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. -- -------------------------------------------------------------------------- Jeff Freedman Tacoma, Washington jfreedmn@hebron.connected.com K7JF You come here with a skull full of mush ... -------------------------------------------------------------------------- ------------------------------ Date: Fri, 6 May 94 01:23:08 -0500 From: ihnp4.ucsd.edu!usc!howland.reston.ans.net!noc.near.net!news.delphi.com!usenet@network.ucsd.edu Subject: Amateur Radio and Civil Rights To: info-hams@ucsd.edu YEA!!!!!YEE!!!!!BRAVO!!!!@!........................de N6WR ------------------------------ Date: Thu, 5 May 1994 21:37:07 MDT From: ihnp4.ucsd.edu!library.ucla.edu!psgrain!nntp.cs.ubc.ca!alberta!ve6mgs!usenet@network.ucsd.edu Subject: Daily Summary of Solar Geophysical Activity for 05 May To: info-hams@ucsd.edu /\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\ DAILY SUMMARY OF SOLAR GEOPHYSICAL ACTIVITY 05 MAY, 1994 /\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\ (Based In-Part On SESC Observational Data) SOLAR AND GEOPHYSICAL ACTIVITY INDICES FOR 05 MAY, 1994 ------------------------------------------------------- NOTE: Electrons at greater than 2 MeV continued at high to very high levels today.

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.

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.

Box 357, Stirling, Alberta, Canada T0K 2E0 Accessible BBS System: (403) 756-3008 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. --------- SOLAR AND GEOPHYSICAL ACTIVITY FORECASTS AT A GLANCE ---------------------------------------------------- |10.7 cm|HF Propagation +/- CON|SID AU.BKSR DX| Mag| Aurora | |SolrFlx|LO MI HI PO SWF %MUF %|ENH LO MI HI LO MI HI %|K Ap|LO MI HI| --|-------|-----------------------|-------------------------|----|--------| 06| 072 | G F VP VP 05 -35 65| 05 NA NA NA 03 30 40 25|5 28|NV MO MO| 07| 072 | G F VP VP 05 -30 65| 05 NA NA NA 03 30 40 25|5 25|NV MO MO| 08| 072 | G F P P 05 -25 65| 05 NA NA NA 02 25 35 25|4 23|NV LO MO| 09| 072 | G F P P 05 -25 65| 05 NA NA NA 02 25 35 30|4 23|NV LO MO| 10| 073 | G G P P 05 -20 65| 05 NA NA NA 02 25 35 30|4 20|NV LO MO| 11| 073 | G G P P 05 -20 65| 05 NA NA NA 02 20 30 30|4 20|NV LO MO| 12| 075 | G G P P 05 -20 65| 05 NA NA NA 02 20 30 30|3 18|NV LO MO| 13| 075 | G G F F 05 -15 65| 05 NA NA NA 02 20 30 35|3 18|NV LO MO| 14| 077 | G G F F 05 -15 65| 05 NA NA NA 02 15 25 35|3 15|NV NV LO| 15| 077 | G G F F 05 -15 65| 05 NA NA NA 02 15 25 35|3 15|NV NV LO| PEAK PLANETARY 10-DAY GEOMAGNETIC ACTIVITY OUTLOOK (06 MAY - 15 MAY) ________________________________________________________________________ | EXTREMELY SEVERE | | | | | | | | | | | HIGH | | VERY SEVERE STORM | | | | | | | | | | | HIGH | | SEVERE STORM | | | | | | | | | | | MODERATE | | MAJOR STORM | | | | | | | | | | | LOW - MOD. | | MINOR STORM |** | * | | | | | | | | | LOW | | VERY ACTIVE |***|***|** | * | * | * | | | | | NONE | | ACTIVE |***|***|***|***|***|***|***|***|** |** | NONE | | UNSETTLED |***|***|***|***|***|***|***|***|***|***| NONE | | QUIET |***|***|***|***|***|***|***|***|***|***| NONE | | VERY QUIET |***|***|***|***|***|***|***|***|***|***| NONE | |-------------------|---|---|---|---|---|---|---|---|---|---|------------| | Geomagnetic Field |Fri|Sat|Sun|Mon|Tue|Wed|Thu|Fri|Sat|Sun| Anomaly | | Conditions | Given in 8-hour UT intervals | Intensity | |________________________________________________________________________| 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.
