I'm not sure I completely understand what happened, but I think that the USENET
newsgroups were reorganized so that certain topics changed groups, and that the
INFO-HAMS digest is a distribution on the INTERNET that captures only certain
ones (or one) of the USENET groups.  At any rate, it is certainly true that
much, much less is coming over the INFO-HAMS distribution now.  I don't have
access to USENET and so am totally dependent on INFO-HAMS for discussions.  If
the above is true, could INFO-HAMS capture more USENET newsgroups?  Or could
another list be created which does so?  I wish there were a way to see all of
the ham newsgroups on the INTERNET, but would particularly like to see the
equipment trade/sale listings.

<Great score John!

<<80     235      80    W3LPL
<<40     430      90    N3GB, KC3EK

<I am just getting back on the air after about 5 years of inactivity.  In the
<past I did several single 40s or operated 40 from K0RF in multi-multi.  It
<seems to me that the 40 and 80 SSB QSO total for the east coast multi has
<gone way up (in contests were you can't work VEs).  Is there more Europe
<to run now, working more JAs, or are you passing lots of non-mult QSOs
<down to the low bands?

The 40 M score was about 90 QSOs better than LPL had done before, the 80 M
was only about 5 better. The difference between now and 5-8 years ago is mainly
two things: antennas and packet radio.

On 40 Frank has a full size 3 el at 100 feet fixed on Europe, and a rotatable
full size 3 el at 200 feet. I operate a lot of 40 CW from LPL and we will break
2000 Qs on 40 CW when 20 is not a 48 hour band. On 80 he has two high dipoles
and a 2 el wire quad fixed on EU. We didn't work a lot of JAs on 80 (K3ZO has
an 80 M beam here and he worked 24 JAs), and we could only run stations for a
short while on Sat nite.

The packet spotting system really helps the low bands pick up multipliers
without having to give up a run frequency to sweep the bands. Although the
MD/DC cluster doesn't have a lot of night owls, there are enough to keep
the low bands chasing. We do pass a lot of mults from 20 - 40 - 80, as well
as ask high band mults to look for us on the low bands. With all bands running
CT, each band can see what the other bands need, and our mult passing has
gotten a lot better.

If you're not familiar with multiplier passing, it means asking a new
multiplier you just worked to QSY to another band where your also need that
country. In these days on tribanders and no-tune transceivers, 75% of the
people who answer your CQ will QSY, try it. Sometimes even stations running
their own pileup will move, but you will end up with a lot of people in that
pileup who will slash your tires at the next hamfest!

                        --  MAJOR SOLAR FLARE ALERT  --

                                MARCH 13, 1991

                              Flare Event Summary
                           Potential Impact Forecast


                                    --------


MAJOR ENERGETIC EVENT SUMMARY

     Two major solar flares have occurred over the past 6 to 24 hours.  The
first major event began at 12:40 UT on 12 March, peaked at 12:46 UT and
ended shortly thereafter at 12:58 UT on 12 March.  This major flare
attained a class X1.7/2B rating and was associated with a strong Type II
sweep and strong radio emissions at 245 MHz and 10 cm.  This flare was
associated with a 2,000 s.f.u. (solar flux unit) Tenflare which lasted 11
minutes.  A 55,000 s.f.u. burst was also observed at 245 MHz.  This event
is believed responsible for producing a small SID/SWF.  This major flare
originated from Region 6545 at a location of S07E59.  The event lasted a
relatively short 18 minutes.

     Another major high-level M-class flare began at 02:53 UT on 13 March,
peaked at 03:05 UT and ended at 03:11 UT on 13 March.  This event reached a
class M9.0/2B rating and was associated with a moderate intensity Type II
sweep.  It is not yet certain what region this flare originated from.
There is some dispute whether this event originated from Region 6545 or
6538.  There have been conflicting reports.  Some communications problems
have also contributed to the uncertainty.

     Region 6545 (now located at S09E51 at 00:00 UT on 13 March) is
optically and magnetically complex.  It possesses a potent Beta-Gamma-Delta
magnetic configuration and encompasses 23 visible spots in an optical DKI
configuration.  This region was responsible for the X-class flare mentioned
above and is capable of producing high-level major M-class flares and/or a
major isolated X-class flare.

     Region 6538 (which produced very energetic flaring earlier last week)
is also optically and magnetically complex and appears quite formidable in
white light as well as in H-alpha light.  This region also contains a
magnetic Beta-Gamma-Delta configuration, but has been unusually dormant in
flare-activity lately.  This is expected to change at any time, however.
Frequent M-class flaring and possible high-level major M-class and/or
isolated X-class flares are also possible from this region.  A significant
major solar flare from Region 6538 could produce high terrestrial impacts
as well as potentially strong proton and PCA activity.

     A weak proton enhancement was observed near 17:00 UT on 12 March with
protons greater than 10 MeV.  The peak flux attained was about 2 p.f.u..


POTENTIAL TERRESTRIAL IMPACT FORECAST

     Todays first major flare at 12:46 UT on 12 March will not have a
terrestrial impact.  It is uncertain whether the latter major event will
have a terrestrial impact.  The location of this flare is vital in
determining the potential impacts, and the location of this flare is still
uncertain.  If the flare originated from Region 6545, no terrestrial
impacts will likely be observed.  If the flare originated in Region 6538,
which has just now crossed into the western hemisphere, a weak terrestrial
impact may be possible on 15 March.  More significant major flaring from
Region 6538 will be required before potentially strong terrestrial impacts
might occur.

     The Potential Major Flare Warning remains in effect throughout this
week (and possibly longer).  Regions 6538 and 6545 are capable of producing
major solar flares.  Region 6538 is capable of producing proton activity
with major energetic solar flares.  Polar latitudes and satellite
operators/users should be on the alert for possible proton and PCA activity.
Polar radio blackouts are likely if a major proton flare erupts from Region
6538.  PCA activity could keep polar radio blackout conditions constant for
many hours (or possibly a few days if the event is intense).

     Further updates and/or alerts will be posted as needed over the coming
week.

ATTENTION:

     A major-storm level positive magnetic excursion has been measured
locally (northerly middle latitude station) and has been associated with
strong radio signal fading and flutter.  Our station has only been able to
catch the latter part of the larger magnetic disturbance.  The magnetometer
was down for routine maintanence until 01:15 UT.  Hence, we only caught the
falling edge of the magnetic disturbance.  However, from the information we
have gathered thus far, the disturbance locally measured over 234 gammas.
The peak occurred sometime shortly before 01:15 UT, judging by the
signature of the disturbance measured.

     We are not yet sure what the cause of this magnetic storm period is,
or if this is a planetary disturbance.  We have reason to believe this is
a planetary disturbance, and until we can verify the information (very
shortly), we have posted this Potential Geomagnetic Storm Warning.  A
bulletin will follow shortly.

     Until the bulletin is released, please be aware of the potential for
geomagnetic storming, possible strong auroral activity, and possible poor
radio conditions.  The bulletin will formalize the conditions occurring so
far and will list the expected conditions.  A major flare alert will also
follow shortly.

                    Updated Geomagnetic Storm Warning

                /\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\


UPDATED GEOMAGNETIC STORM WARNING INFORMATION

     At approximately 22:00 UT on 12 March, a sudden magnetic impulse was
detected at many magnetic observatories.  Approximately 2.5 hours later,
the geomagnetic field became disrupted.  A major positive magnetic
excursion was measured over most middle and high latitude observatories
accompanied by moderate to strong disruptions on the HF bands.  Only a
single magnetic perturbation occurred, and has been followed by generally
unsettled to active conditions over the middle latitudes.  High latitudes
have experienced minor storming.  Our local magnetometer was down for
routine maintenance at the time of the major magnetic excursion, but was
brought on-line during the declining phase of the perturbation.  The
magnetic excursion (at our site) exceeded 300 gammas and occurred over a
time span of about 10 to 15 minutes (the declining phase).  Other sites
have reported larger excursions.

     The geomagnetic field is not expected to reach storm level thresholds.
Generally active conditions can be expected.  Northern middle latitudes can
expect periods of minor magnetic storming.  High latitudes can also expect
to experience minor storm level perturbations.  Central and southern middle
latitudes can expect unsettled to active magnetic conditions over the UT
day of 13 March.

     The major magnetic excursion was a surprise.  An increase in activity
was expected to follow the magnetic SI, but was not expected to be nearly
as energetic as it was over the middle latitudes.  Conditions at the
present time are relatively stable.  Activity has increased somewhat, but
is not near storm levels except near the auroral zone where minor storming
is in progress.

     Auroral activity has increased significantly over the past several
hours.  Northern middle and high latitudes are witnessing moderate to high
auroral activity.  Some southward migration of the auroral zone has
occurred, but no significant southward migration is expected.  No low
latitude auroral activity will be visible.  However, if major flaring
continues, auroral activity could appear in the lower latitudes later this
week (see the solar flare alerts).

     The Potential Geomagnetic Storm Warning remains in effect at least
until 24:00 UT on 13 March.  An update will be posted early on 14 March or
may be combined with a major solar flare alert if major flaring continues.
