00:00:11: on this

00:00:11: shortwave

00:00:12: bands.

00:00:28: Dayton is far more than just a convention.

00:00:47: It's where friendships are built, technology is celebrated innovation comes alive and the international amateur radio community comes together through shared passion for this unique hobby.

00:01:00: That exactly why today we would especially like to send warm greetings to our American Amateur Radio Friends Congratulations on an outstanding event and thank you for connecting the worldwide amateur radio community through this extraordinary gathering, For so many decades.

00:01:19: For hams around The Globe Dayton is a dream A destination And symbol of how vibrant and alive Amateur Radio still Is today.

00:01:29: Whether You are there in person Walking Through exhibition halls Discovering new technology Meeting old friends Or simply enjoying unique atmosphere We wish all of you a fantastic hamvention.

00:01:42: twenty-twenty six filled with great conversations, new contacts and of course outstanding DX connections.

00:01:53: And we also have one small personal request if you enjoy DX Weta please tell your fellow amateur radio operators about it and share the link to our podcast.

00:02:04: in The International Amateur Radio Community Our hobby thrives on exchanging experiences, sharing knowledge and enjoying unforgettable moments together.

00:02:25: The

00:02:39: local time zone is Eastern Daylight Time.

00:02:42: Researched forecast values for this period indicate a solar flux of one hundred twenty on Friday, one-hundred-twenty on Saturday and one-hunty-five Sunday.

00:02:53: The predicted planetary A index is twenty five, twenty and twenty with daily KP peaks reaching five each day.

00:03:01: What it means that overall solar support for HF propagation is decent but geomagnetic conditions could become noticeably unsettled at times.

00:03:10: That is exactly why this DX week around Dayton, Is not simply a classic fair weather shortwave week But rather a week for attentive operators who know how to take advantage of quieter geo-magnetic windows.

00:03:23: For Xenia sunrise occurs at approximately six twenty one am on Friday Six twenty AM Saturday and six nineteen AM Sunday local time.

00:03:34: That places the morning gray line roughly between five thirty-five a.m and seven o'clock five a. m. Sunset occurs around eight forty three p.m on Friday, eight forty four p.M.

00:03:44: On Saturday an eight forty five P.M.. On Sunday.

00:03:48: The evening grey line therefore runs approximately from eight PM until nine thirty p. M local time.

00:03:54: on one hundred sixty meters opportunities are already significantly reduced in May.

00:04:00: The band is mainly interesting during the late night hours and around-the-morning gray line, especially for well equipped stations with very low noise floors.

00:04:09: Realistically, the best chances are within North America—with occasional short DX openings toward the Caribbean or South America.

00:04:17: Conditions improve somewhat on eighty meters —especially between about five thirty-five a.m.

00:04:22: and six forty-five am—and again from around nine

00:04:25: p.m.,

00:04:26: into the night!

00:04:27: However... For stable and reliable DX work, forty meters remains considerably more attractive.

00:04:33: In this analysis the forty meter band is one of key bands particularly during morning hours toward Pacific, Western North America or possibly Oceania And during evening towards Europe, Caribbean and South America.

00:04:48: Thirty meters deserves special attention around gray line because it suffers less from D-layer absorption and often remains more stable during unsettled geomagnetic conditions than the higher HF bands.

00:05:00: Twenty meters will be the primary daytime DX band throughout the event.

00:05:04: from Dayton there should be good opportunities toward Europe, during the morning hours towards North in South America around midday an afternoon And later toward Pacific.

00:05:14: Seventeen meters could become very attractive whenever MUF Conditions remain supportive especially when twenty meters becomes crowded.

00:05:22: Fifteen meters is certainly possible with a solar flux between one hundred twenty and one-hundred twenty five, but it will also be more sensitive to geomagnetic instability.

00:05:32: The best chances on fifteen meters should occur during the late morning or early afternoon hours.

00:05:38: Twelve in ten meters are best considered bonus bands.

00:05:41: they may open briefly and dramatically particularly through sporadic E activity of strong daytime ionization but they should not be relied upon as primary operating bands during this period.

00:05:52: Based on this assessment, the best DX day within this timeframe is Sunday May seventeenth twenty-twenty six.

00:05:59: The reason isn't a perfect propagation setup But rather slightly improved solar flux forecast while geomagnetic conditions remain roughly comparable.

00:06:09: The best operating window appears to be sunday morning from approximately five thirty-five am to seven o'clock local time on forty and thirty meters, with opportunities toward the Pacific, US West Coast, Caribbean or even Oceania.

00:06:26: The second strong operating window occurs Sunday evening between approximately eight p.m.

00:06:31: to nine-thirty p. m local time especially for forty, thirty and twenty meters towards Europe, Caribbean and South America.

00:06:40: The clear recommendation for practical DX success around Dayton Hamvention is to monitor twenty meters carefully during the daytime, use forty and thirty meters aggressively during gray line periods.

00:06:52: And keep seventeen and fifteen meters available as opportunity bands.

00:06:56: if operators can choose only one single operating window Sunday morning during the grey line is the strongest choice.

00:07:04: it offers the best overall combination of band stability Grey Line enhancement and realistic DX opportunities during this event period.

00:07:15: We come to the twelfth episode of DX Wetter.

00:07:36: This exhibition is a very special episode.

00:07:42: It stands completely in

00:07:53: the form of The Datenham Vengeance, from May the fifteenth to mid-seventeenth we look at one of the largest, most traditional and most significant amateurs meeting in the world.

00:08:36: For countless amateurs it's far more than just a fair.

00:08:43: It's an appointment point for friendships, technical enthusiasm, innovation international community and true passion for our unique hobby field.

00:08:56: That is why we would like to warmly greet today, especially our American amateur radio friend.

00:09:02: We congratulate you on this great event!

00:09:07: And thank us that the Worldwide Amateur Community has been associated with this extraordinary event since decades ago.

00:09:17: Data is a dream for many amateurs all over the world.

00:09:20: A goal and a symbol of how lively Amateur Funk still exists today.

00:09:28: No matter if you are on site, go through the halls, discover new technologies, meet old friends or just enjoy the unique atmosphere.

00:09:37: We wish you all a fantastic Hemvention in the year of two thousand and twenty-six with many exciting conversations, new contacts and of course great DX connections.

00:09:49: And we also have a small personal favor for you!

00:09:53: If you like DX weather then please tell your amateur radio friend about it and continue to link him on our podcast.

00:10:02: Especially in the International Amateur Fund community, our hobby of mutual exchange lives.

00:10:10: From sharing experiences and from joint enthusiasm moments on the banks.

00:10:17: Thank you very much for listening to us!

00:10:18: And now let's start together in the DX week around the Dayton Ham Mansion of year two thousand twenty-six.

00:10:27: The location for this analysis is the Green County Fairgrounds and Expo Center in Xenia, Ohio.

00:10:34: So it's the location of the Dayton Ham Mansion from May the fifteenth to seventeenth.

00:10:41: The local time zone is Eastern Daylight Time.

00:10:46: Researching prognosis values show a solar flux of one hundred twenty on Friday One hundred twenty on Saturday and one hundred twenty-five on Sunday.

00:10:58: The Planetary A Index is prognosed at twenty five, twenty two and twenty five.

00:11:07: The largest daily Kp value each by five.

00:11:09: This means that solar basic supply can be needed but the geomagnetic system can become significantly restless.

00:11:20: Exactly that's why this DX week is not just a classic nice weather week on Kurzwelle, but also a week for attentive operators who use the calm phases.

00:11:31: For ten years the sun rises on Friday at about six o'clock twenty-one, Saturday at six thirty and Sunday at six nineteen local time.

00:11:46: The morning gray line runs roughly from five o'clock thirty-five to seven o' clock.

00:11:52: The sunset is on Friday at about twenty three and forty, Saturday twenty four and Sunday twenty fifteen.

00:12:03: The evening gray line is between twenty one and twenty thirty local time.

00:12:11: At a distance of about one hundred and sixty meters, the chances in May have already been significantly reduced.

00:12:18: The band is only at night and around the Morgan Gray Line interesting especially for very well equipped stations with low traffic jams.

00:12:29: Realistically they are North America and luckily short DX windows towards Caribbean or South America.

00:12:36: It looks a bit better at about eighty meters, especially between five o'clock thirty-five and six o' clock forty-five.

00:12:45: As well as from twenty one to the night.

00:12:50: But for stable DX connections it remains forty meters much more interesting.

00:12:55: The forty meter band is in this analysis of one of the most important bands particularly towards the Pacific tomorrow West of North America and possibly Oceania, as well as in the evening towards Europe, Caribbean and South America.

00:13:13: Thirty meters around the grey line is very strong to pay attention because it suffers less under D-layer damping and often looks more stable with unstable geomagnetic than the high banders.

00:13:26: Twenty meters above day and up until night the central DX band.

00:13:32: From date out, there are good opportunities in the morning to Europe.

00:13:37: In the afternoon and afternoon towards North America and South America.

00:13:41: Later also towards Pacific.

00:13:44: The useable MUF can be very attractive at seventeen meters, especially if it is over twenty meters.

00:13:52: Fifteen meters is basically possible with a solar flux of one hundred twenty up to one hundred and twenty-five but more sensitive to geomagnetic unrest.

00:14:03: The best chances are here at the late afternoon and early afternoon.

00:14:08: Twelve and ten meters are bonus bands.

00:14:12: They can open short and spectacularly, especially via sporadic E or with good day.

00:14:19: ionization should not be planned as main banders.

00:14:23: The best Dx-Tag within this time frame is after this assessment Sunday, May.

00:14:29: the seventeenth of May two thousand and twenty six.

00:14:32: The reason isn't a perfect value but the slightly better solar flux prognosis with further similar geomagnetic load.

00:14:42: The best time window is tomorrow on Sunday from about five o'clock thirty-five to seven o' clock.

00:14:49: five local time at forty and thirty meters with a chance towards the Pacific, west coast, Caribbean and luckily towards Oceania.

00:15:01: The second strong window is on Sunday evening from about twenty o'clock to thirty-one o' clock local time then especially at forty, thirty and twenty meters towards Europe, Caribbean or South America.

00:15:18: The clear recommendation For secure and practical DX success, look around the Dayton Ham Vansion for at least twenty metres per day.

00:15:27: Use forty and thirty metres consistently in your grey line and keep seventy and fifteen metres open as a chance bander.

00:15:36: If you can only choose one time window, it should be active on Sunday morning to tomorrow's greyline.

00:15:44: This is the best combination of band stability, win grey lines und realistischen DX-Chancen für diesen Zeitraum.

00:15:54: I wish you strong signals and good Dx and see

00:16:30: you

00:16:30: next time!
