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.

* 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.

Hmmm... Let's say I have a length of RG-62 (but don't know that's what
it is), and it has an attenuation of about 5dB. If the length (in wavelengths)
is right (odd number of 1/4 waves), that should give you pretty close to 1:1 SWR
as measured with a 50 ohm SWR bridge. But a bit different electrical length
(even number of 1/4 waves) could give you a 4:1 SWR, for the same attenuation.
So I don't see how the first three sentences above work out...
BTW, this is the sort of thing I was thinking of when I posted a followup
a few weeks ago suggesting that if you want to measure some line parameter
(it was loss at that time), you should be careful to calibrate
your measurements--to check them against some known values. I'll repeat
it here: the loss, or the impedance, or the electrical length, isn't
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,

When I bought my FT530, I negotiated the mod in with the
price and got it effectively for $10. Whoever is charging
over $100 is ripping people off. The mod is very simple;
I just had the store do it so that warranty coverage would
not be affected (the store is a Yaesu service center).

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
job. Make sure that your radio has the mod for the noise
blanker. You can download this mod from the Kenwood BBS at
1-310-761-8284.

No, but depending on where you mount the radio, you might want one
anyway.

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.
