If I were you, I'd just try the line as is without any special
transformers. The slight system losses, if any, caused here would
certainly be offset by the rather low loss characteristic of this big
line. In general, the theoretical VSWR in a 75/52 mismatch would
roughly be just that - 75/52 = 1.4. Of course, there are a number of
factors here. The odds are greater than 50/50 that you would get great
results without any special transformers. Have that Bird wattmeter
handy and just go for it. If there are problems, then worry about it.
I routinely use foam RG6 and F-connectors/adapters wherever most people
would use (awful) RG58. Measurements with the Bird wattmeter or the
IFR have confirmed no real problems with this. In the ultimate heresy,
I even connected up my Radio Shack CB transceiver with F-connectors and
RG6; no problem. Similarly, my Icom U400 radio didn't mind it a bit at
UHF for 20' (I prefer super low loss 9913 for longer runs).
In the (very unlikely) event that you need transformers here, you would
probably want to make the "coaxial" type from instructions in antenna
books or occasional Ham Radio articles, etc..

AO-16 BBS TEMPORARILY OFF
HR AMSAT NEWS SERVICE BULLETIN 104.01 FROM AMSAT HQ
SILVER SPRING, MD APRIL 14, 1991
TO ALL RADIO AMATEURS BT
Filled Memory Buffers Cause Temporary Outage of AO-16/LO-19 Bulletin Boards
This week the AO-16 file server software, known as FTL0, encountered an
anomaly which caused the AMSAT Software Engineers "scratch their heads"
for awhile trying to figure out what had happend. It appears that a
software bug in the file server caused many memory buffers to fill
up but not be allowed to release when they were finished being used.
Memory buffers are quite common in BBS and packet TNC software because
they hold the packets until they are ready to be sent to the
proper memory location or until transmitted. Thus, when uploading or
downling a file, the contents always pass through numerous buffers both
in the orbiting software and in ground station equipment.
NK6K feels that it took a very special set of circumstances for this problem
to manifest itself. One of the conditions was heavy usage of the BBS.
NK6K has completed work on a "patch" which has fixed the problem, which
should not be a concern in the future. It is believed that this is
the same problem which caused LO-19 to crash about ten days ago. Both
AO-16 and LO-19 will have their file server software "patched." The
advantage of "patch" procedure is that no files will be lost on the
spacecraft and a complete reload of the BBS software will not be necessary.
It is the opinion of the Software Engineers that this sort of problem will
eventually disappear and users will be left with a stable and problem-free
file server system.

SAREX FSATV OPERATION
HR AMSAT NEWS SERVICE BULLETIN 104.02 FROM AMSAT HQ
SILVER SPRING, MD APRIL 14, 1991
TO ALL RADIO AMATEURS BT
Successful Fast Scan Amateur TV Reception by STS-37
Ken Cameron, KB5AWP, Pilot on the Space Shuttle Atlantis, reported good
FSATV reception from the selected ground stations on at least four orbits
of the STS-37 space shuttle Atlantis mission. Typically, his reports were
been brief because his talk back on 2 meters caused some interference to
the video. He also asked for FSATV transmissions which he recorded on
a VCR in the shuttle while he was too busy with other duties to be in
attendance. Picture quality was reported as P4 or better. Most pictures
were black-and-white, but some color reception was reported.
This is the first Full Motion Video signal ever received by any orbiting
manned spacecraft. In a past SAREX Mission, STS-51F, (which carried Tony
England, W0ORE) Slow Scan TV was uplinked from ground based stations. The
FSATV experiment is being looked at by NASA as an inexpensive mechanism to
transmit detailed imaging information to the astronauts while in orbit
Only a handfull of stations were chosen to attempt the FSATV experiment with
STS-37. An STA from the FCC was required because the wide bandwidth required
for FSATV (6 MHz) could not be completely contained in the 435 - 438 MHz
Satellite sub-band of 70 cm Amateur band. The succesful uplinking stations
were using moonbounce or near-moonbounce class transmissions, several
hundred watts of power to antenna arrays of much higher gain than a typical
OSCAR station.
AMSAT congratulates KC6A, WA4NZD and N9AB for their success with this Shuttle
"First". Also participating in the experiment was W5RRR, WB4APR and KE4PT.
However, due to unfavorable orbiter attitudes during their designated
transmission periods, they were unsuccessful in having their signal received
by STS-37.
ANS thanks Gerry Creager, N5JXS, and Andy Bachler, N9AB for the information
for this bulletin]

NEW AO-13 TRANSPONDER SCHEDULE
HR AMSAT NEWS SERVICE BULLETIN 104.04 FROM AMSAT HQ
SILVER SPRING, MD APRIL 1APRIL 14 1991
TO ALL RADIO AMATEURS BT
AO-13 Spring Schedule Announced, AO-10 Not Presently Available
The current schedule is:
Off : MA 220 to MA 035 |
Mode-B : MA 035 to MA 220 |
Omins : MA 240 to MA 060 |
Once the magnetorquing is completed, the "27 March 91" schedule will be
instituted.
The AO-13 transponder schedule through 19 June 91 will be:
Mode-B : MA 000 to MA 095 !
Mode-JL : MA 095 to MA 125 !
Mode-LS : MA 125 to MA 130 !
Mode-S : MA 130 to MA 140 !
Mode-BS : < discontinued > !
Mode-B : MA 140 to MA 256 !
Omnis : MA 240 to MA 030 !
The target Spacecraft attitude (once magnetorquing is complete) is:
BLON = 180 BLAT = 0
Currently, OSCAR-10 is obviously not receiving sufficient solar panel
illumination to support even the beacon much less the transponder.
PLEASE DO NOT attempt to use OSCAR-10 until further notice. This period
of dormancy is expected to last for several months. As soon as OSCAR-10
can support Mode-B transponder operations it will once again be released
for general use. Early reports of OSCAR-10's beacon returning to full
strength can be sent to VK5AGR @ PACSAT-1, @ UOSAT-3, @ 8J1JBS, or @
VK5WI. 73, Graham VK5AGR

I'm COMPLETELY new to the idea of Ham radio stuff,
pretty much. But I've been toying about learning
Morse code and getting a licsense, now I've heard
about the elimination of the code requirement for
the "technician" class so could anyone tell me how
to prepare for and WHERE TO TAKE THE EXAM TO GET A
TECHNICIAN CLASS LISCENSE????

Wow, this is really amazing considering that GCA-1000 Most Accurate
Clock really isn't (all that accurate). I suppose that if you wanted
time to the nearest second or tenth, its probably OK, but don't bother
with the RS-232 interface. For a WWV synchronized clock, it really
does a crummy job for semi-serious timekeeping. There plenty of room
for improvment in the RF section as well as the RS-232 interface.
Its adaquate for sticking on the shelf and looking at it for the current
time, but don't get too excited about using it for precision time.

Don't bother with plugging your Mac into the transformer. Macs use switching
power supplies which run on anything up to 240v. Just get the appropriate
physical adapters for the line cord plug to fit into the wall socket outlets.
Depending upon your clock radio ... it may or may not lose time on 50Hz.
Mechanical ones will, almost certainly (10 minutes/hour). Some digital ones
may, depending upon the label on the back/bottom of the clock radio.

POTENTIAL MAJOR FLARE WARNING
/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\
April 14, 1991
ATTENTION:
Region 6583 has developed a beta-gamma-delta magnetic configuration and
is continuing to grow in size and complexity. Some fairly good shear also
exists in this region, which has resulted in several M-class flares over the
last couple of days. This region (located at N09E34) is now moderately
large, and contains 57 spots in an EKI optical configuration. This region
could spawn a major class M or X flare anytime now. It could also produce
frequent low level M-class flares. Potential proton activity from this
region is not yet a great threat, although the risk is increasing daily
should a major proton flare erupt from this region.
Region 6580 (N29W10) has also developed a clear delta configuration in
its spot complex, and is also exhibiting growth and increased complexity.
This region is capable of spawning low-level M-class flares and may become
capable of producing more intense major activity soon, if growth continues.
Region 6555 (the major activity center responsible for seven large
X-class flares and the major geomagnetic storm of 24-26 March) is showing
signs of returning back into view on the east limb. Surging was observed on
the southeast limb near 12 degrees south solar latitude. Extensive plage is
also visible in that vicinity.
An optically uncorrelated class M3.1 x-ray burst was observed beginning
at 08:41 UT, peaking at 08:52 UT and ending at 10:07 UT. This long-duration
event could have been produced by returning Region 6555 (which will be given
a new number shortly). We should know within the next 48 hours whether this
region has decayed significantly or not since it disappeared from view around
the west limb on 31 March.
Watch for possible major flare alerts.
