JAPAN TO EASTERN U.S. PROPAGATION?
|
What time of day, in UTC/Zulu/GMT time, and on which bands do Japanese stations most often hear eastern U.S. stations at this point in solar cycle 25? I am located in Grid EM95iv in northwestern North Carolina in the foothills of the Blue Ridge Mountains, part of the Appalachian mountain chain, and am using a 130 feet (39.63 meters) length doublet antenna sometimes called a antenna being fed with 300 ohm open wire feeder line or ladder line if you will that then uses a 4 to 1 Balun Designs model 4115t 5 kilowatts rated current balun to a short piece of about 35 feet (10.67 meters) of RG-213 coaxial cable going to my Palstar AT1500CV manual roller inductor antenna tuner or I use a I have up on a 30 feet (9.14 meters) long telescoping pole for my only antennas. The Solarcon A-99 vertical is also called a Antron 99 and was an old 11 meter (CB radio) antenna that works great on the 6 through 17 meter bands. I hear DX most of the time better using it than I do on the doublet horizontally mounted wire antenna. It does not work on 20 meters, although it will tune on 20 meters the Solarcon A-99 vertical antenna pretty much goes deaf once I tune below 18.068 Mhz. I have worked a lot of DX using that antenna, especially on the 17, 15, 12, and 10 meter bands, but I think my elevation on this small mountain named Bald Mountain, (), I live on helps me tremendously. My QTH is at 1,434 feet ASL = 437 meters ASL.?

开云体育Cliff-san,Gud to CU here on A1CLUB reflector. I usually QRV around 21:00Z-24:00Z (6-9AM JST) on 17/15/10m bands and am having big fun of reg chews with my friends in the US. I always login A1-Chat and SKCC SkedPage to find some to QSO. Please have a look at my QRZ.com page which tells my radio systems a bit. HPE to CU SN! 73, // HIRO, JJ1FXF _ |

Hello Cliff,
Looking to the present propagation forecast using it really seems much harder from your QTH to get to Japan than it is from mine (Grid JN48nr). But, taking into account your antenna situation, I would estimate that you have the highest probability for a QSO on 17m and 15m between 20:00 UTC and 03:00 UTC. This is (very) early in the morning until noon in Japan -- so it might be possible especially on weekends. (The 20m band would be the best for QSOs from your location to Japan) It may help to announce your activity ("QRV INFO") here on the list and to spot yourself on clusters (with note: "CW CQ JA").

Cliff,
John makes a good point. In April 2023 (from your QTH to the center of Japan) the peaks for Long Path propagation according to Voacap on the 10 mtr band are at 2300Z (and -- perhaps -- I am not sure about that at 1300Z). There is a much smaller (about 4 S-units lower) peak for Short Path propagation around 2200Z. To check, if I may be received in Japan, I always use and search for my own call sign. If you own an Android phone, you may consider to install "hamalert" and filter for spots of hams from Japan in your region. (On the station's PC, I use DXLabSuite's "SpotCollector", which allows for even more filtering) CU 73 Tom DF7TV |

Thanks honorable gentlemen for all of the great replies to my question and the information all of you have provided to me! I appreciate it very much and hope I can make many more JA QSOs as well as hopefully get to check in on the net which I've never been successful at doing since my initial club membership. Again, thanks very much!?
Very 73!
