To: info-hams@ucsd.edu
Dateline: Madison Wisconsin
The Madison Area Hamfest is an excellent swapfest drawing hams from several
states. It's held each spring at the Dane County Expo Center in its Forum
Building.
It's $5 at the door with doors opening at 8:00 am.
For more information you can contact Jim Waldorf KB9AQQ @ 608.249.7579 It is
sponsored by the Madison Area Repeater Assoc.
Even if you're going to Dayton this is one of the best in the Midwest!

SYNOPSIS OF ACTIVITY
--------------------
Solar activity was very low. Only weak B-class x-ray and
sweep activity was reported this period, all before 02/1300Z.
For the first time since 22 Sep 93, the disk is spotless. Of
the two spotted regions reported yesterday, Rgn 7696 rotated
off the disk and Rgn 7698 (S14W36) lost its spots.
Solar activity forecast: solar activity is expected to be
very low.
The geomagnetic field has been at mostly quiet to unsettled
levels until 02/0900Z when the field experienced active to
minor storm levels. A favorably positioned recurrent coronal
hole is believed to be responsible for activity increases.
Geophysical activity forecast: the geomagnetic field is
expected to remain at mostly active to minor storm levels at
middle latitudes and minor to major storm levels at higher
latitudes. Isolated periods of severe storm conditions can
also be expected. Based on recurrence, these conditions are
forecast for the entire period and are expected to persist
through at least 9 April.

HF propagation conditions were near-normal until the
latter part of the UTC day when levels of auroral and
geomagnetic activity increased to storm levels. This produced
below-normal propagation for transpolar and especially for
transauroral circuits. Conditions will continue to
deteriorate, affecting the middle latitudes over the next
several days. Major to severe geomagnetic storming and strong
levels of auroral activity could give frequent periods of
useless propagation over the high and polar latitude regions,
with poor to occasionally very poor propagation over many
middle latitude regions. Conditions are not expected to
improve during the next week.

SYNOPSIS OF ACTIVITY
--------------------
Solar activity was very low. The disk remained spotless
for the second day in a row.
Solar activity forecast: solar activity is expected to
remain at very low levels.
At middle latitudes, the geomagnetic field has been at
mostly active to minor storm levels with isolated periods of
major to severe storm levels observed. High latitudes
experienced mostly minor to major storm levels with some
isolated periods of severe storm conditions. The storm
conditions are believed to be a result of a favorably
positioned recurrent coronal hole. The greater than 2 MeV
electron flux reached high levels at 03/1845Z. (STD: Overall
electron fluence levels were generally at moderate levels.)
Geophysical activity forecast: the geomagnetic field is
expected to remain at mostly active to minor storm levels at
middle latitudes and active to major storm levels at high
latitudes. Isolated periods of major storm levels at mid lats
and severe storm levels at high lats can be expected. Based on
recurrence, these conditions are forecast for the entire period
and can be expected to persist through 9 April.

HF propagation conditions became strongly disturbed over
the high and polar latitude paths with the arrival of the
anticipated geomagnetic storm. Strong fading and absorption
along with heavy multipathing has degraded most transpolar and
transauroral circuits. Conditions were generally extremely
poor to unusable with frequent radio-blackout conditions for
high and polar latitude signal circuits. Middle latitude paths
have also been moderately affected with well below normal
signal quality, reduced MUFs and strong levels of fading and
absorption. Low latitudes observed near-normal propagation
with occasional minor signal degradation bringing overall
signal qualities within the good to fair range. Conditions
will continue strongly degraded over the next 24 to 72 hours
with very little improvements (particularly on the upper middle
to polar latitude paths) expected over the next week.

Ah, but when you're talking about a 45MHz split, as opposed to a 600kHz
split, the "bandpass" and the tuning of the cavity is HUGE! In fact,
it's pretty well tantamount to a cxirculator than a cavity/duplexer

Sorry for the intrusion, but I was wondering if anyone could email input
on the University of Florida, in Gainesville. I read this group all the
time and I figured I could reach a lot of people quickly this way.
I have an opportunity to study there this summer, particularly in the
psych dept, and I would like input from anyone who studied/lived there,
to help me make my decision. (what the campus is like, how big the school
is, how close the campus is to the real world, about the city, Gainesville,
anything about the campus would be helpful)
I will be unable to read this newsgroup this week, but I will have access
to my email, so please email any responses to sjg@yar.cs.wisc.edu
Thanks much for your help.

Like the Campbell R2 receiver, Jan. 1993 QST! For whatever combination of
reasons, it IS a clean sounding unit. I'll bet his companion phasing SSB
exciter sounds just as good.
