It is published every week and is made available for unlimited distribution. * DOVE STATUS * =============== Jim White, WD0E, reports that DOVE's voice synthesizer is undergoing tests. The satellite is now speaking the phrase "HI, this is DOVE in space" for one minute of every four minutes. "HI" has been traditionally sent from Amateur satellites since OSCAR 1, so it seemed appropriate for this re-activation of the voice synthesizer in DO-17. The team will continue to work on improvements, including possibly raising the amplitude of the voice, which is presently about half that of the telemetry. Software was completely reloaded last week. The S-band beacon has been turned off. Transmitter power will be optimized while maintaining a positive power budget. Reception reports are welcome (to PY2BJO). Telemetry is not needed. Jim White WD0E for the team: WJ9F, VK7ZBX, N5AHD, NK6K With support from WB6LLO and K0RZ * LUSAT STATUS * ================ LUSAT-OSCAR-19 is still not available for general use, and the BBS is not expected to be operational for the next few weeks. Raw telemetry should be sent by packet radio to LU8DYF@LU8DYF.BA.ARG.SOAM or LU8DYF@ANY-ACTIVE- SATELLITE, or via the Internet to: lu8dyf@asarin.org.ar. Certificates are available for those who forward telemetry reports. The LUSAT-1 recovery team wants to thank all stations who sent LUSAT-1 telemetry data in RAW format, including: JN2LHU, OZ6BL, OZ7SAT, EA1BCU, EA2CLS, WH6I, W9ODI, SM5BVF, ZS6BMN, JJ1WTK, LU1FYZ, LU2FCY, LU2JCI, LU1JBR, LU8ENU, LU6DYD and LU1DBC. [Info via Eduardo Sweet, LU7AKC (LUSAT-1 recovery team)] * ITAMSAT (IO-26) BACK ON * =========================== After a couple of weeks of stand-by mode, ITAMSAT under ground command was switched back ON. A new MBL code was successfully loaded to test the modified s/c configuration (secondary TX on). Telemetry shows all the vital parameters in nominal status. Further tests will be carried out in the next few days. Also due to the very limited time budget of the command stations, please expect a few weeks before normal operations. [Info via Alberto, I2KBD, of the ITAMSAT Command Team] * APT STATUS * ============== Observed at 50.7 NLat, 7.1 ELon (Germany) on 28-May-94: NOAA-9: APT 137.62 MHz On NOAA-10: APT 137.50 MHz *OFF* NOAA-11: APT 137.62 MHz On NOAA-12: APT 137.50 MHz On Meteor 2-21: APT 137.85 MHz On Meteor 3-5: APT 137.85 MHz *OFF* The VHF-conflict between NOAA-10 and NOAA-12 continues with NOAA-10's APT turned off. Meteor 3-5 APT is off too. The APT-frequency of Meteor 2-21 changed from 137.40 MHz to 137.85 MHz, but the signal is weak as always. As Meteor 3-5 is off, old NOAA-9 now is the best source for good vis-images. [Info via Peter Henne] * FO-20 NEWS * ============== On 19-May-94, the FO-20 command station announced that a problem exists in FO-20's onboard computer system. The satellite's transponder will remain in the analog mode (JA) until further notice. [Info via Kazu Sakamoto, JJ1WTK] * DISTRIBUTION INFORMATION * ============================ Recent FCC rule changes have made both the originator of packet radio bulletins as well as the control operator of the originating BBS legally responsible for the content of packet radio bulletins. As a result, many bulletins entering the Amateur Packet Radio Network (AMPR) must be held for review by the BBS sysop before forwarding can begin. The adoption of this new procedure will lead to delays in the distribution of SpaceNews and other bulletins within the Amateur Packet Radio Network. In addition, recent routing changes have lead to local Internet mail problems. This is expected to produce distribution delays within the packet network since the Internet is used as a SpaceNews distribution backbone. * THANKS! * =========== Thanks to all those who sent messages of appreciation to SpaceNews, especially: KB3AMR KB3MF VK4ZDR ...and Flavio Cimardi at IBM Microelectronics in Italy. * FEEDBACK/INPUT WELCOMED * =========================== Mail to SpaceNews should be directed to the editor (John, KD2BD) via any of the following paths: FAX : 1-908-747-7107 PACKET : KD2BD @ N2KZH.NJ.USA.NA INTERNET : kd2bd@amsat.org -or- magliaco@pilot.njin.net MAIL : John A.

This car has alot of computer controlled systems and I don't want to interfere with them. Also, although I haven't really spent a whole lot of time looking, I don't seem to be able to find anyway of running the power cables through the firewall. Will I have to drill a hole and put in my own grommet? I plan to put the antenna on the trunk. Any suggestions on the best path to run the feedline through?

Pick up this months CQ magazine (June) for a good explanation of PRB-1 and its effects on antenna legality. Overall, PRB-1 was a letter from the FCC that explained their policy that local communities really "should" help hams by "reasonably" accomodating towers and stuff. It had no teeth, and not surprisingly, has not fared well under the Federal Courts where it has been tested. 73 Clark WA3JPG ------------------------------ Date: 13 Jun 1994 21:07:17 GMT From: ihnp4.ucsd.edu!dog.ee.lbl.gov!agate!kabuki.EECS.Berkeley.EDU!kennish@network.ucsd.edu Subject: Nickel Hydride Cells To: info-hams@ucsd.edu In article <1994Jun13.083636.5538@ee.surrey.ac.uk>, Mike Willis wrote: >I have just bought 6 Nickel Hydryde AA cells for use with my Icom >handheld.

You can fast charge them -- in fact, they are designed to be fast charged, but charge control is critical if you decide to fast charge them. 2) Charging them at 70 mA is OK; it will just take a long time. The cells will take 100 hours of overcharge at 120 mA, so 70 mA is a very safe rate. 3) Anything greater than 360 mA is considered fast charge, which requires some method of detecting fully charged cells. At 240 mA, it is probably safe to just charge them for 7 hours, the overcharge not being that severe. At 360 mA, I wouldn't leave them for 5 hours unattended, as if the cells are not that discharged, you will have quite a lot of overcharge. You should monitor cell temperature or use the delta V technique, though it is much more difficult to do with NiMH cells than NiCd. Only at 1.2A charge do you see any sort of voltage drop -- you need to look for zero derivative of terminal voltage to do things right. 4) NiMH cells can withstand 3C discharge rates or 3.6 A. However, the cell temperature can rise and the heat can damage the batteries. But in an HT application, I don't think it is a problem. 5) NiMH cells have a very poor shelf life, especially at higher than room temperature. In 2 weeks at 40C, they are totally discharged. Good luck. -Ken ------------------------------ Date: 13 Jun 94 18:00:19 GMT From: ihnp4.ucsd.edu!library.ucla.edu!csulb.edu!paris.ics.uci.edu!news.claremont.edu!bridge2!Thoth!peter@network.ucsd.edu Subject: VHF Maritime Outrage!!
