ELEVENTH WA VHF/UHF/SHF
FIELD DAY
Sunday, 30 April 2006.
1. The contest is open to all individual
licensed amateurs. All bands above 50 MHz, and all licensed modes including
digital modes, may be used.
2. Points are scored for two way contacts
between pairs of stations, at least one of which must be in the VK6 call area.
(Contacts via electronic relays other than Amateur satellites do not count
towards the score, but may be used for liaison purposes.) For the purposes of
the contest, a portable station is one which is being operated away from the
usual station address and which is not powered from the AC mains. Mobile
stations (including permanently mobile) count as portable.
3. CONTEST TIME: 1030-1500 WST (0230Z-0700Z)
on Sunday, 30th April 2006.
The contest is divided into 2 intervals of
2 hours each, 1030-1230 WST
and 1300-1500 WST. These are separated by
a half hour (1230-1300 WST) for lunch. Two stations may work each other for a
scoring contact once on each band in each 2 hour interval.
4. The contest exchange will consist of a
signal report, 3 digit serial number starting from 001, and the station
location.
5. Each scoring monoband contact is worth
1 point times the following multipliers:
DISTANCE MULTIPLIER:
One point for each 25km or part thereof,
up to a maximum of 15 points.

FIXED STATION TO FIXED STATION MULTIPLIER:

PORTABLE TO METROPOLITAN FIXED STATION
MULTIPLIER: 2
PORTABLE TO COUNTRY FIXED STATION
MULTIPLIER: 4
PORTABLE TO PORTABLE MULTIPLIER: 4
That is, contacts count double if one of
the stations is portable, and quadruple if both stations are portable, or if
one is portable and the other is a country fixed station.
A country station is one which is at least
100km from GPO Perth.
FOUNDATION LICENCE MULTIPLIER: 4
Contacts in which one or both stations is
a Foundation Licence station count quadruple. The other multipliers still
apply.
6. SECTIONS: There are four separate
sections in the contest:
1.
Portable;
2. Fixed;
3. Foundation
Licence Portable;
4. Foundation Licence Fixed.
7. GROUP OPERATION: There is no section
for club stations, but contacts with club stations count towards the scores of
individual amateurs entering sections 1 to 4. Groups of up to 3 licensed
amateurs may pool their equipment, and operate from a single portable site
under their own individual call signs. (An exception is made for VK6WH, which
is allowed multiple operators, and can enter the portable section even if
operated from Wireless Hill.)
The use of multiple call signs by a single
individual is not allowed.
8. CROSSBAND CONTACTS are permitted, but
only score in special circumstances. If two stations work crossband from band A
to some other band (B, say), but do not have a two way contact on band A
in the relevant 2 hour time period, then once, and only once, in that
period, each may claim towards their score half the points that would
have resulted from a band A contact. This means that if they do not have
a two way contact on band B in the time period, they may also claim (once only)
half the points that would have resulted from a band B contact.
9. SATELLITE CONTACTS. In addition to terrestrial contacts, each
pair of stations is allowed one contact per satellite per 2 hour period,
provided that both stations are in the VK6 call area, and that all uplink and
downlink frequencies used are in the VHF/UHF/SHF Amateur bands. Scoring is
based on the terrestrial distance between the stations, and the
transmitting and receiving bands actually used by the station claiming the
points. If these are bands A and B, then the station may claim half the
points that would result from a band A contact, plus half the
points that would result from a band B contact.
10. LOGS should be sent to:
CONTEST MANAGER, WEST AUSTRALIAN VHF GROUP (INC),
or
by email, to field_day@vhf.wirelessplanet.com.au
Logs
must arrive by 3pm, Monday, 22 May 2006 (May Meeting night).
The Contest Manager's decisions and
interpretation of the rules are final.

REMEMBER: Contacts with portable stations
count more, as do country fixed stations if you are portable. Contacts
involving Foundation licensees count quadruple.
For example, a contact on 2m over a path
length of 130km, is worth 12 points.
However, if one station was portable, and the other was a country fixed
station, then there would be a 4x multiplier (ie, bringing the contact up to 48
points); if one of those stations was
also a Foundation class license, then a further 4x multiplier would apply,
making the contact worth a massive 192 points!
(See section 5 for multiplier details).
