I. OBJECTIVE
The objectives of this contest are for amateurs around the world to contact as many amateurs as
possible in the contest period, to promote VHF, to allow VHF operators the opportunity to experience
the enhanced propagation available at this time of year, and for interested amateurs to collect VHF
Maidenhead grid locators for award credits.
II. BANDS
All amateur radio frequencies on 50 MHz (6 meters) and 144 MHz (2 meters) may be used as authorized
by local law and license class.
III. MODES
Only analog modes (SSB/CW/FM) during the SSB/CW weekend.
Only digital modes (FT4, FT8, MSK144, Q65, etc) during the Digital weekend.
IV. CONTEST EXCHANGE
Callsign and Maidenhead grid locator (4 characters, e.g., EM15). Signal reports are not required
and should not be included in the log entry.
V. MULTIPLIERS
The multiplier is the number of different grid locators worked per band. A grid locator is counted
once per band. Exception: The Rover who moves into a new grid locator may count the same grid locator
more than once per band as long as the Rover is in a new grid locator location.
Such change in location must be clearly indicated in the Rover's log.
- A Rover station becomes a new QSO to the stations working him or her when that rover changes grid locator.
- The grid locator is the four-character Maidenhead grid (e.g. EM15).
VI. SCORING
One (1) point per QSO on 50 MHz and two (2) points per QSO on 144 MHz. Work stations once per band.
Multiply total QSO points times total number of grid locators (GL) worked.
Rovers: For each new grid locator visited, contacts and grid locators count as new. Final Rover score
is the sum of contact points made from each grid locator times the sum of all grid locators worked
from all grids visited.
Example 1. K1GX works stations as follows:
50 QSOs (50 x 1 = 50) and 25 GLs (25 multipliers) on 50 MHz
35 QSOs (35 x 2 = 70) and 8 GLs (8 multipliers) on 144 MHz
K1GX has 120 QSO points (50 + 70 = 120) x 33 multipliers
(25 + 8 = 33) = 3,960 total points.
Example 2. AC0RA/R works stations as follows:
From EN52: 50 QSOs (50 x 1 = 50) and 25 GLs (25 multipliers) on 50 MHz
From EN52: 40 QSOs (40 x 2 = 80) and 10 GLs (10 multipliers) on 144 MHz
From EN51: 60 QSOs (60 x 1 = 60) and 30 GLs (30 multipliers) on 50 MHz
From EN51: 20 QSOs (20 x 2 = 40) and 5 GLs (5 multipliers) on 144 MHz
AC0RA/R has 230 QSO points (50 + 80 + 60 + 40) x 70 multipliers
(25 + 10 + 30 + 5) = 16,100 total point
VII. ENTRY CATEGORIES
For all categories (except Rover): Transmitters and receivers must be located within a 500-meter
diameter circle. Antennas must be physically connected by RF transmission lines to the transmitters
and receivers. Stations in any category, except Rover, shall operate from a
single location, home or portable.
- Single Operator: Only one signal allowed at any one time; the operator may change bands at any time.
- High Power (All Band or Single Band): Total output power must not exceed 1500 watts.
- Low Power (All Band or Single Band): Total output power must not exceed 100 watts.
- QRP (All Band or Single Band): Total output power must not exceed 10 watts.
- Hilltopper: This is a single-op portable category for an all-band entry limited in time to a
maximum of 6 continuous hours. Backpackers and portables who do not want to devote resources and time
to the full contest period are encouraged to participate, especially to activate rare grids. Any
power source is acceptable. Total output power must not exceed 100 watts.
- Rover: A Rover station is one manned by no more than two operators, travels to more than one
grid location, and signs "Rover" or "/R" with no more than one callsign.
- Multi-Op. A multi-op station is one with two or more operators and may operate 6 and 2 meters
simultaneously with only one signal per band.
VI. ASSISTANCE
- All entrants, regardless of category, are permitted to use spotting assistance or nets including
but not limited to DX-alerting nets, internet chat rooms, APRS and other packet, reverse beacon networks
and repeaters to identify stations available for contacts and to announce their availability for contacts.
- Such assistance may NOT be used to convey receipt or non-receipt of any required element of a
contact or to request a repeat of any required element of a contact during a QSO. It is acceptable to
use assistance to let your QSO partner that you have successfully received all required information to
complete a valid QSO (eg: Telling a partner in an MSK144 QSO that you have received his RRR or RR73 transmission).
- Rovers may use APRS or other assistance methods to announce their location and frequency.
IX. AWARDS
Electronic certificates will be made available for download for everyone that submits an entry.
Plaques will be awarded to the highest scoring stations where sponsored. They are offered in various
categories on a sponsored basis. Clubs and individual plaque donors are sought and may find information
on how to sponsor a CQWW VHF Contest plaque at
<https://cqww-vhf.com/plaques.htm>.
X. CLUB COMPETITION
The club score is the total aggregate score from logs submitted by members. There are two separate club
competition categories.
- USA Clubs: Participation is limited to club members residing within a 250 mile radius circle from
the center of club area.
- DX Clubs: Participation is limited to club members residing within EITHER the DXCC country where
the club is located OR within a 400 km radius circle from the center of club.
The word “reside” shall be defined as: To dwell permanently or continuously or to occupy a place as a
person's fixed, permanent, and principal home for legal purposes.
General club rules:
- National organizations (e.g., JARL, REF or DARC) are not eligible for the club competition.
- Spell out the full name of the club. See examples of active club names at
<https://cqww-vhf.com/clubnames.htm>.
- Single-operator entries may only contribute to one club. Multi-operator scores may be allocated
to multiple clubs as a percentage of the number of club members participating in the operation. The log
entry must spell out the full club name (and club allocations if multi-op).
- A minimum of three logs must be received for a club to be listed in the results. Checklog entries
are not counted for the club score.
XI. MISCELLANEOUS
- An operator may sign only one callsign during the contest. This means that an operator cannot generate
QSOs by first signing his callsign, then signing his daughter's callsign, even though both callsigns are
assigned to the same location.
- A station located exactly on a dividing line of a grid locator must choose only one grid locator from
which to operate for exchange purposes.
- A different multiplier cannot be given out without moving the complete station at least 100 meters.
- Use of commonly recognized repeater frequencies is prohibited. Recognized FM simplex frequencies such as 146.49, .52,
.55, and .58, and local-option simplex channels may be used for contest purposes.
- Repeater and satellite QSOs are not valid for contest credit.
- Aeronautical mobile contacts do not count.
- UTC is the required logging time.
