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 75,000. 10-10 would welcome your membership in the organization if you have an amateur radio license with 10 meter privileges. The Gateway Chapter
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 2140! - every Wednesday for over 41 years!). We missed only once due to very severe weather. 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. How To Join 10-10 International
Any licensed amateur authorized to operate on the 10 meter band can join 10-10. It is required that you contact ten 10-10 members (on 10 meters), listing their information as noted on the Membership Application form (10-10#, Call Sign, Operator's Name, Contact Date, City and State/Country). US amateurs send their completed Membership Application and required dues payment to the Data Manager, 10-10 International Net, Inc., P.O. Box 2467, Abingdon, VA 24212-2467. DX amateurs should send the application to the DX Call Area Manager, Carol Hugentober, K8DHK, #29588, 4441 Andreas Avenue, Cincinnati, OH 45211-2622, U.S.A. DX amateurs: Please remember that dues must be paid in US dollars and by International Postal Money Order only. The Data Manager will assign you a 10-10 number and send it to you along with your new member package. 10-10 Contests
Each year, 10-10 sponsors (2) CW contests, (2) Digital Contests and (2) phone contests to encourage maximum cordial activity on the 10 meter band. In addition, there is a 10-10 Day 24-hour Sprint. Plus there are two year long contests. A 10-10 QSO Party brochure is available from the Information Manager or the Contest Manager. A summary of pertinent information for the 2010 contests is as follows:

Recent developments:
"Recent activity
The geomagnetic field was very quiet on June 17. Solar wind speed at SOHO ranged between 272 and 357 km/s.
Solar flux measured at 20h UTC on 2.8 GHz was 123.8 (decreasing 1.5 over the last solar rotation). The Potsdam WDC planetary A index was 3 (STAR Ap - based on the mean of three hour interval ap indices: 3.3). Three hour interval K indices: 11110011 (planetary), 12212111 (Boulder).
The background x-ray flux was at the class B6 level.
At midnight UTC the visible solar disk had 9 spotted active regions (in 2K resolution SDO images).
Region 11768 [S12W82] decayed slowly and quietly.
Region 11770 [S14E16] was quiet and stable.
Region 11771 [S13E31] was quiet and stable.
Region 11772 [S20E16] developed slowly and was mostly quiet.
Region 11773 [N03E38] developed slowly and quietly.
Region 11774 [S18E31] was mostly quiet and stable.
Region 11775 [S27E48] developed slowly and has a significant magnetic delta structure in the large penumbral structure. M flares are possible.
Spotted regions not numbered by SWPC:
New region S2485 [S24E28] emerged with penumbra spots.
New region S2486 [N13W13] emerged with a penumbra spot.
"
Coronal mass ejections (CMEs):"
June 15-17: No obviously Earth directed CMEs were observed in LASCO and STEREO imagery.
Coronal Holes: "A northern hemisphere coronal hole (CH573) will be in a potentially geoeffective position on June 17-20."
Propagation & Forecast:
"Long distance low and medium frequency (below 2 MHz) propagation along paths north of due west over high and upper middle latitudes is fair. Propagation on long distance northeast-southwest paths is poor.
The geomagnetic field is expected to be quiet on June 18-20. A high speed stream associated with CH573 could start a disturbance late on June 20. Quiet to active conditions with a chance of minor storm intervals are possible on June 21-24."
IA. Analysis of Solar Active Regions and Activity from 16/2100Z to
17/2100Z: Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C1 event observed at
17/0812Z from Region 1772 (S20E15). There are currently 7 numbered
sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is likely to be low with a
slight chance for an M-class flare on days one, two, and three (18 Jun,
19 Jun, 20 Jun).
IIA. Geophysical Activity Summary 16/2100Z to 17/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed,
as measured by the ACE spacecraft, reached a peak speed of 360 km/s at
17/0427Z. Total IMF reached 6 nT at 16/2110Z. The maximum southward
component of Bz reached -4 nT at 16/2308Z. Electrons greater than 2 MeV
at geosynchronous orbit reached a peak level of 505 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one, two, and three (18 Jun, 19 Jun, 20
Jun).
III. Event probabilities 18 Jun-20 Jun
Class M 20/20/20
Class X 05/05/05
