SYNOPSIS OF ACTIVITY
--------------------
Solar activity was low. Region 7629 (S21W13) continued to
simplify, producing two C-class flares in the process. A 17
degree-long filament disappeared from S39E32 early in the day.
A prominence erupted from N13E90 during the latter part of the
period.
Solar activity forecast: solar activity is expected to be
low.
The geomagnetic field varied from unsettled to major storm
conditions over the past 24 hours. This disturbance is
occurring during what had been a recurrent quiet interval over
the past five months. It is not clear as to what transitory
phenomenon caused the storming.
Geophysical activity forecast: the geomagnetic field is
expected to be unsettled to active over the next 24 hours, as
the disturbance wanes. Strictly unsettled conditions should
end the period.
STD: Auroral activity was observed into the northern United
States over the last 24 hours. Several reports of strong
activity were received early in the UTC day, including color
variations and rapid pulsations. Activity has since subsided
substantially. Conditions are no longer visible over the middle
latitudes.

Active 45/35/30
Minor Storm 35/25/10
Major-Severe Storm 10/05/05
STD: HF propagation conditions were well below-normal over
the last 24 hours. Strong geomagnetic and auroral activity
produced a particularly strong corresponding ionospheric
disturbance over the middle, high, and polar latitude regions.
MUFs were depressed by up to 40 percent for high-latitude
paths. This, combined with periods of strong fading,
multipathing, and auroral absorption, resulted in near-useless
propagation for transauroral and many transpolar circuits.
Middle latitude paths also saw periods of strong signal
degradation, particularly during the local night hours.
Conditions began improving fairly rapidly after 18:00 UTC and
are now well on the way toward reaching near-normal levels by
the end of 09 December for most regions. Australian stations
have reported periods of strong continent-wide VHF
communications (including TV) on frequencies approaching (and
perhaps in a few cases exceeding) 100 MHz, likely attributed to
persistent sporadic-E.

Subject: Motorola Radios
To: info-hams@ucsd.edu
I need to know where to find good prices on Motorola radios. The fire
department I belong to in going to purchase some new Hi-Lo band radios
in the near future and we would like to get a good price.
I know this is not a ateur radio request, but I thought someone out
there would know a good distributor of Motorola products. BTW I dont
know the exact model number of the radios yet.
Thanks for any help.
P.S. Please send E-mail to this account (This is the account of a

Subject: Recommendations on HT's
To: info-hams@ucsd.edu
I'm a brand-spanking new ham, and I'm currently radioless. I've heard
or seen good things about the Standard C-168A, Icom IC-W2A, and Motorolas
in general. From a (relatively biased, I might add) local ham group, I
recieved the general consensus that Alinco HT's aren't worth the boxes they
come in. Discussions in this forum have not changed this opinion, although
some people have said that they like their Alinco's. I'm not looking for
flames here, but simply reviews/recommendations for HT's. I'm a college
student (no extra $ here!!!), and I'd like 5W capability. 2m/440 dualband
would be nice, but maybe a dream for the $ I'm willing to spend ($200 tops
for 2m only, $300 for dualband). If anyone has any suggestions/help/extra
radios :-), please email me with them. If I get enough, I'll compile them
and post them on the forum for other new hams like me.
I'm also looking for a TNC, like a KPC-3 or PK-88.
Thanks a lot.

Subject: RF Ground for 2nd story shack?
To: info-hams@ucsd.edu
Another way I have heard to do it is to use old RG-8 type
coax and run the inner connector to earth ground and
a .01 ufd/1000 volt capcitor on each end of the coax going
from the shield to inner connector. The shield then is
floating. What you want to avoid is grounding any 1/4-wave
radials to an earth ground to kill off the RF. You want only
one wire or inner conductor to earth ground and at least
two or three 8-foot ground rods at least 10-foot apart brazened
with hard solder. If you use soft solder or a mechanical
connection, in time you could have a resistance induced into
your ground connection which is no good at RF and maybe DC
return to earth.
I would try the coax with capacitors before I would run 1/4-wave
radials. I think the MFJ ground tuner might be worth having if
you can afford it.

I think there is. The specific pidgin idiom used is one which was commonly
used by Americans to mimic Japanese.
The important thing to remember (and please get this):
The people being offended (Japanese people, Japanese-Americans, and other
Asian people) will very quickly recognize the offensive idiom. They have
been sensitized to that kind of stereotype and are a deal better at realizing
than all the apologists with European surnames who have posted in Scratchi's
defense.
>(The magazine articles included a drawing of the "author" with obviously
>oriental features.)
More like an 'oriental caricature.' Again, an offensive idiom because it
is the way in which the white race mocked or sterotyped the Asian.
>I can understand how the pidgin English might be offensive to some Asians.

That was only one of the stereotypes which operated at that time. Another
was the hapless, amusing little man who is always bowing and saying
'honorable.' 'Oriental people are all very polite, and the women are
very good housekeepers,' to quote my Grandma.
All of these stereotypes are offensive to many Asians. It's a truism that
people don't like to be sterotyped, even with supposedly positive
characteristics. The clearest example is the old saw about rhythm being
"in the blood" of black people. It took many of us a damn long time to
get through our heads that that is really offensive. Most of us have
learned it, by now.
This has been an interesting discussion. It makes it clear to me that
there are still a number of so-called intellectuals who understand very
little about the politics of prejudice. That many of these addresses
seem to come from academic institutions, where there is so much opportunity
to learn what it's like from the other side, is truly sad.

Yes, mine does that too. It's a click with a slight chirp
characteristic to it. I'd be interested in knowing what
the fix is. I've heard that some manufacturer fixes
reduce radio performance :-( Wasn't there a intermod fix
for some brand of HT that simply reduced sensitivity? I
would guess the fix in this case won't... Please post the
outcome of your dealings with Yaesu; I think the community
would be interested.
Peter
PS: Has anyone ever seen a user-written user guide to the
FT530? I come across undocumented how-to's every once in a
while. For example, pusing PTT when the unit is off
changes the time display to reveal the seconds!
