design Review (CDR) was held the weekend of
- March 18-19th in Boulder, CO. The CDR is a process where by the
- complete satellite design is gone over in "excruciatingly painful"
- detail in order to uncover any hidden "gottcha's" which might pop-up
- later. Jeff reports that the CDR went very well and except for a few
- minor problems, they can be readily solved. [In a future AMSAT News
- Service Bulletin, a detailed summary will be given of this very
- important CDR activity.]
-
- 3) Prototype receivers designed by W3IWI and built by W4PUJ were
- demonstrated and "fit checked." The Battery Charge Regulator (BCR),
- designed by Jon Bloom, KE3D, was displayed and it too also was "fit
- checked."
-
- 4) YT3MV continues making excellent progress on his S Band transmitter
- which will now fly on one of the MICROSATs as an additional experiment.
- The reported efficiency of this transmitter is approximently 50 per
- cent.
-
- 5) Tom McIntire, KB0BGZ, continues to supply battery "cradle" modules.
- These specially designed "battery holders" are designed for the nicad
- batteries which will power the MICROSATs.
-
- 6) Hugh Pett, has finished writing the software for the "boot-loader"
- for the on-board V-40 CPUs on each of the MICROSATs.
-
- 7) Larry Kayser and Stan Kasmeric have now delievered all the 6.7
- Amp-hr, 1.5 volt, nicad batteries for all the MICROSATs. All have been
- tested and "conditioned" for space flight operation.
-
- 8) Bob Strickland has finished all the final revisions to his
- Addressable Asynchronus Receiver Transmitter (AART) boards and he will
- deliver them at the end of this month.
-
- 9) Don Struthers has a working model of the DOVE (Digital Orbiting
- Voice Encoder) voice synthesizer. He is now working putting his
- efforts in the software programming aspects of it now. Don is using
- the commercially available chip, called VORTRAX SC-02, as the center of
- this design.
-
- Jeff wants to remind everyone that the final integration and check out
- of the MICROSATs is planned for May 15, 1989! Volunteers are very much
- needed to help make this happen. You don't have to live in Boulder to
- become a MICROSAT volunteer. Jeff points out that many volunteers who
- are making major contributions to the construction effort live out-of-
- state. If you would like to volunteer to build something, Jeff will be
- happy to send you copies of the necessary drawings. Please volunteer
- today -- call Jeff Zerr at (303) 530-7233.

-
- Short Bursts
-
- All AMSAT-NA members should have received a letter recently from AMSAT
- President Doug Loughmiller, KO5I, seeking each members support during
- this crucial time. At no other time in AMSAT-NA's history has there
- been a period where AMSAT-NA has had four satellites under construction
- at one time! All members are urged to consider this important message
- which Doug has felt it is necessary for him to communicate to each and
- everyone of you at this time.
-
- The following is the operating schedule for FO-12 for April:
-
- DATE MODE OPERATING PERIOD
- 04/05/89 JA 14:12 UTC until 22:24 UTC
- 04/08/89 JA 21:45 UTC until 12:38 on 04/09/89 UTC
- 04/11/89 JA 12:51 UTC until 21:04 UTC
- 04/13/89 JD 13:05 UTC until 21:17 UTC
- 04/15/89 JD 19:30 UTC until 12:24 on 04/16/89 UTC
-
- Effective March 15, 1989 the Operating Schedule for AO-13 was changed
- as follows:
-
- Mode B From MA 100 to MA 160
- Mode JL From MA 160 to MA 200
- Mode B From MA 200 to MA 255
- OFF From MA 0 to MA 100
-
- The final Bahn Coordinates for AO-13 after the attitude change will be
- as follows: Bahn Longitude=210 degrees, Bahn Latitude=+5 degrees.
-
- Listen to the CW/PSK/RTTY telemetry beacons on AO-13 on a downlink
- frequency of 145.812 MHz/435.651 MHz and to AMSAT Nets for the latest
- information on any operating schedule changes. The above operating
- schedule will remain in effect until May 3, 1989.
-
- AMSAT members are reminded that there will be a switch to Daylight
- Savings Time on the first weekend of April. This time change only
- impacts the 75M Meter and local VHF Nets! It DOES NOT affect the Inter-
- national Nets on 20M and 15M -- they stay on UTC time. Please keep
- this in mind so you don't miss any of the many regularly scheduled
- AMSAT Nets.

- OPS NET NEWS:
-
- The AMSAT Operations Net of March 18,1989, was held as
- scheduled at 1600 UTC on a downlink frequency of 435.970
- MHz. With only 21 minutes of "JL" time available till
- Mode "B", the net was continued on 145.950 MHz after the
- switch. Conditions for the net were very good on both
- "B" and "JL". While most stations used the two-meter
- uplink of "JL", Keith, W5IU, checked in via the 23-cm
- uplink of the "L" transponder.
-
- Andy, WA5ZIB, was NCS. Check-ins included: VE7DOX, W6HDO,
- W7ID, W5IU, WB6LLO, K6TSK, WA4UPD, VK4ZQ and K4ZQX.
-
- The following topics came up during the net:
-
- 1. ZRO Test - The next ZRO runs will begin in May after the
- satellite is back to NADIR pointing. Results from the
- March 4th run have some European stations providing
- Z7 reports. The March 5th test has produced level 8
- reports from W7ID, and others "down-under" in Australia
- and New Zealand. "JL" tests will start in May or June.
-
- 2. 73 Magazine - The special satellite issue was mentioned.
- It will have 17 articles written by AMSAT supporters and
- Satellite enthusiasts from West Germany, England, New
- Zealand, South Africa and the U.S. "73" was overwhelmed
- with submissions and will have plenty of material to
- keep satellite articles of some type in every issue of
- the magazine through the end of the year.
-
- 3. Satfoxhunt - Although no discussion ensued, WA5ZIB
- mentioned the efforts of N5BF, WB5CCJ and W5SXD to
- prove the possibility of a satellite-based fox hunt.
-
- 4. A-O-10 - VK4ZQ, Roy in Brisbane, mentioned the FM'ing
- on the A-O-10 transponder. Users have been asked to
- QRT when heard in the downlink. Keith, W5IU, said that
- he had not heard anything from the satellite in the past
- few days. Although the bird is not yet in eclipse
- season, we must assume that the solar illumination has
- reached a critical level. A-O-10 is once again in
- hibernation.
-
- 5. Mystery beacons on "JL" - W6HDO asked if anyone had
- information on the Russian beacons heard on 435.947 MHz.
- They send CW and use the callsigns UZ9XXZ and UZ9VXZ.
- Are they on two-meter uplinks being transponded via 23
- cm? What are they for?
-
- 6. March 11th Net - Keith, W5IU and N8IWJ were active for
- nearly 45 minutes for the period of the March 11th net.
- Although spin modulation was very difficult due to bad
- squint angle, they persisted.
-
- 7. Next Net - The next AMSAT Operations Net is scheduled for
- March 26, 1989 at 0530 UTC. That's Saturday evening,
- local time. Come by and join us! If Courtney is
- available, he (N5BF) will act as NCS, otherwise WA5ZIB
- will do the honors.

- L
- de VK5AGR 04Mar89 1330utc Peter DB2OS - I hq6 looked at the
- squint angles resulting from the proposed attitude change of
- AO-13 to 210/+5 on 13Mar89 for stations located in the Northern
- and Southern Hemispheres. Squint `ngles of less than 20 degrees
- occur in the Northern Hemisphere between MA 160 and 230 and be-
- tween MA 135 and 200 in the Southern Hemisphere. Therefore, your
- choice of MA 160 to 200 means that stations in both Hemispheres
- will have at least 40 MA units of good Mode JL. 73s Graham

- de VK5AGE/G3RUH 89 Mar 26 1150utc. A third magnetorque for 2
- perigees (Orbits #596/597 & #597/598) refined the attitude to
- LON/LAT = 206/4 Another session will occur during the peri-
- gees of Orbits #598/599 & Orbits #599/600. This will result
- in an attitude close to the desired 210/+5 - We'll upload
- the final attitude to the CW/RTTY/PSK bulletins on 89 Mar 27.
