Important Note: Paper logs are no longer accepted, see Section XII.
27 hours for all stations, all categories. Operate any portion of the contest period you wish. (Note: Exception for QRP Hilltopper.)
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.
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. Note exceptions in Rule XI for common repeater frequencies and 146.52 MHz.
The use of any technology or other source that provides callsign or multiplier identification along with frequency information about a signal to the operator. This includes, but is not limited to, use of DX Cluster, packet, local or remote callsign and frequency decoding technology (e.g., CW Skimmer or Reverse Beacon Network), or operating arrangements involving other individuals.
For all categories (except Rover): Transmitters and receivers must be located within a 500-meter diameter circle or within the property limits of the station licensee's address, whichever is greater.
Stations in any category, except Rover and QRP Hilltopper, may operate from any single location, home or portable.
Callsign and Maidenhead grid locator (4 characters, e.g., EM15). Signal reports are not required and should not be included in the log entry.
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 himself or herself in a new grid locator location. Such change in location must be clearly indicated in the rover's log.
One (1) point per QSO on 50 MHz and two (2) points per QSO on 144 MHz. Allowed modes are "PH" (SSB, AM, FM), "CW" and "DG" ('digital' modes such as FT8, FT4 and MSK144). Entrants are requested to stop using “RY” or “PH” for QSOs made using “digital” modes. Work stations once per band, regardless of mode. 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. W9FS/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
W9FS/R has 230 QSO points (50 + 80 + 60 + 40) x 70 multipliers (25 + 10 + 30 + 5) = 16,100 total points
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://www.cqww-vhf.com/plaques.htm >.
The club score is the total aggregate score from logs submitted by members. There are two separate club competition categories.
General club rules:
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.
Making or soliciting QSOs on the national simplex frequency, 146.52 MHz, or your country's designated national simplex frequency, or immediately adjacent guard frequencies, is prohibited. Use of commonly recognized repeater frequencies is prohibited. Recognized FM simplex frequencies such as 146.49, .55, and .58, and local-option simplex channels may be used for contest purposes.
Aeronautical mobile contacts do not count.
Contestants should respect use of the DX window, 50.100-50.125 MHz, for intercontinental QSOs only.
UTC is the required logging time.
Log entries must be submitted by July 28, 2021 to be eligible for awards.
An extension may be requested by e-mail to < firstname.lastname@example.org >. The request must state a legitimate reason and must be received before the log deadline. Extensions are granted only upon confirmation by the Contest Director.
Logs submitted after the deadline may be listed in the results, but are not eligible for awards.
The CABRILLO file format is the standard for logs. See <https://cqww-vhf.com/cabrillo.htm> for detailed instructions on filling out the CABRILLO file header. Note: U.S. stations must indicate the station location in the CABRILLO header (e.g., LOCATION: OH).
Web upload of Cabrillo log files is the only method of log submission. Web upload is available at <https://cqww-vhf.com/logcheck/>.
An ADIF Converter is provided for convenience and, at present, is suitable only for FIXED station logs (sorry Rovers). It is available at <https://cqww-vhf.com/adif/>.
Entry Confirmation: All logs received will be confirmed via email. A listing of logs received can be viewed at < https://cqww-vhf.com/logs_received.htm>.
Your submission of a log entry affirms that: (1) you have abided by all the rules of the contest as well as those of your country's licensing authority; (2) you accept any decisions made regarding your entry by the contest's adjudication process which are official and final.
