It's time for the Perseids!
The Perseids, the year's favorite shower, should peak Aug 12, ~1130-1400. The shower usually produces meteors Aug 7-24, so don't operate only at the peak time. The radiant circumpolar for north but best after 2300 local time. For MS work, the proper time for maximum "effectivity" is much more important than the peak time. (It was huge in early '90s with passage of comet, but only "traditional" peak expected now). For more, see http://science.nasa.gov/headlines/y2008/22jul_perseiddawn.htm?list90677, PhysOrg.com, and http://www.imo.net/calendar/2008#per

Es Season is here!
There have been a number of reports of tiny openings with one or two signals heard, but the only sizable opening so far occurred on Sunday morning, June 16. It appears to have started about 1400 Z (1000 EDT) and lasted until about 1700 Z. The main Es cloud apparently drifted from Arkansas to Colorado during this time, and there is evidence of one or two additional areas of enhanced E ionization during this time. Contacts were reported in all directions across the center of the enhanced ionization. In spite of the fact that this was a VHF contest weekend, the number of operators who took advantage of the opening seems to have been rather small! Apparently most operators were either in church or were sleeping off a long night of contesting. For those on the DX Robot's alerting list, there were plenty of E-mail notices sent out to alert everyone.

If you haven't signed up yet for PE1NWL's Es Alerting system, you can still do so.
Read the details, get sign-up info on the ESAlerts page.

This alerting system helped warn a number of North American operators of the big opening in 2007 (see the Archived News page for a summary). And it was the only way most knew about the several small openings.

North Americans - Remember to ALWAYS use Es in your messages on the 144 Prop page at http://dxworld.com/144prop.html when you are reporting sporadic E signals, in order to activate the DX Robot.
Using "Es" in all notes concerning Es reception will also insure that your note is included in the North American Es Log summary for that day (found at http://www.xs4all.nl/~amunters/eskipNA.htm).

Do NOT use Es (or es or E skip, or skip, or anything similar) when you are just making comments or asking questions on the "144 Prop page", for these will trigger false alerts!

(It is also interesting to sign up for the European alerts, to see how many more they get than we have in North America. See a real-time European log at http://www.xs4all.nl/~amunters/eskiplog.htm. See animated maps of European openings at http://www.vhfdx.net/spots/map.php) and http://www.vhfdx.net/esmaps.html

And, of course, don't forget to keep watch on 144 MHz Propagation Logger and The APRS VHF Propagation Map for tips.

WHAT is HAPPENING? Right now?
What is happening right now - for VHF propagation, solar conditions, the space environment, meteors, atmospheric weather, etc?
Check the Quick Links above for Web sites that have all kinds of information!
(You may want to bookmark a few of these pages for immediate reference).

VHF DXpeditions - For a list of current and upcoming DXpeditions, including late information that may not be on this page, check http://www.mmmonvhf.de/latest.php.

REAL-TIME VHF Propagation Maps
Gabriel, EA6VQ, has a real-time set of VHF Propagation Maps to his Web site. Once on the map page, you can choose the band and map (Europe, North America or World) you want to watch.
If you leave the window open, it will refresh automaticall every 3 minutes, so you'll always have an overview of the band activity and conditions in real-time. Go to http://www.vhfdx.net/spots/map.php to see this great tool.
(Also, don't forget to check http://www.xs4all.nl/~amunters/eskiplog.htm to see a log of what has happened or is happening over there).

For tropospheric openings on two meters:
You can check Hepburn Tropospheric Ducting Forecast Maps to see his predictions.

Another very useful resource is the APRS propagation map which shows real-time reception of 144 MHz APRS signals and thus can give an indication of both tropo and also Es propagation. These maps are updated every few minutes, so they show what is being received right now. (See May 2005 QST, p. 86, for more information).
(Both of these Web sites are also included in the "Quick Links" box at the top of this page).

JT65 on HF
From Rein PA0ZN - If you listen on 14075/6 you will hear various digital signals, as well as WSJT JT65A. At busy times you might see signals stacked against each other in frequency, even overlapping each other partially, without too many bad effects. There is activity from 160 meters all the way up to 6 meters, with most of it at 14076 =/- 500 Hz. at present. It is world wide and growing. Many of the users run <25 W with vericals from balconies or magnetic loops in living rooms. It is not VHF, but certainly is a form of weak signal communications, such as some of the other new digital modes.
Check the JT65 Terrestrial link at: http://www.chris.org/cgi-bin/jt65talk.
(Thanks to PA0ZN and WB8IMY [July 2007 QST p. 85] for bringing this to our attention. It isn't very often that some mode or type of operation spills over from VHF to HF. I had heard some JT65 signals on 20 meters recently but had not realized that it had become a "whole new mode" for HF operators).

Accessory programs. Do you need a clock-setting program? A program for quickly changing your computer's mixer (volume control) settings for different programs? A screen-grab program? Or other "accessory" programs to help with your VHF, MS, or WSJT operating? Check out the Accessory Page for links to these and a number of other helpful programs. Several of these are necessary for efficient VHF DX operation.

Win XP Users - The popular timekeeping program Dimension 4 won't run? Information on two simple but necessary changes can be found here.
(Dimension 4, lots of other helps including QuickMix, are available from the Accessory Page.

The current version of WSJT - 5.9.7.
(And MAP65 v0.8 is now available for Beta Testing).
The V. 5.9.6 had a significant improvement to the JT65 Deep Search decoder resulting in a big reduction in the number of false decodes. The decoder is also faster. V 5.9.7 includes several enhancements to make operation easier.

Joe has made a few additions and corrections to the new "WSJT6 User's Guide and Reference Manual".
)The User's Guide is available now in a number of other languages, thanks to the help of many people. See Joe's Web site for what is available).
He has also added the new User's Guide to the file that you download and execute to install WSJT. To download WSJT (the program is free), go to the K1JT home page, http://physics.princeton.edu/pulsar/K1JT/ or the mirror site at http://www.vhfdx.de/wsjt/.

Thanks to a number of generous volunteers, CD-ROMs of the WSJT installation and tutorial files are now being made available at very low cost for those without high speed internet connections. If you have problems downloading WSJT over the internet, use the link http://pulsar.princeton.edu/~joe/K1JT/WSJT_distrib1.JPG to find the volunteer in your region, and then send an email to enquire about details.

A tutorial on the use of WSJT 5.9.x has been placed on the WSJT web site, http://physics.princeton.edu/pulsar/K1JT/.
Be warned, though, that the necessary package of sample wave files is about 22 MB in size. You will need a fast internet connection to download it.
And don't forget the Manual for the older versions, available in a number of languages. While the new version has some changes, most of the features are explained in the Manual. If you are new to WSJT, be sure to read it when all else fails!

If you are running W98, have a processor whose speed is 500 MHz or slower, or otherwise cannot run the latest versions, note that the older version, WSJT 4.9.8, is still available and is fully compatible with the latest versions.

Also - MAP65 is a new (July 2007) computer program designed to provide the "back end" of a semi-automated, wideband, polarization-matching receiver for JT65 signals. In works together with Linrad (by SM5BSZ) and suitable RF hardware to receive and decode all detectable JT65 signals in a 90 kHz passband. MAP65 runs under Windows or Linux. Its principal intended application is EME or "moonbounce" on the amateur VHF and UHF bands.

Hurricanes Katrina and Rita
Following Hurricane Katrina, I was at Long Beach, MS, for communications with the Hurricane Katrina relief efforts. Some pictures and brief description at the link (above).
While in Mississippi, I missed the big auroras. However, all HF communications were completely blanked out two afternoons, so we were very much aware of the events! -- W8WN

The 2006 Hurricane Season is nearly here, and predictions do not sound very good! Are you QRV????

What have meteors been doing today? Some meteor observations in near-real-time:

The North American Meteor Scatter Procedures are available at http://www.qsl.net/w8wn/hscw/papers/hscw-sop.html. But almost no one in North America now operates HSCW or slow CW MS, and SSB MS is used only during major showers. FSK441 has become the standard daily mode of MS operation. Thus, a condensed version of the Procedures paper, covering only FSK441, is now available at http://www.qsl.net/w8wn/hscw/papers/fsk-sop.html.

If you're looking for some news or information, expecting it to be here but you can't find it, it has probably already been moved from the Hot News page to the Archived News page or the Really Old News Page.

Some UPCOMING SHOWERS
(many are minor showers) Source - International Meteor Org. (& other supplemental sources).

Shower	Date, Time (UTC)	Rate	Shower Data, ZHR	Notes
NOTE - Except for the sharp peaks of the Leonids and Quadrantids, the exact time of the peak is usually not as important as the location of the shower's radiant (the point in the sky from which the meteors appear to originate). If the radiant is below your horizon, you will experience few if any shower meteors. If the shower is above your horizon, its location (and thus the geometry of the meteor trains) will determine which direction is best at a given time. These things can be determined with OH5IY's MS-Soft or similar programs. But if you're on HSCW, don't wait for even a minor shower. You can make HSCW QSOs any morning with only sporadics! Get on and make those skeds!
Southern delta Aquarids	July 27	20	Long duration	Multiple showers? Radiant drift.
alpha Capricornids	July 29	4	-	Southern Hemisphere shower, but may not exist.
Perseids	Aug 12, 1130-1400 (see notes)	100	The year's favorite shower.	Shower usually produces meteors Aug 7-24. (Huge in early '90s with passage of comet, but only "traditional" peak expected now). Radiant circumpolar for north but best after 2300 local time. For MS work, the proper time for maximum "effectivity" is much more important than the peak time.
Sextanitids	Sept 27, 0400	medium	-	Daylight. Peak possibly a day earlier. This year, possibly a day later.
Draconids	Oct 08, 1030	periodic, to storm levels	-	Periodic, with brief, spectacular storms twice last century & lower rates other years.
Orionids	Oct 20/21	20	Several peaks over several days. Periodic?	May be nearing its peak? Best in Southern Hemisphere Debris from Halley's Comet
Leonids	Nov 17, 0900	10-50	Several peaks possible	Other peaks on Nov 17, at 0022, 0132, and Nov 18 at 2138??? Radiant rises around local midnight.
alpha Monocerotids	Nov 21, 0925	5	variable	outbursts to ~400, 1995, lasting only 5 minutes.
Phoenicids	Dec 06, 0300	3	Usually 3	variable. May reach 100. Southern Hemisphere.
Geminids	Dec 13, 2300 � 2.3 hours	120	Major shower	Parent body, Apollo asteroid 3200 Phaethon. Radiant rises around sunset in north.
Ursids	Dec 22, 0730	10	occasionally up to 50	Two major outbursts in past 60 years.
Many of the above are minor showers (with low rates); but some can cause surprises. There are many other minor showers, but too small to be noticed in forward-scatter communications.

* Data for this shower may be updated later.

To download OH5IY's MS-Soft program, go to http://www.kolumbus.fi/oh5iy. While there, take the time to download his papers on MS. This is the best information on meteor scatter theory that is easily available.

EME - Except for an occasional note, a little concerning JT65, and some of VE7BQH's antenna charts, there is little on this Web site concerning EME. This is due both to lack of time and also because there are already a number of good EME Web sites. For EME information, it is suggested that you start with W5UN's Web site. And for another very good moon-tracking program, see N1BUG's Z-Track.
For satellite tracking programs, start with the AMSAT Web site. (Also try a search for STSPlus and Traksat).
