The February 2006 Digital On Six "Dead-Band" Contest
Purpose: 1) To provide a spirited competition
during dead band conditions 2) To rekindle interest
in SSB Meteor
Scatter contacts 3) Provide activity periods for new stations to
learn and demonstrate proficiency using High Speed
Meteor Scatter. i.e. WSJT modes FSK441A & JT6M
00:00 UTC Feb 4 - Feb 6 03:00 |
This contest is designed for week-ends during February and operators should easily find some time to invest in this event. | ||||||||||
Exchange |
Exchange is both callsigns, 4 character maidenhead grid squares, and final `Rogers'. | ||||||||||
Propagation Modes |

General Rules |
Note: If there are band openings during the contest times, enjoy the openings but for the contest log only meteor scatter contacts count for credit. |
||||||||||
Multipliers |
Each Random contact counts as 1
multiplier.(If no random contacts are made, the default
multiplier is "one". QSO Points
|
||||||||||
Scoring |
QSO points (calculated as
above) x Multipliers Note For
Rovers: QSO points x (No. of random meteor
scatter contacts completed + Number of grids from which
at least 1 QSO was completed). Rovers compete with fixed
stations. Rovers who also operate from the "Home QTH"
plus "Rover Locations" should total two log
sheets and total score is equal to the sum of both logs. |

Users Research Information:
Because High Speed Meteor Scatter with WSJT is relatively new to
most of the Six Club Members and SSB meteor
scatter contacts are seldom being attempted the following

SSB METEOR
SCATTER PROCEDURES FOR REGION 2:
SSB exchange requirements and procedures are the same as HSMS
procedures, with the following changes:
1. The period is normally 15 seconds, with the Western station
again calling first at the start of each minute.
2. Random MS operation does not necessarily follow an exact
sequence. Break-in is commonly used.
3. Information exchange (report) is usually the burst-length
"S" report (S1 through S5) on schedules, Grid Squares
on
random contacts. For random contacts, yet other exchanges are
sometimes heard.
4. Phonetics must be used for random operation; they should not
be used for schedules.
5. For CQs, the usual SSB calling frequencies are usually used
during periods of low activity. However, during the peaks
of major showers, they quickly become overcrowded. Frequencies
every 5 kHz above and below the calling frequencies
are then commonly used.
6. On SSB, attempts are usually made to complete the entire QSO
on a single long burst. Thus, break-in procedures
should be used whenever possible.

Random Hour Message Copied from:
http://www.ykc.com/wa5ufh/WSJTGROUP/randomhour.htm
The message formats described in this manual are for Random
Hour and recommended for all other times when
calling cq on the call frequency .This discussion should not be
confused with the Standard Operating
Procedures used for Meteor Scatter Schedules. i.e Skeds made on
Ping Jockey.
Note: Standard SH messages are better not used on the Call
Frequencies. The following messages
only cause confusion when used on shared frequencies.
RRR
R26 or R27
73
Note: If you are using a call frequency and the person you are in
contact with starts sending Sh messages,
don't change to match him! Keep using the Modified Random Hour
messages and he will probably swap to
the correct format. (be a good elmer, email him the correct
procdure)
Modified Messages:
WA5UFH who is Working W5SNX on a designated call frequency:
Message 1: W5SNX DE WA5UFH <
Message 2: W5SNX 27 WA5UFH 2727 <
Message 3 SNX R27 <
Message 4: SNX RRR <
Message 5: SNX 73 <
Note Message 1: The WSJTGROUP recommends adding the
DE between both calls on six meters.
(the DE is optional for two meters because of almost always
shorter ping widths) The use of "DE" helps
others who receive Both Calls to determine who the transmitting
station is. Message #2, no change is
necessary. Messages 3, 4 & 5 are appended with the suffix of
the station you are working by inserting
that suffix ahead of the text. All messages are appended On
The Fly as the contact progresses.
Note: To append the message text click in front of the Sh message
using the mouse and insert the
text to be added. Separate with a single space the text added and
the Sh Message text.

The OffSet
Method Explained
Assuming W1AW is calling CQ
on six meters 50.260MHz during Random Hour
1.
CQ U7 W1AW (Up 7KHz from calling frequency) W1AW will listen on
50.267 MHz and swap their Tx Frequency from
50.260 MHz to 50.267 MHz after receiving a call.
2. CQ D7 W1AW (Down 7KHz from calling frequency) W1AW will
listen on 50.253 and swap their Tx Frequency
from 50.260 MHz to 50.253 MHz upon receiving a call)
3. CQ F W1AW (Up 6 KHz from calling frequency) W1AW will
listen on 50.266 and swap
their Tx Frequency from 50.260 MHz to 50.266 MHz upon
receiving a call)
4. CQ 267 W1AW (Listening on 50.277) W1AW will switch from
50.260 MHz to 50.267MHz after receiving a call.
Note: For method #3 above, the letter indicates the number of
kHz higher than the CQ frequency the calling station is listening.
CQC - Up 3 kHz
CQE - Up 5 kHz
CQZ - Up 26 kHz
CQAA - Up 27 kHz. Etc
Assuming
W1AW is calling using the OffSet Method during Random Hour on 144.140MHz
1. CQ U7 W1AW (Up 7KHz from calling frequency) W1AW will listen
on 144.147 MHz and swap their Tx Frequency from
144.140 MHz to 144.147 MHz after receiving a call.
2. CQ D10 W1AW (Down10KHz from calling frequency) W1AW will
listen on 144.130 and swap their Tx Frequency
from 144.140 MHz to 144.130 MHz upon receiving a call)
3. CQ F W1AW (Up 6 KHz from calling frequency) W1AW will
listen on 144.146 and swap
their Tx Frequency from 144.140 MHz to 5144.146 MHz upon
receiving a call)
4. CQ 147 W1AW (Listening on 144.147MHz) W1AW will switch
from 144.140 MHz to 144.147 MHz after receiving a call.
Dimension 4:
This application sets your computer to the correct time. This is
absolutely necessary for all WSJT modes.
This might seem like a strange place to start your WSJT
Experience, just trust us. (Get this working first them proceed)
Note: An alternative to Dimension 4 is NMEATime. You might
consider this if you plan to use a GPS i.e. portable. (Most
stations are using D4)
How to set-up Dimension 4:
Settings:
Server: tick.usno.navy.mil
Check: Load Dimension 4 at startup
Once loaded, wait until online
