- ======================

- Headquarters, Washington, D.C. October 22, 1993
-
- MARS OBSERVER INVESTIGATION BOARD STATUS REPORT
-
- The Mars Observer Investigation Board held its third set of meetings,
- Wednesday through Friday, October 20-22, in Washington, D.C.
-
- Since the last set of board meetings, technical teams conducted reviews of
- specific Mars Observer subsystems at the Jet Propulsion Laboratory, Pasadena,
- California, and Martin Marietta Aerospace, East Windsor, New Jersey.
-
- Plausible scenarios for what could have caused the loss of communication
- with the Mars Observer spacecraft are still being developed and technically
- challenged.
-
- The board previously had recommended a program to attempt to activate the
- Balloon Relay Experiment, an instrument onboard Mars Observer. After several
- attempts to activate the experiment, ground station engineers did not detect
- any return signals. The NASA Deep Space Network stationed at Goldstone,
- California, and the Jodrell Bank Observatory, United Kingdom, were used.
- Non-activation of the Balloon Relay Experiment leads the board to conclude
- that a Mars Observer failure scenario involving only the spacecraft downlink
- portion of the telecommunications system is highly unlikely.
-
- In the coming weeks, the board will evaluate results of hardware and software
- tests, and in some cases, computer simulations of various spacecraft
- subsystems.
-
- Late November is still the target timeframe for delivering a final report
- to the NASA Administrator, who will make the report publicly available.

- This is STS-58 SAREX Robot station W5RRR-1
- onboard the Space Shuttle Columbia.

- * TEXAS BALLOON LAUNCH *
- ========================
- The fifth flight of the North Texas Balloon Project will be on 13-Nov-93
- at 08:30 CDT from a yet to be decided launch point south of Fort Worth,
- Texas.
-
- On board for this flight will be a cross band voice repeater with an uplink
- on 445.800 MHz, and a downlink on 147.580 MHz. Also on board will be a GPS
- satellite receiver linked to a packet transmitter. This will allow ground
- stations to 'see' where and how high the payload is. The packet telemetry
- downlink will be on 144.290 MHz, and ground stations may also digipeat
- through this beacon using an uplink frequency of 145.890 MHz. The callsign
- for the digipeater is W5SJZ-6.
-
- A launch net will be conducted on 7155 KHz starting about 60 minutes or so
- prior to launch. A local net will be conducted on 146.760 MHz for those in
- the Fort Worth, Texas area. Net Control callsign will be W5SJZ (Lockheed
- Amateur Radio Club)
-
- Reception reports are welcomed. Please contact the mission coordinators on
- the HF or VHF nets. QSL cards will be available for all who send in
- accurate reception reports on the high altitude balloon payload.
-
- Questions regarding this mission should be directed to:

-
- David, ELNEC (antenna analysis program) says that your 20m dipole
- has a radiation impedence of around 1-j2000 on 80m. That means an
- antenna-end SWR of greater than 100/1 on whatever transmission line
- you are using. The 40m impedence is a little better at 12-j1000.
-
- Almost none of your power is making it to the antenna. The obvious
- solution is a longer antenna. If you absolutely cannot put up a
- longer antenna, you can disconnect your transmission line at the
- transmitter end, short the two conductors together, and feed it
- as a single-ended "long-wire" on 80m using the "wire" output on your
- MFJ-941.

-
- BTW, this is the sort of thing I was thinking of when I posted a followup

- what's stamped on the line, or what's in a book, or what you measure:
- it is what it is. Any of the others is only an approximation.
- Measurements can come very close, but they can also be very far off if
- you happen to make an error in the application of the instruments you
- use or if the instruments are out of calibration. By using proper
- standards and procedures, you can minimize the measurement error, and
- probably get the best approximations through measurement.
-
- As others have pointed out in a bit different context, you can do a lot
- toward checking the accuracy of a line measurement if you do the
- measurement over a range of frequencies. If the parameters you are
- trying to measure don't vary like you'd expect (and your expectations
- are right ;-), then suspect the measurement.

- Subject: GAP Eagle DX-VI Problems
- To: info-hams@ucsd.edu
-
- Recently I purchased a GAP Eagle DX-VI vertical HF antenna. The
- 10, 12, and 15 meter bands give very good SWR readings. However, I'm
- having problems with 17, 20, and 40. All three bands have unacceptably
- high SWR readings. On 40, the GAP seems to resonate up near the top
- of the band (rather than in the middle). On 20 and 17, the SWR doesn't
- seem to vary much with frequency.
-
- I have called the guys at GAP three times now. They have given
- me many suggestions, but none of them have worked. I've tried the
- antenna on the ground as well as on my roof. I've tried 3 different
- types (and lengths) of coax. The antenna appears to work better on
- the ground, by the way. There are no large metal objects nearby.
- They keep telling me "If it's assembled correctly, and nothing nearby
- is coupling to it, it will work".
-
- Has anyone else out there bought one of these and got it to work?
- Does anyone know the theory behind this antenna? There is a capacitor
- at the top of the antenna. The guy at GAP said this cap could be changed
- to change the center of 40m coverage. Has anyone else had to do this?
-
- Please share any of your GAP experiences (good OR bad) with me.
-
- Thanks,

- To those trying to help find Plectron:
-
- Thanks for your assistance.

- Plectron
- Plectron Place
- P.O. Box 960
- Imboden, Arkansas 72434
-
- telephone 1-(501)869-2877

- They still sell monitor receivers, so I sent for product
- literature. Parts and manuals for their older monitor
- receivers are also available.

- Be a little careful trying to replace single cells. The new one is
- not likely to be well matched with the old ones, particularly if the
- old ones have been in service a while. Also, there's a question about
- the cell design: if you look in a DigiKey catalog, you will see quite
- a number of different types of cell, all the same physical size.
- (rapid charge, high capacity, high rate of discharge, ...)
-
- If you look in the back pages of QST or CQ, you will find ads from
- battery places like WW Associates (and two or three others) for
- replacement battery packs, both complete packs and the "inserts."
- An "insert" is simply the set of nicads all wired up and packaged in
- the proper physical configuration. On the Icom pack I've worked on,
- there were screws to remove to take the pack apart; replacing the
- insert was straightforward, and no glue was required. I'd expect
- on almost all packs to find screws or plastic snaps holding it
- together.

- One at a time! The finals have SWR shutdown protection which does
- a good job of protecting the finals. They begin to shutdown, I
- believe, at 2.5:1 SWR. Note, you still have output, just less.
- The noise blanker isn't the best on the market, but it does a good

- blanker. You can download this mod from the Kenwood BBS at

- Very! It is a solid way of mounting your radio.

- Good Luck and Have Fun. I have used my 430 for 8 years, some
- mobile, some at home, and I really like the radio. It has a
- couple of anomolies, but nothing that precludes it from being one
- of the best mobile rigs out there.
