- AO-13 ZRO TESTS RETURN!

- ZRO Tests Return To AO-13
-
- The ZRO Memorial Technical Achievement Award Program, or just "ZRO Test"
- has a new schedule for September and October '93 via AMSAT-OSCAR-13. This
- activity is a test of operating skill and equipment performance. Due to
- scheduling difficulties only three tests have been set up for this round
- so be sure to mark the test dates and times on your calendar.
-
- During a typical ZRO run, a control station will send numeric code groups
- using CW at 10 words-per-minute. At the beginning of the run, uplink power
- from the control station is set to match the general beacon downlink stren-
- gth. This is level "zero." The control operator will send and repeat a
- random five-digit number, then lower his uplink power by 3 dB (half power)
- and repeat the procedure with a new random number. This will continue to a
- level 30 dB below the beacon (level "A").
-
- A participating listener monitors the downlink signals until he can no long-
- er copy the numbers. Those who can hear the beacon will qualify for the
- basic award by copying the code group heard at level "zero". The challenge
- is to improve home-station performance to a point where the lower-level
- downlink signals can be copied (levels 6 through 9).
-
- The following schedule of Mode "B" tests were chosen for convenient oper-
- ating times and favorable squint angles. The tests can be heard on 145.840
- MHz. Andy (WA5ZIB) will conduct all the tests. Mode "JL" tests will no
- longer occur due to the failure of AO-13's 70-cm transmitter. Ed (N5EM)
- will be back next year after he completes station calibrations necessary
- to insure accurate Mode "B" activity. His "JL" tests were greatly apprec-
- iated.
-
- Sunday Sep. 26, 1993 at 0545 UTC
- Saturday Oct. 2, 1993 at 1335 UTC
- Monday Oct. 18, 1993 at 0430 UTC
-
- Note that the dates and days are shown in "UTC", thus the first and third
- tests shown occur in the late evening hours for those in North America.
- For example, the October 18th UTC test is at 11:30 PM CDT Sunday night (the
- 17th). Any
- changes will be announced as soon as possible via the AMSAT HF and AO-13
- Operations Nets.
-
- ZRO brochures are available from WA5ZIB, Andy MacAllister, AMSAT VP of User
- Operations, 14714 Knightsway Drive, Houston, TX 77083 for an S.A.S.E. with
- two units of postage. The brochure characterizes test procedures, means for
- obtaining certificates and gives some historical background about the prog-
- ram. New brochures were not made for the current round of tests, but this
- announcement and a graphical presentation of the satellite's view during
- the tests will be provided along with the March 1993 version of the
- brochure.
-
- All listener reports with date of test and numbers copied should be sent to
- WA5ZIB at the address above. A report will be returned verifying the level
- of accurate reception.

- 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.

-
- Any stations with information on current events would be most welcomed.
- Also, those interested in discussing technical issues or who have questions
- about any particular aspect of OSCAR statellite operations, are encouraged
- to join the OPS Nets. In the unlikely event that either the Net Control
- Station (NCS) or the alternate do not call on frequency, any participant is
- invited to act as the NCS.

- Mode-B : MA 0 to MA 60 !
- Mode-BS : MA 60 to MA 120 !<- after Aug 30 (hopefully)

- Continuous up-to-date information about AO-13 operations is always available on
- the
- beacons at 145.812 MHz and 2400.646 MHz in CW, RTTY and 400 bps PSK. Also,
- these
- bulletins are also posted to INTERNET, ANS bulletins, Packet, PACSATs, etc.,
- and can also
- be found in many international newsletters. [G3RUH/DB2OS/VK5AGR]
-
- AO-16: Operating normally. SATGATE operations have moved from LO-19 (LUSAT)
- to AO-16 (PACSAT). As KI6QE indicated when the move was made, the number
- of files involved is quite small, so it is still possible to keep track of
- everything on this satellite even with checking a few times a week. [WH6I]
-
- UO-22: Operating normally. There were a few good images last week. [WH6I]
-
- KO-23: Operating normally. [WH6I]
-
- FO-20: N0NBH reports that FO-20 continues to operate normally after last
- week's on-board computer resets. [N0NBH]
-
- UNAMSAT-1: The Mexican MICROSAT is scheduled for launch late this year on a
- refurbished Soviet ICBM designed to carry satellites. So far Program Man-
- ager XE1TU does not have all the final keplerian elements of the intended
- orbit. However, the known parameters are as follows:
- Orbital Inclination = 73 degrees
- Altitude = 730 KM
- Orbital Eccentricity = 0.00000000
- The satellite will separate from the rocket with no spin. All transmitters
- will be silent at separation and for a period of at least 1 hour. The VHF
- receive antenna and the two halves of the canted dipole for 40.997 MHz will
- be collapsed and then they will be deployed 3 minutes after separation.
- [XE1TU]
-
- RS-10: HB9RHV is quite active on RS-10 and looks forward to contacts and
- schedules for those who would like to make a DX contact. [HB9RHV]
-
- UO-11: Controllers at the UoSAT Control Centre at the University of Surrey
- are requesting the help of the amateur radio community around the world in
- collecting information and data from UOSAT-OSCAR-11. The Forth Diary Oper-
- ating system aboard UO-11 has crashed within the past 24 hours. This has
- rendered the spacecraft in a non-nominal operating state. The collection of
- information and data related to the operational condition of the spacecraft
- over the next several days will be essential in helping the controllers to
- understand the spacecraft's current condition. Therefore the UoSAT command
- team is asking radio amateurs around the world to monitor the spacecraft and
- relay any reception reports and or telemetry data collected from the space-
- craft to them via G0SYX @ UO-22, G0SYX @ KO-23 or via the INTERNET address:
- D.Loughmiller@ee.surrey.ac.uk UOSAT-OSCAR-11 operates on a 2M frequency of
- 145.825 MHz and on a 70 cm frequency of 435.027 Mhz. Controllers are most
- interested in which beacon is active at the time of any given observation
- and whether the signal contains data or not. Any telemetry data collected
- would be of particular interest to the controllers as well. Any observ-
- ations provided by the amateur community will be most appreciated. UoSAT
- controllers will issue subsequent bulletins about the status of the
- UoSAT-OSCAR-11 spacecraft as the situation develops. [KO5I/G0SYX]
-
- The AMSAT NEWS Service (ANS) is looking for volunteers to contribute weekly
- OSCAR status reports. If you have a favorite OSCAR which you work on a
- regular basis and would like to contribute to this bulletin, please send
- your observations to WD0HHU at his CompuServe address of 70524,2272, on
- INTERNET at wd0hhu@amsat.org, or to his local packet BBS in the Denver, CO
- area, WD0HHU @ W0LJF.#NECO.CO.USA.NOAM. Also, if you find that the current
- set of orbital elements are not generating the correct AOS/LOS times at
- your QTH, PLEASE INCLUDE THAT INFORMATION AS WELL. The information you
- provide will be of value to all OSCAR enthusiasts.
