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 1931 - every Wednesday for over 37 years! We missed only once due to very severe weather) that have been held. The Chapter meets every Wednesday evening on 28.650 MHz (+/- QRM) at 2000 Local Time (Thursday, 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., 643 North 98th Street, #142 Omaha, NE 68114-2332.

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 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. A 10-10 QSO Party brochure is available from the Information Manager or the Contest Manager. A summary of pertinent information for the remaining 2009 contests is as follows:

Recent developments:
" The geomagnetic field was quiet to unsettled on July 15. Solar wind speed ranged between 393 and 504 km/s.
Solar flux measured at 20h UTC on 2.8 GHz was 66.5. The planetary A index was 5 (STAR Ap - based on the mean of three hour interval ap indices: 5.1). Three hour interval K indices: 13212011 (planetary), 23211111 (Boulder).
The background x-ray flux is below the class A1 level.
At midnight the visible solar disk was spotless."
Coronal mass ejections (CMEs):
"July 13-15: No partially or fully Earth directed CMEs were observed in LASCO or STEREO imagery."
Coronal holes:
" A recurrent coronal hole (CH373) in the northern hemisphere will likely rotate into an Earth facing position on July 18-19.
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 poor. Propagation on long distance northeast-southwest paths is poor to fair.
The geomagnetic field is expected to be quiet on July 16-21. Effects from CH374 could cause unsettled and maybe active intervals on July 22.
