Subject: AEA LogWindows
To: info-hams@ucsd.edu
Have not received many comments or reviews since my posting a couple
weeks ago on the new AEA LogWindows program. Am still interested in
hearing how others like it.
I (FINALLY) got mine to work this morning. Have received excellent
- but fruitless - hand holding from Tom at AEA. My problem was that
ICOM 751A on Port 1 and AEA PK232 on Port 2 were not compatible
with the program. I kept getting "time out" messages. AEA theorized
this to be an IRQ conflict with my modem in Port 3. After a number
of gyratons, I merely swapped Port 1 and Port 2 and the auto-log
feature works like a charm.
Mehtods to remember if you should happen to chance on the same problem.

SOLAR AND GEOPHYSICAL ACTIVITY INDICES FOR 05 MAY, 1994
-------------------------------------------------------
NOTE: Electrons at greater than 2 MeV continued at high to very high levels
today. The background x-ray flux was less than A1.0. Values less than
about a class B1.0 should be considered somewhat unreliable.

SYNOPSIS OF ACTIVITY
--------------------
Solar activity was very low. No events were observed.
Region 7714 (S14W05) is the only spotted region and is growing
slowly.
Solar activity forecast: solar activity is expected to be
very low.
The geomagnetic field ranged from unsettled to storm
levels - minor storm at middle latitudes and major storm at
high latitudes.
STD: Energetic electrons at greater than 2 MeV have remained at
high to very high levels today at geosynchronous altitudes.
Geophysical activity forecast: the geomagnetic field is
expected to be mostly active during the day with storm
conditions possible at local nighttime. Activity levels should
slowly diminish over the forecast period.

Minor Storm 25/15/05
Major-Severe Storm 10/05/05
HF propagation conditions continued below-normal over the
high and polar latitudes. Very gradual improvements in
propagation conditions are expected over the next 72 hours,
although a return to near-normal conditions is not expected
until next week.

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
Loop = Loop Prominence System,
Spray = Limb Spray,
Surge = Bright Limb Surge,
EPL = Eruptive Prominence on the Limb.

The International Callbook is one source. The Buckmaster CD-ROM is
another, if the April '94 edition has Argentina (the Oct. 93 one
doesn't). He may also have a QSL manager. And the slow way is
through the ARRL Outgoing QSL Bureau, if you're an ARRL member.
Congrats on the first DX!

Our licenses are lifetime, too. It's the *station* license that costs $26
per annum.

Tim: If you'll fax me a request on Monday at 312 793-3195 I'll send you a
copy of the bill pending in the Illinois legislature. Florida and Washington
have already passed theirs. These bills essentially say that "no municipality
may
regulate antennas in violation of PRB-1." It's a bit of a stretch to claim that
this
is a real limit on town zoning laws, but does require that the town take into

No -- perhaps you didn't check the box after all, or perhaps the folks
in Gettysburg missed it. No big deal; you can still fill out and send
in another 610 requesting a new call sign. You'll get a 2x2 Advanced
callsign back in the same 8-10 weeks.

SKYCOM Announcement: (403) 756-2386
---------
SKYCOM Version 1.0b has been released. This is an enhanced version of
the powerful High Frequency Ionospheric Signal Analyst software package.
Version 1.0b permits you to define a dictionary of locations or cities
or "zones" of unlimited size. Select transmitter and receiver locations
simply by typing the name of the sites or by displaying the defined
sites on a VGA-quality map (with the sunrise/sunset terminator grayline,
location of the overhead Sun, and locations of the critically
influential auroral zones and more, all superimposed on the map) and
selecting the desired locations with your mouse. Instantly determine
distances between any two geographical locations. Define your own
colors for SKYCOM's menus and prompts, and more. Numerous additional
algorithmic enhancements have also been incorporated into this revision.
Produce VGA-quality global "snap-shots" of the state of the ionosphere
(maps of maximum usable frequencies for variable distances, maps of
critical F2-layer frequencies, maps of the height of maximum electron
density, maps of solar zenith [or elevation] angles, maps of the
magnetic field of the Earth, and much more). Ray trace signals through
one of two realistic (IRI) models of the ionosphere. Handle up to 99
user-defined regions of sporadic-E. Generate broadcast coverage maps of
signal quality, signal multipathing, ionospheric focusing/defocusing of
rays, and more. Rigorously compute maximum usable frequencies between
any two geographical points using actual ray-tracing results.
SKYCOM produces high-precision results and handles practically every
type of geophysical disturbance that can affect radio communications,
from solar flares to geomagnetic storms to devastating polar cap
absorption to sporadic-E and more. SKYCOM is a serious and
user-friendly software product for serious communicators.
For more information, call the recorded SKYCOM announcement (approx 3
minutes) listed above or send e-mail to: Oler@Ultrix.Uleth.CA. This is
a software package no radio communicator or listener should be without.

CONFIDENCE LEVEL: 70%
NOTES:
Predicted geomagnetic activity is based heavily on recurrent
phenomena. Transient energetic solar events cannot be predicted reliably over
periods in excess of several days. Hence, there may be some deviations from
the predictions due to the unpredictable transient solar component.

NOTES:
This graph is determined by plotting the greater of either the planetary
A-index or the Boulder A-index. Graph lines are labelled according
to the severity of the activity which occurred on each day. The left-
hand column represents the associated A-Index for that day.
Q = Quiet, U = Unsettled, A = Active, M = Minor Storm,
J = Major Storm, and S = Severe Storm.

NOTES:
The 10.7 cm solar radio flux is plotted from data reported
by the Penticton Radio Observatory (formerly the ARO from
Ottawa). High solar flux levels denote higher levels of
activity and a greater number of sunspot groups on the Sun.
The 90-day mean solar flux graph is charted from the 90-day
mean of the 10.7 cm solar radio flux.

NOTES:
These VHF DX prediction charts are defined for the 30 MHz to 220 MHz
bands. They are based primarily on phenomena which can affect VHF DX
propagation globally. They should be used only as a guide to potential
DX conditions on VHF bands. Latitudinal boundaries are the same as those for
the HF predictions charts.
