Saturday – September 10, 2011

This contest is held concurrently with the ARRL September VHF QSO Party, with compatible rules and operating procedures. The purpose of this contest is to:

  • Promote the use of FM VHF/UHF simplex
  • Provide an opportunity for radio amateurs to test the limits of their stations using FM VHF/UHF and to experiment with ways to improve their stations
  • Practice deploying portable and mobile operation as a means of identifying effective locations for temporary relay stations
  • Provide a simple and enjoyable radio contest experience (“Have fun!”)


 Saturday, Sept 10, 2011; 1200 to 1700 Mountain Time (1800 to 2300 UTC)


To work as many stations as possible using FM simplex on the 146 MHz, 222 MHz and 440 MHz bands in as many different VHF grids as possible.

(Consistent with the ARRL Rules, 146.52 MHz is not allowed to be used in the contest.)

Suggested Frequencies:

2 Meters: 146.58, 146.55

222 MHz: 223.5 MHz

440 MHz: 446.0, 446.100 MHz

Entry Categories:

The following entry categories are available for this contest, consistent with the entry categories for the ARRL September VHF QSO Party. All categories (excluding Single Operator Portable) operate within these power limits: (146 MHz–200 W PEP, 222 MHz 100 W PEP, 440 MHz 100 W PEP).

Single Operator – same as Single Operator Low Power in the ARRL rules

Single Operator Portable – power limit of 10 W PEP, operating from a fixed location using a portable power source, portable equipment and antennas

Rover – operates from 2 or more grid squares with 1 or 2 operators, same definition as Limited Rover in the ARRL rules. Rovers must sign “Rover” after their callsign.

Multioperator – operates with more than with operator from a fixed location


QSO Points: Count one point for each 146 MHz QSO and two points for each 222 MHz and 440 MHz QSO.

Multiplier: The total number of different grid squares worked per band. Each grid counts as one multiplier on each band it is worked.

Final score: Multiply the total number of QSO points from all bands operated by the total number of multipliers for final score. 

Rovers only: The final score consists of the total number of QSO points from all bands times the sum of unique multipliers (grid squares) worked per band (regardless of which grid square they were made in) plus one additional multiplier for every grid square from which they successfully completed a contact.                         


1.  Use only one call sign per entry per station, except family members who share a station.

2.  A rover station may use only one call sign.

Grid Locator Information:

Grids are 2° longitude x 1° latitude squares designated with 2-letters and 2-numbers, such as DM78. To determine which grid you are operating from, refer to this web page: or use a GPS receiver that displays the location in Maidenhead (vhf grid) format.

Here are some general guidelines that may help in case you work someone who does not know their grid square:

  • Greater Denver is in grid DM79
  • Boulder is split between grids DM79 and DN70, so check the location carefully.
  • Colorado Springs and Pueblo are in grid DM78
  • Fort Collins, Loveland and Longmont are in grid DN70.
