The tube *should* have less intermod, but if the static operating
conditions aren't right, it can have severe intermod. A usual cause
is too low a plate voltage, and/or too low a standing current.

AO-13 FACES LONG ECLIPSE PERIODS

HR AMSAT NEWS SERVICE BULLETIN 345.01 FROM AMSAT HQ
SILVER SPRING, MD DECEMBER 11, 1993

BID: $ANS-345.01

AO-13 Experiences Long Solar Eclipse Which Affect Transponder Operations
James Miller (G3RUH) of the AO-13 Command Team reports that because of the
long duration of the solar eclipse periods that AO-13 is experiencing, they
have been forced to severely curtail transponder operations.  Some of the
eclipse periods have been as long as 2 hours.  Battery bus voltage has
become so low that the net affect has been that there has been no battery
charging from orbit to orbit.  The safety threshold on the battery bus
voltage is currently set 12.6 volts.  When the bus voltage drops below 12.6
volts, the on-board computer shuts down the beacon and brings all the other
subsystems on AO-13 to a "low-power" state.  Currently, with the trans-
ponders and telemetry beacons turned-off, the total current consumption on
AO-13 is around 1 ampere.  In attempt to remedy this low battery voltage
problem, the Command Team has made an spacecraft attitude re-adjustment to
Bahn Longitude 245 degrees and a Bahn Latitude of -5 degrees.  But under
the current solar eclipse circumstances, even this has not been sufficient
to solve the problem of low battery voltage.  So it was necessary to take
even further steps including turning off all transponder operations on
AO-13 until between Friday December 10 and Monday December 13, 13-DEC-93
around 03:28 UTC.  It is hoped that this will bring AO-13 through this
difficult time period, however, there is no guarantee that the above
actions will be enough.  It should be noted that AO-13's batteries are now
5 years old and the Command Team feels that is may be necessary to take a
close look at the battery charging software and presets to determine if
they need to be adjusted for the age of the batteries.

It is requested that all AO-13 users keep a close "ear" to the telemetry
beacons which can be heard on a downlink frequency 145.812 MHz or 2400.646
MHz for the latest information on the transponder schedule.

The Command Team is always interested in hearing from the user any
"constructive feedback" about AO-13 transponder operations.

The AO-13 Command Team ccurrnetlu consists of the following:

  Peter   DB2OS  @ DB0FAU
  James   G3RUH  @ GB7DDX
  Graham  VK5AGR @ VK5WI

IO-26 SUFFERS OBC CRASH

IK2OVV Explains the IO-26 On-Board-Computer (OBC) Crash

After 45 days of uninterrupted BBS service on IO-26, on 8-DEC-93 at
approximately 11:30 UTC, ITAMSAT IO-26 suffered a crash during a pass over
Europe.  IO-26 is now in an undefined status, with its trasmitter on but no
MBL telemetry; the Command Team will try to regain control of the satellite
in the next passes over Europe.  The cause of the crash is still unclear;
the Command Team is investigating on some new software used to access the
BBS services.  In the past, some other MICROSATs crashes were due to bugs
found in the user software.  ITAMSAT Command Team, while recommending users
not to uplink to the satellite at this time, would like to receive reports
about IO-26, especially regarding the presence of just the HDLC flags on
the downlink or some sort of telemetry, either MBL or PHT style.  However,
after examining the memory dumps taken from IO-26, Alberto Zagni (I2KBD)
and Harold Price (NK6K) have decided to begin the uploading of the high-
level software to restore IHT (ITAMSAT Housekeeping Task) capability.
The cause of the crash is still unknown; I2KBD and NK6K are working on
the memory dumps, but the crash destroyed part of the internal logs kept
by the high-level software.  Since the crash happened as one of the Ground
Command Stations in Milan was uplinking to the satellite using a new ground
software (which has not yet been fully tested), there is chance that this
was the cause of the crash.  The ITAMSAT Command Team has decided not to
turn the BBS on after the reloading of the software; the Team will start
some Whole Orbit Data (WOD) collection in order to fully optimize the
energy budget onboard the satellite.  This will enable IO-26 to have higher
power settings on the downlink.  It is estimated that the high-level
software will be working by this soon; stay tuned on the downlink for any
news!

The ITAMSAT Command Team would like to thank again Harold Price (NK6K)
for the great help in debugging the memory dumps and the Eyesat Command
Team for helping during the initial recovery.

ITAMSAT Command Team can be reached via Internet as [e-mail]
or [e-mail], and on Compuserve HAMNET.

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 NCS do not call on frequency, any
participant is invited to act as the NCS.

IO-26: ITAMSAT sufferred a system crash after 45 days of flawless
       operations.  The command team is gathering data to try to determine
       the source of the problem.  They state that the transmitter is on,
       but the BBS is not open.

AO-16: Operations are normal. [WH6I]

LO-19: Operations are normal. [WH6I]

KO-23: Functioning normally.  There have been some questions regarding
       image files.  When WH6I see some images on KITSAT, he trys to list
       them, but files on that satellite are only active for maybe 5-6
       days depending on how much new material is uploaded.  Therefore, by
       the time this status report makes it to the ANS status report,
       the files may be gone.  Satellite image files on KITSAT have names
       in the form KAI?xxxx where ? is either W or N to indicate a WIDE
       or NARROW view image.  The "xxxx" is a serial number.  These files
       are about 350Kbytes large and can be seen in the directory in PB by
       hitting F4 to see the list of files generated by the satellite.
       They are usually in pairs with a wide and narrow view file.  These
       files are downloaded just like anyother file.  The program DISPLAY
       which is often up on the birds willdisplay these images, and it will
       display whatever there is in the xxxx.ACT file of the image, so that
       you can look at a partial download and decide if it is worth
       pursuing. [WH6I]

RS-10: After a period of inactivity, the RS-10 QSO robot is QRV again. The
       downlink is approx 29.403 MHz, and uplink is +/- 145.820 MHz.  If
       you are "into" the robot receiver, your CW from the few KHz wide
       passband will be retransmitted on the robot's fixed frequency.  The
       speed of your CW response is not important; it just needs to be
       steadily and cleanly sent.  K0BJ notes that he just changed from a
       vertical dipole to a J-pole.  It seems so far to be about as bad
       with QSB as the dipole, but the J-pole did seem to peak more in the
       longer, low-elevation parts of the pass.  The next experiment K0BJ
       will perform is with a turnstile antenna.

POSAT: CT1ENQ would like to inform that the Portuguese satellite (POSAT) is
       now prepared for amateur radio use.  Please contact Portuguese AMSAT
       group, AMSAT-PO, for more information.

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

            HF propagation conditions were near-normal over the low
       and middle latitude paths.  High and polar latitude paths saw
       near-normal propagation intermixed with occasional isolated
       minor signal degradation, mostly during the local night sectors
       and on paths transiting the sunrise sector.  These conditions
       will likely persist over the next several days.  Near-normal
       propagation should continue over the middle and lower latitude
       paths.  MUFs have been and likely will remain depressed by up to
       approximately 20 to 30 percent.

SYNOPSIS OF ACTIVITY
--------------------

             Solar activity was very low. All regions on the disk were
       quiet and stable.

            Solar activity forecast:  solar activity is expected to be
       very low to low.

            The geomagnetic field was predominantly quiet to unsettled.
       Some brief isolated active periods occurred at high latitudes
       from 0600-1200UT.

            Geophysical activity forecast:  the geomagnetic field is
       expected to be generally unsettled for the next three days.

                        Major-Severe Storm    01/01/01

            HF propagation conditions were normal over the low and
       middle latitude regions.  However, conditions over the high and
       polar latitude regions continued to be below-normal with
       relatively poor propagation.  Poor propagation has been
       confined mostly to the night and sunrise sectors.  Although
       conditions may improve somewhat over the next several days,
       provided geomagnetic activity remains quiet, propagation will
       likely be slow to recover due to the weak state of the
       ionosphere.

NOTES:
     All times are in Universal Time (UT).  Characters preceding begin, max,
     and end times are defined as:  B = Before,  U = Uncertain,  A = After.
     All times associated with x-ray flares (ex. flares which produce
     associated x-ray bursts) refer to the begin, max, and end times of the
     x-rays.  Flares which are not associated with x-ray signatures use the
     optical observations to determine the begin, max, and end times.

     Acronyms used to identify sweeps and optical phenomena include:

          II        = Type II Sweep Frequency Event
          III       = Type III Sweep
          IV        = Type IV Sweep
          V         = Type V Sweep
          Continuum = Continuum Radio Event

1.  Political rectitude sucks!  It has deprived us of access to some of our
history and classics, merely because it might "offend" someone.  How can
you understand yourself if you cannot access the information on your
background.  Case in point, I cannot see Disney ever re-releasing _Song of
the South_, which was a delightful movie, because it is a stereotype.

2.  I read a couple of issues of CQ back in the late '50's, and found it
puerile then (the Scratchi articles definitely contributed to the
impression), and I was only a teenager at the time.  The posting was
interesting nostalgia, but the literary quality was...

3.  Isn't this an _amateur radio_ group??  CQ real ham stuff!

The concepts aren't easier. In fact they receive less in depth
treatment now than they did in earlier works, so they are actually
harder to understand. What I'm talking about is prose style. This
isn't confined to the Handbook of course, US Army tech manuals have
also had to be rewritten at a lower reading comprehension level.
This means smaller words, shorter sentences, etc. It's not quite
at the "See Spot run." level yet, but that's the direction.

The assumption is that they have a grasp of the English language. Even
college graduates today often have smaller vocabularies, and grasp of
sentence structure and internal logic, than 8th graders of 20 years ago.
This in turn leads to lower comprehension levels which then requires much
more verbose text to get across the same point that would have been grasped
easily a couple of decades ago.

>IMHO that 2.25 inch thick manual is plenty to start with.

Oh, don't get me wrong, there's still a wealth of information in the
Handbook. I just find it a less usable reference than in earlier years.
As an example of what I consider a good handbook, I'd recommend the
_Bosch Automotive Handbook_. It's clear, concise, and complete in a
2.54 cm thick pocket book. The important concepts, data, and forumlae
needed for effective automotive design are all in there. And they are
easily accessed thanks to excellent organization, indexing, and layout.
A radio handbook as well written and edited need be no larger.

With our current Handbook, I find myself having to apply random searches
to access particular information, and then having to slog through too
much verbage to get to the point. And despite all that verbage, fundamental
questions go begging. For example, nowhere in the current Handbook will you
find a coherent explanation of *why* an antenna radiates, though there's a
chapter on antennas. I'd say that's pretty fundamental to amateur radio
wouldn't you? Maxwell deserves better, and so do we.
