Please Spread The Word! Purpose : This contest is intended to test the viability of DominoEX as a digital contest mode, since it compares favourably to RTTY and may better under certain conditions. Digital mode experimenters and RTTY contesters are encouraged to particpate and provide feedback. A prefix related contest has been chosen so that people within the same country can work eachother as well as encourage DX contacts. (see scoring , below).
Contest Name: " DominoEX Prefix Contest". Suggested Contest Call: "CQ DominoEx Contest" or "CQ DPC" Date: July 15, 2006 Time: 0000 UTC to 1800 UTC Bands: 160,80,40,20,15, 10. Mode : DominoEX only DominoEx is developed by Wassilieff ZL2AFP and Murray Greenman ZL1BPU DominoEx has a variety of baud rates that can be used. Entrants are encouraged to read the techical details of each baud rate via http://www.qsl.net/zl1bpu/DOMINO/Index.htm The baud rates are fast enough for contesting yet do not occupy a large bandwidth . The lower baud rates are more effective, generally, for lower bands such as 80 Meters. Contest entrants are free to choose any of the available baud rates but 11 baud is suggested as a standard . Examples of baud rate characteristics: DominoEx 5 occipies 244 Hz and transmist charecters at 35 WPM. DominoEX 11 occupies approximately 262 Hz of bandwdth and transmits at 70WPM. DominoEX 16 occupies approximately 355 Hz of bandwdth and transmits at 100 WPM. DominoEx 22 will oocupy 524 Hz and can transmit at 140WPM. DominEx 8 is 346 bandwidth and will do 50 WPM.. According to ZL1BPU, "...8 baud is wider than 11 baud because it uses double spacing in order to combat ionospheric Doppler, which becomes quite a problem with narrow signals. Depending on conditions, you can expect 1Hz per MHz operating frequency of Doppler, so 8 baud on 80m under severe NVIS conditions works well, and significantly better than 11 baud single spaced." This mode may be found in three software applications,: ZL2AFP DominoEX Software ( http://homepages.ihug.co.nz/~coombedn/FILES/DominoEXj.zip) or MULTIPSK (http://f6cte.free.fr/index_anglais.htm ) and possiblly for Linux http://gmfsk.connect.fi/index.html Suggested Frequencies : Please consult your region's band plan for digital modes. Recently reported DominioEx QSOs have been found on 141075.0, 14107.0 , 14080.0, 14077.0 14076.07072.0 3584.0 Please consider joining the following groups for discussion of other suggested frequencies Digitalradio http://groups.yahoo.com/group/digitalradio/ MFSK http://groups.yahoo.com/group/mfsk/ Classification 1. Single Operator Multi Band 2. Single Operator Single Band Use of DX Clusters IS allowed. Please consider using the K3UK DX Cluster during this contest ( telnet://cluster.dynalias.org ) Exchange: RS(T) report plus a progressive contact three-digit serial number starting with 001 for the first contact. Your log MUST show the correct serial number sent and received for each contact. Scoring: To facilitate easy use of contesting sofware, we have chosen a format that is widely supported. This contest will use the same scoring method and rules as the CQ RTTY WPX 2006 contest . CQ WPX Contests are organized by CQ Magazine , a leading amateur radio publication . This contest is NOT a CQ sponsored contest. "QSO Points:1. Contacts between stations on different continents are worth three(3) points on 28, 21, and 14 MHz and six (6) points on 7 and 3.5 MHz.2. Contacts between stations on the same continent but in different countries, and contacts with maritime mobile stations, are worth two (2)points on 28, 21, and 14 MHz and four (4) points on 7 and 3.5 MHz.3. Contacts between stations in the same country are worth one (1)point on 28, 21, and 14 MHz, and two (2) points on 7 and 3.5 MHz.IX. Multiplier: The multiplier is the number of "valid" prefixes worked. A prefix is counted only once regardless of the number of times the same prefix is worked.1. A prefix is the letter/numeral combination which forms the first part of the amateur call. Examples: N8, W8, AB8, DL5, DJ2, HG1, WD200,WF96, 3DAØ, GB75, ZS66, U3, etc. Any difference in the numbering,lettering, or order of same shall constitute a separate prefix. A station operating from a DXCC country different from that indicated by its call-sign is required to sign portable. The portable prefix must be an authorized prefix of the country/call area of operation. In cases of portable operation the portable designator will then become the prefix. Example:AB5KD operating from Wake Island would sign AB5KD/KH9 orAB5KD/NH9. American DX (KL7, KH6, KP2, KH3, etc.) operating with-in the 48 states must sign with a full designator of their choice. KH6XXX operating from Ohio must use an authorized prefix for the U.S. 8th dis-district (W8, K8, etc.). United States portable stations are not permitted to select a portable prefix designation. For example, WS7I/2 is permitted,but WS7I/WY2 or WS7I/KZ2 is not. Portable designators without numbers will be assigned a zero (Ø) after the second letter of the portable designator to form a prefix. Example: N8BJQ/PA would become PAØ.All calls without numbers will be assigned a zero (Ø) after the first two letters to form the prefix. Example: XEFTJW would count as XEØ.Maritime mobile, mobile, /A, /E, /J, /P, or interim license class identifiers do not count as prefixes.2. Special event, commemorative, and other unique prefix stations are encouraged to participate. Prefixes must be assigned by the licensing authority of the country of operation" Scoring: Multiband score = total QSO points from all bands multiplied by the number of different prefixes worked (prefixes are counted only once). Single Band score = total QSO points on the band multiplied by the number of different prefixes worked.-- Log Submission: email to [EMAIL PROTECTED] Usual contest format for logs.
