Of course, the problem with Winlink is that since Winlink stations do 
not, as a matter of policy, listen before transmitting, there is a grave 
risk that a Winlink station will interfere with other emergency 
traffic.  Other forms of emergency communication (the main ones, i.e.

[digitalradio] Digital mode contest : North American High Speed Meteor Scatter 2007 Gemenids Test

2007-12-14 Thread Andrew O'Brien
North American High Speed Meteor Scatter
2007 Gemenids Test



Sponsor: WSJT Group  groups.yahoo.com/group/wsjtgroup/

Contest period:  UTC Dec 13 to 0200 UTC Dec 17, 2007. The test
period has been chosen to coincide with the Geminids meteor shower.
More information on this shower can be found here.

Bands: 50, 144, 222, and 432 MHz.

Rules and scoring: QSOs can be made using any mode provided they are
entirely by meteor scatter. No QSOs within own maidenhead grid square
or any of the 8 adjacent grid squares. Exchange is both callsigns, 4
character maidenhead grid squares, and final `Rogers'. Output power up
to the legal limit on any band. Use of self-spotting and scheduling
(eg. Pingjockey website) before and during the event are allowed.
Random QSOs completed without the use of any scheduling aids or
self-spotting will score double points. Detailed procedures for random
operation can be found here. All operators are reminded that
exchanging information without the use of meteor scatter during the
QSO attempt invalidates the contact. The scoring is as follows:

BandPoints  Random Points
50  1   2
144 2   4
222 4   8
432 8   16

Total score is QSO points times number of unique grid squares worked
per band (standard VHF contest scoring).

An operator is free to attempt both scheduled and random QSOs. If a
random QSO is made with a station that has already been worked with a
schedule, replace with appropriate random points. Example: K1JT works
W8WN on 50 MHz after scheduling on Pingjockey. The QSO is scored with
1 point. Later in the event, these stations work randomly. The QSO is
now scored with 2 points. An example of self-spotting is a Pingjockey
post `CQ east on 144.140'. QSOs that result from making or reading
such a posting cannot be scored as random. Monitoring Pingjockey
activity violates the spirit of random operation.

Rovers: QSO points x (Unique grid squares worked per band + Number of
grids from which at least 1 QSO was completed). This is the standard
rover scoring formula for VHF contests. Rovers making QSOs from their
home station must submit a separate log for those contacts.

Awards: Certificates will be mailed to the high scorers in each of the
four North American time zones. Awards will also be given to top
scoring Random-Only operators and Rovers in each time zone. A
Random-Only operator is expected to refrain from any self-spotting
and/or scheduling before and during the contest.

Log submission: Participants should submit: 1) A summary and 2) A log.

1) The summary should include: i) Your call; ii) Your time zone; iii)
Category: Regular, Random-Only, or Rover; iv) QSOs per band; and vi)
Final claimed score. Please show the arithmetic you use to obtain your
final score, ie. QSO points x Multipliers = Final Score.

2) For each QSO, the log must show: i) Date, ii) Time (UTC), iii)
Callsign of station worked, iv) Grid, v) Band (50, 144, etc), and vi)
QSO points. This information will be used to cross-check with other
logs for scoring accuracy.

Submission of the log as an Excel spreadsheet (arrange the columns as
shown above) is strongly encouraged, although any convenient log
submission format is acceptable. OpenOffice Calc is an excellent free
program that almost perfectly mimics Excel. It can be downloaded here.
Logs should be emailed by January 17, 2008 to Mike WB2FKO
([EMAIL PROTECTED]).

That's an interesting observation.  Maybe you could keep some
statistics on message lengths - it seems like Winlink ought to
have a severe limit on message length.

And then forwarded do-gooder emails are the bane of regular email
as well as radio-forwarded mail.  When I see FW in the subject
like of a message I almost always delete it without reading.
The few exceptions are when the rest of the subject line shows
it is something related to a current topic that I am interested
in.

There is a book United States Army in Vietnam, Military
communications, a test for technology.  It is very dry reading,
being official history, yet it gives some insights into why the
U.S. was losing the war.  There is a passage about someone
sending a message with Operational Immediate precedence, which
means it blocked all messages of lower precedence, and it was
so long it took 8 hours of operator time to punch into tape
before it started transmitting.  Then took several hours to
transmit.

Well, 

Do we really need contests, ragchewing, voice qsos, voice nets, cw
qsos, cw nets,  on HF? Realy it all depends on what each individual
wants to do! Your millage might vary! It's a hobby OM! Each guys
pleasure might be someone else's discomfort, but when an emergency
arises then I think that everyone else's hobby needs must back off for

If you are monitoring a Pactor transmission, or preserving same for archival

My understanding is that all Winlink 2000 transmissions are Pactor ARQ.

Then it was non B2F, and that makes it possible the message was attempted,

Pactor I cannot handle the B2F Compression used within the WinLink 2000

Pactor III and ARQ would take a large capability for processing and a CPU

I am confused. Sholto said it was Pactor 2, not Pactor 3. I don't know
 that Winlink is involved at all. But there is so much mystery about
 these modes, and it seems like an archive would be a good idea.

 I set up one for SSTV but got tired of deleting the unseemly images, but
 others have set up really nice ones.

 My understanding is that all Winlink 2000 transmissions are Pactor ARQ.

 Methinks something stinks here:)

 Could you set up an automatic archive of these PACTOR transmissions,
 like the various ones that exist for SSTV?
