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 2085! - every Wednesday for over 40 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:
"The geomagnetic field was quiet to unsettled on May 25. Solar wind speed at SOHO ranged between 434 and 540 km/s, weakly under the influence of a high speed stream from CH518.
Solar flux measured at 20h UTC on 2.8 GHz was 117.2 (decreasing 3.9 over the last solar rotation). The Potsdam WDC planetary A index was 7 (STAR Ap - based on the mean of three hour interval ap indices: 7.3). Three hour interval K indices: 22132221 (planetary), 22122321 (Boulder).
The background x-ray flux is at the class B4 level.
At midnight UTC the visible solar disk had 13 spotted active regions (in 2K resolution SDO images).
Region 11484 [N12W81] rotated quietly to the northwest limb.
Region 11486 [N17W25] was quiet and stable.
Region 11488 [N11E15] was quiet and stable.
Region 11489 [S27E22] was quiet and stable.
Region 11490 [S12E46] developed slowly and quietly.
New region 11491 [N23W28] emerged on May 23 and was noticed 2 days later by SWPC.
New region 11492 [S13E71] rotated partly into view at the southeast limb on May 24 and was numbered the next day by SWPC. There's some polarity intermixing and a possible magnetic delta structure in one of the leading peumbrae. The region could produce a minor M class flare.
Spotted active regions not numbered by NOAA/SWPC:
S1671 [S21E03] was quiet and stable.
S1673 [N26W70] was quiet and stable.
New region S1682 [S22E72] rotated into view at the southeast limb.
New region S1683 [N01E30] emerged with one spot on each side of the equator.
New region S1684 [N17E19] emerged with a few tiny spots.
New region S1685 [S12W17] emerged on the east side of CH519.
"
Coronal Mass Ejections (CMEs):"
May 23-25: No obviously Earth directed CMEs were observed in LASCO or STEREO imagery. "
Coronal Holes: "A poorly defined southern hemisphere coronal hole (CH519) was Earth facing on May 23-24.
"
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.
The geomagnetic field is expected to be quiet to unsettled on May 26-28 due to weak effects from CH519, occasional active intervals are possible.
NOAA Solar Report (Prepared jointly by the U.S. Dept of Commerce, NOAA, Space Weather Prediction Center and the U.S. Air Force on a daily basis):
Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 127 Issued at 2200Z on 06 May 2012
IA. Analysis of Solar Active Regions and Activity from 24/2100Z
to 25/2100Z: Solar activity was low. A few nominal C-class flares
occurred. Two new active Regions, 1491 (N23W29) and 1492 (S13E65)
were numbered today. A few CMEs were observed during the period,
but all appear to be limb events and non-geoeffective.
IB. Solar Activity Forecast: Solar activity is expected to be very
low to low for the next 3 days (26-28 May).
IIA. Geophysical Activity Summary 24/2100Z to 25/2100Z:
The geomagnetic field was quiet. The greater than 2 MeV electron flux
at geosynchronous orbit reached high levels during the period.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be quiet to unsettled on day 1 (26 May) due to a CME
from 22 May. Mostly quiet conditions are expected on days 2-3 (27-28
May).
III. Event Probabilities 26 May-28 May
