The Gateway Chapter

Who We Are

Ten-Ten International Net, or 10-10 for short, is an organization of amateur radio operators dedicated to maintaining high levels of amateur radio communications on the 10 meter amateur band (28.0-29.7 MHz). Established in 1962, 10-10 has grown continuously since that day, with some ups and downs according to the numbers of sunspots and the openness of the band. As you read this, the number of 10-10 numbers issued to members now exceeds 77,000. 10-10 would welcome your membership in the organization if you have an amateur radio license with 10 meter privileges.

The Gateway Chapter Membership is primarily from the greater St. Louis, MO metroplex. Our Chapter was formed in 1972 by Don Wirth, WB0ECM #3218, and we are very proud of the number of nearly consecutive Net Sessions (Currently 2322 - every Wednesday for over 44 years!). We missed only once due to very severe weather and a widespread power outage. The Chapter meets every Wednesday evening (local Time) on 28.650 MHz (+/- QRM) at 2000 Local Time (Thursday (UTC), 0100Z Summers and 0200Z Winters). We conduct informal, "open" nets and all amateur radio operators are cordially invited to attend for the purpose of exchanging ten-ten numbers and for general rag chewing.

How To Join The Gateway Chapter

Membership in the Gateway Chapter is available to any ham who has a 10-10 number and who resides within ground wave range of the St. Louis area. We also offer a certificate (but not Gateway membership) to other 10-10 members who contact and exchange 10-10 data (10-10#, Call Sign, Operator's Name, Contact Date, City and State/Country) with five (5) Gateway members.
The cost is only $1.00 for a lifetime membership! Send your contact information along with one dollar (non-recurring) to our Certificate Manager, Henry Schaper, KA0AWS, 241 Tapestry Dr., St. Louis, MO 63129 and Henry will send you a handsome non-propagating Gateway Chapter Certificate suitable for framing. A rare bargain indeed!

How To Join 10-10 International

Jan Alvestad's Remarks & Forecast (http://www.solen.info/solar/):

Propagation Forecast
Recent developments: "The geomagnetic field was quiet to minor storm on March 21 under the influence of a high speed stream from CH797. Solar wind speed at SOHO ranged between 335 and 719 km/s. Solar flux at 20h UTC on 2.8 GHz was 71.0 (decreasing 12.2 over the last solar rotation). The average 90 day 10.7 flux at 1 AU was 73.7. The Potsdam WDC planetary A index was 23 (STAR Ap - based on the mean of three hour interval ap indices: 23.4). Three hour interval K indices: 13423554 (planetary), 23433433 (Boulder) The background x-ray flux is at the class A4 level. At the time of counting spots (see image time), spots were observed in 3 active regions using 2K resolution (SN: 35) and in 2 active regions using 1K resolution (SN: 23) SDO images on the visible solar disk. New region 12643 [N08E70] rotated into view on March 20 and was numbered by SWPC the next day. Spotted regions not numbered (or interpreted differently) by SWPC: New region S5629 [N15E29] was observed with a tiny spot in an old plage area. New region S5630 [S04W57] emerged with tiny spots. "
Coronal Mass Ejections (CMEs), "March 19-21: No obviously Earth directed CMEs were observed in available LASCO imagery."
Coronal Holes "A recurrent trans equatorial coronal hole (CH797) was in an Earth facing position on March 18-21. A recurrent trans equatorial extension (CH798) of the southern polar coronal hole will likely rotate across the central meridian on March 24-26.."
Propagation and Forecast: "Long distance low and medium frequency (below 2 MHz) propagation along paths north of due west over upper middle latitudes is poor. Propagation on long distance northeast-southwest paths is poor to fair. Forecast The geomagnetic field is expected to be quiet to minor storm on March 22-23 and quiet to unsettled on March 24 due to effects from CH797."
24 Hour Summary: (Courtesy of www.solarham.net and NASA) "Solar activity was very low. A new spot group rotated onto the visible disk and was assigned as NOAA/SWPC Region 2643 (N09E72, Hrx/alpha), but was inactive. No Earth-directed CMEs were observed in available coronagraph imagery. .Forecast... Solar activity is expected to remain very low with a slight chance for C-class flares all three days (22-24 Mar) due to new Region 2643. [Report of Solar-Geophysical Activity] Mar)."

Solar activity was very low and only low-level background flares were observed this period. Region 2488 (N03E12, Dai/beta) exhibited minor growth but Regions 2486 (S19W09, Hrx/alpha) and 2487 (S12W05, Cao/beta) were in decay. No Earth-directed coronal mass ejections (CMEs) were observed in available coronagraph imagery. .Forecast... Solar activity is expected to be very low with a chance for C-class flares over the next three days (24-26 Jan). From n3kl.org
