A new and exciting operating event will kick off on January 1, 2018, at 0000 UTC (New Year’s Eve in US time zones), when the ARRL International Grid Chase gets under way. The year-long event hopes to build on the success of the highly successful 2016 National Parks on the Air (NPOTA). The objective is to work stations on any band (except 60 meters) in as many different Maidenhead grid squares as possible, and then upload your log data to ARRL’s Logbook of The World (LoTW). Registration is free, and it costs nothing to use LoTW. Many hams are familiar with grid squares from the VHF/UHF and satellite realms, and everyone lives in one. ARRL’s VUCC is based on grid squares, and some contests on HF, as well as on VHF and UHF, also use them as a scoring factor.
John Morris, G4ANB, came up with the locator system, which the VHF Working Group adopted in 1980 at a meeting in Maidenhead, England — thus the term “Maidenhead grid square.” The system divvies up the entire globe into 324 fields, each containing 100 grid squares 1° latitude by 2° longitude in size. With 32,400 potential grid squares, it’s not likely that anyone will run out of challenges, even though some grid squares are surrounded entirely by water, are in areas that are uninhabited, or are difficult to access.
If you don’t know your grid square, David Levine, K2DSL, has an online calculator. Just enter a postal address, ZIP code or a call sign, and his site will tell you the grid square for that location. For example, enter “W1AW” and the site will return “FN31pr.” For the purposes of the ARRL International Grid Chase, though, just the two initial letters and the two numbers that follow (e.g., FN31) are all you need to know.
Once you get active in the chase and start uploading your log data, each new grid square contact confirmed through LoTW will count toward your monthly total. Getting started is simple: Turn on the radio and call CQ or “CQ Grid Chase,” or listen for others doing the same. Make the contact, exchange grid squares, log it, and move on to another. At the end of each month, your totals on the Grid Chase Leader Board will reset to zero, although the system retains all monthly data to determine top finishers in various categories at the end of the year.
Any contact you make in 2018 can count for your Chase score; it doesn’t have to involve an exchange of grid squares. As long as the other operators participate in LoTW, you’ll get credit automatically when they upload their logs. This means that contest contacts will also count, as will contacts with special event stations, or other on-air activity that uses LoTW to confirm contacts.
Some radio amateurs live in sparsely populated grid squares, and if you’re one of those, you could find yourself handling a pileup! Expeditions to hard-to-reach or rare grid squares will undoubtedly evolve. You also can travel to one of those grid squares yourself. Some vehicle or hand-held GPS units can be set to display when you are in a particular grid square. Apps are available for smartphones or tablets, such as Ham Square for iOS devices or HamGPS for Android devices.
There are no restrictions on modes or bands, as long as they are legal. Satellite contacts are valid for the Chase. The event is open to all radio amateurs.
As all contacts are uploaded to LoTW, participants may use their contacts toward other ARRL awards, in addition to the overall monthly and annual Grid Chase recognitions. These other ARRL awards include the grid-based VHF-UHF Century Club (VUCC) and Fred Fish Memorial Award, as well as Worked All States (WAS), WAS Triple Play, DX Century Club (DXCC), and Worked All Continents (WAC).
Complete details of the ARRL International Grid Chase will appear in the December 2017 issue of QST. The digital edition is available on Friday, November 10.

The ARRL International Grid Chase
Get ready to kick off 2018 with a new year-long operating event!

You may not know this, but your station is in a Maidenhead grid square. The entire world is divided into thousands of these 1° latitude × 2° longitude squares, each one with a unique designation. They’re all part of a geographic location system adopted in the 1980s at a meeting of the VHF Working Group in Maidenhead, England.
Unless you are a VHF enthusiast, this nugget of information may not mean much. But at 0000 UTC on January 1, 2018, the global Amateur Radio community will be very interested in grid squares.
Get in the Chase
The objective of the ARRL International Grid Chase is simple: Work stations in as many grid squares as possible and upload your log data to ARRL’s Logbook of The World. If you are not currently registered with Logbook of The World, this is a good reason to get started. Go to https://lotw.arrl.org/lotw-help/getting-started/. Registration and uploading are free.
Every new grid square contact confirmed through Logbook of The World counts toward your monthly total, so you have an incentive to start the chase as soon as you ring in the New Year.
Just turn on your radio and start calling “CQ Grid Chase,” or listen for others doing the same. Make the contact, enter it into your log, and you’re on to the next (see the sidebar, “Tips for the Chase“).
At the end of each month, your totals on the Grid Chase leader board will reset to zero. Fear not, though. The online scoring system will maintain your monthly totals for a grand total at the end of the year, when an annual summary will be released and awards given to top finishers in various categories.
The ARRL International Grid Chase is open to all amateurs, regardless of location or license class. Any operating mode is eligible as well as every band, except 60 meters. You’ll find the complete rules at www.arrl.org/aigc2018.
But What’s My Grid Square?
Determining your grid square is easy. David Levine, K2DSL, has a great online calculator at www.levinecentral.com/ham/grid_square.php. Just enter a postal address, zip code, or even a call sign, and David’s site will tell you the grid square for that location.
For example, enter “W1AW” and the site will return “FN31pr.” The letters “pr” designate the grid square field, but you won’t need that for the Chase. Just FN31 will do.
The ARRL online store (www.arrl.org/shop) also offers grid square maps of the US and Canada, as well as a grid square atlas of the entire world.
Plenty of Pileups
Figure 1 — Grid square FN51 is mostly salt water, except for a narrow strip of land along the “sole” of Cape Cod and a portion of southeastern Nantucket Island. This image is taken from the ARRL Amateur Radio Map of North America, available at www.arrl.org/shop.
Some grid squares have thousands of amateurs in residence, but others have only a few, or none. Those “rare” grid squares will be hot properties in 2018, and hams operating from those locations can expect serious pileups.
Of course, nothing prevents you from hopping into your car and driving to a grid square where you are the only amateur on the air. There are some grid squares in coastal areas, for example, where most of the territory is comprised of water. Look at Figure 1 and notice that grid square FN51 is mostly in the Atlantic Ocean, except for a relatively narrow strip along the “sole” of Cape Cod and a small portion of southeastern Nantucket Island.
If you’re taking to the road, some vehicular GPS systems will display grid square locations. You can also use apps for your smartphone or tablet, such as Ham Square (iPhone, iPad) or HamGPS (Android).
However you play it, the ARRL International Grid Chase is going to be big. By the time you read this, “opening day” will be less than 2 months away. Better sign up with Logbook of The World (if you haven’t already) and prepare your gear!

Tips for the Chase
- Any contact can count for your Chase score; it doesn’t have to involve an exchange of grid squares. As long as other operators participate with Logbook of The World, you’ll get the credit automatically when they upload their logs. This means that contest contacts will count, as will contacts with special-event stations, or any other on-air activity. As long as stations upload their logs to Logbook of The World, you’re good.
- The new FT8 digital operating mode is ideal for the ARRL International Grid Chase. You can set up FT8 to call CQ and automatically respond, completing a contact in a little over a minute while you watch. When the contact is complete, simply click your mouse to trigger another CQ. You’ll find FT8 within the free WSJT-X software suite at https://physics.princeton.edu/pulsar/k1jt/wsjtx.html.
- Watch for Logbook of The World users on your favorite online DX clusters. Most clusters have the ability to filter and display only stations that participate in Logbook of The World; other clusters can at least flag the stations with a symbol. This will save time when you are looking for contacts to increase your score. If you enjoy JT65, JT9, or the FT8 digital modes, check out the free JTAlert for Windows at http://hamapps.com. This software works with JT65-HF or WSJT-X applications to automatically flag Logbook users and will even alert you when a station is on the air in a needed grid square.
- Upload often. Grid Chase totals are refreshed at the end of each month. With that in mind, it pays to send new data to Logbook of The World every couple of days, or even daily.
- Satellite contacts count. Contacts made through earthbound repeaters do notcount for the Grid Chase, but repeaters in outer space are the exception. There are low-orbiting satellites that support CW, SSB, and even FM contacts. See the AMSAT-NA website at www.amsat.org.
- Try “circling” grid squares. It’s easy to set up a portable or mobile operation at the intersections where corners of grid squares meet. For example, you could operate in one grid square and then drive west across the “border” into the next square. Make some contacts there and then drive north into the adjacent square. Bang out more contacts, and then head east into another grid square. This is a very common technique used by VHF “rover” operators. In a single day, you can operate from four different grid squares!
- Take the Chase on vacation. Take a radio along when you travel and work new grid squares at your destinations. Even a handheld FM transceiver can be used to work a new square on a simplex frequency.

2018 International Grid Chase Rules
2018 ARRL International Grid Chase Rules
In the spirit of the Fred Fish Memorial Award, VUCC, DXCC, WAS and WAC, we bring you a world-wide event in which all Radio Amateurs can participate where the goal is to contact (each Month during 2018) as many maidenhead 4-digit grid squares as possible on all amateur bands.
Building on our successful 2016 National Parks On The Air (NPOTA) event (providing a year-long focus of fun activating or contacting US National Parks), and considering ARRL’s existing grid-square based award events (including our Fred Fish and VUCC Award programs where the objective is to contact stations in as many 4-digit maidenhead grid squares as possible), we introduce for 2018 the ARRL International Grid Chase to bring international grid-chasing on all amateur bands (HF, and VHF and above) to an all new level.
In a fashion similar to NPOTA, using Logbook of the World (LoTW – see http://www.arrl.org/logbook-of-the-world) as the QSOs data source, the 2018 ARRL International Grid Chase activities will be scored MONTHLY on the ARRL web site at http://www.arrl.org/aigc2018. Each month we will start fresh, recognizing participation through various tables and data selection options on the web page. Monthly pages will be added to track each calendar month’s activities. Once the year is completed, an annual summary will be released.
- 1. Objective: On a Monthly basis, on amateur frequencies from HF to Microwaves, to contact amateur stations in as many different 2 degrees by 1 degree maidenhead 4-digit grid squares as possible.
- 2. Dates/Event Period: The event runs from 0000 UTC January 1, 2018 through 2359 UTC December 31, 2018. At the beginning of each month during 2018, the monthly scores will be reset to zero to begin the new month of competition.
- 3. Bands: All FCC-authorized frequencies (excluding the 60 meter and 600 meter bands). Permitted bands: 160m, 80m, 40m, 30m, 20m, 17m, 15m, 12m, 10m, 6m, 2m, 1,25m, 70cm, 33cm, 23cm, and all higher FCC-authorized microwave bands.
- 4. Modes: Three mode categories will be recognized – CW, Phone and Digital (all voice modes count as Phone, all digital modes count as Digital).
- 5. Methods of contact: All methods of contact are permitted (excluding QSOs made through repeaters, digipeaters, Echolink, IRLP, or non-satellite cross-band QSOs which do not count in this event). Satellite and EME QSOs are permitted.
- 6. Station types: Fixed, Portable, Mobile/Rover and Maritime Mobile (MM) stations may participate (MM stations are not eligible for DXCC, WAS or WAC credit however).
- 7. Exchange: Call Sign and Maidenhead 4-digit grid-square locator (see www.arrl.org/grid-squares). Exchange of signal report is optional. When operating during a contest, the contest exchange takes precedence over the grid square exchange. QSOs made with a club or special event (eg, 1×1) call count only for the club, not for the operator. As with other similar award’s criteria, if a station is located on the intersection of 2, 3 or 4 grid squares, the over-the-air exchange need only include just one grid square (confirmation for the adjoining grid squares will be made by the station operating from the intersecting grids through the station location in TQSL https://lotw.arrl.org/lotw-help_devel_en/stnloc/?lang=en).TQSL Station Locations will allow multiple adjacent grids (formatted as “grid,grid,” etc). MM stations would have DXCC Entity set to “none”. For information on LoTW TQSL, see http://www.arrl.org/quick-start-tqsl.
All QSOs within your DXCC entity qualify.
See also section 9 below for Awards with specific requirements.
- 8. Event participation – contact submissions: All submissions are made through LoTW. See https://lotw.arrl.org/lotw/default
- 9. Awards: As all contacts are being uploaded to LoTW, in addition to the overall monthly and annual recognitions of the ARRL International Grid Chase, participants may use their contacts toward other ARRL awards (see the list of ARRL awards at http://www.arrl.org/awards). These include ARRL’s grid-based awards of VHF-UHF Century Club (VUCC) and the Fred Fish Memorial Award (for contact with all 488 US 4-digit grid squares on 6 meters), as well as Worked All States (WAS) and WAS Triple Play, DX Century Club (DXCC), and Worked All Continents (WAC).
- 10. Recognitions: Achievement in collecting grid squares in the ARRL International Grid Chase will be recognized by categories of Band, Mode, and Continent (other leaders types will be developed as warranted) through our interactive web page monthly and at year end summary. Online certificates of achievement will be developed for Monthly and Annual recognition.
- 11. Resources: A variety of resources offer grid-square maps and mapping tools.
