Special thanks to Ray Montagne (W7CIA) who helped get the new .gpx filetype exports configured. In case you are wondering what they are and how you can use them, keep reading.

Here is the e-mail that started it all off

"Could you please, please, please use a platform agnostic encoding for exporting files (such as .zip) rather than using a Windows platform dependent self extracting format? The Windows format, which has a '.exe' file extension, cannot be extracted on a Macintosh. A standard '.csv' file or a '.csv' file that is in a '.zip' archive can be used on a Macintosh (or Linux). Same goes for Garmin files, which are based on XML and have a '.gpx' file extension. Thank you. Ray Montagne, W7CIA"

I still haven't figured out why he is seeing a .exe when trying to download a .csv from a Mac platform, but the last line really caught my attention. I have never exported to a Garmin application. PHP can easily be written to export as XML. After asking more about it, Ray was more that helpful in pointing me in the right direction:

"For reference, I converted the Idaho Repeater data into a '.gpx' file that can be imported into Garmin Basecamp (a free application available at <http://www.garmin.com/us/products/onthetrail/basecamp>).Free map data, including topographical maps, is available at <http://www.gpsfiledepot.com/maps/>.Once imported into Garmin Basecamp, the file can be uploaded into any Garmin GPS.The '.gpx' file format is derived from XML and is specified at <http://www.topografix.com/gpx.asp>.

Having the repeater directory in my GPS is why I needed access to the '.csv' data on a Macintosh (I had to use a Windows system and then transfer the data).


The web site Ray provided are very easy to understand, and I had to have a copy of BaseCamp. From the web site:

Trip Planning

Use BaseCamp to plan your next hiking, biking, motorcycling, driving or off-roading trip. You can view maps, plan routes, and mark waypoints and tracks from your computer and then transfer them to your device.

  • Track Draw feature lets you trace your planned route and view elevation changes, helping you estimate the difficulty of a hike or bike ride.
  • Plan the perfect scenic route, making sure your navigator takes you through certain waypoints, for your next road trip.
  • Play back your routes and tracks over time and save and share your adventure.

Survey the Terrain

BaseCamp displays your topographic map data in 2-D or 3-D on your computer screen, including contour lines and elevation profiles. Load map data from your handheld device, or import maps you’ve downloaded or purchased on DVD or microSD™ card. Consider our TOPO series maps, which offer detail on a scale of either 1:100,000 or 1:24,000.


Geotag Photos

BaseCamp lets you geotag photos, associating them with specific waypoints. You can see the exact scenery at any given location. Transfer the photos to your handheld device, publish photos directly to Picasa™, or email your geotagged photos directly to friends or family so they can navigate right to your favorite spots in the future.

Transfer Satellite Images

With BaseCamp and a BirdsEye Satellite Imagery subscription, you can transfer an unlimited amount of satellite images to your outdoor or fitness device and seamlessly integrate those images into your maps to get a true representation of your surroundings. It makes it easy to scout campsites, sources of water, potential hazards and more. If you prefer raster topographic maps, you can also download BirdsEye Select maps and pay only for the data you download.

Downloading and installing BaseCamp was absolutely painless. Installing extra map files was also a snap (be sure to read the directions, though).

The best information on how to create the .gpx export actually came from Ray. He spent some time creating some example files, which I copied and uploaded. They have been deployed and are working nicely.

They are in sort of a beta mode and have not been deployed on the entire site. The best way to download one is to search on a specific state and then choose the band (or ALL) you want to view. On the Search Result page, choose Export, then .gpx. After the file downloads, open it from File >> Import inside BaseCamp.

I love the Proximity Search. Essentially, enter in coordinates, an address, a landmark, or whatever Google knows how to decode, and let the search engine run through the database looking for repeaters that are close to that location.

To filter the results down, you select the distance from the search location. If you only want to look on a particular band, you can do that, too. You should never enter a band and a frequency; it's one or the other.

There is a healthy list of features you can filter by as well as by confirmation that the repeater is operational.

I use this search all the time to locate repeaters near me. When using my HT at a hotel in another city, I will look for repeaters that are within 20 miles of me with wide area coverage. It's a fast way to locate repeaters when you don't know what the nearby cities or mountain tops are called...or maybe even the county you are in. You can search for repeaters around you like you have local knowledge!

This search has been used by disaster relief organizations to locate repeaters to serve remote operational areas during disaster relief situations. You could even use it to locate a repeater at a remote camp site or trail somewhere. This search really takes the research out of your search of a paper directory to help you find usable repeaters.

The search results will tell you how far away the repeater is to the location you entered.

An added bonus for smart phone users, there is a "Near Me' search which will use your onboard GPS to autofill your location! I use this a lot at the hotels and even on the road between major cities to find repeaters.

This search ignores all political lines, including international. It will search for close repeaters regardless of city, county, state, provincial, or international boundaries.

Happy searching!

The Nationwide Repeater Seach actually provides two different search types:

  1. Search by Band
  2. Search by Feature

You cannot choose individual states and provinces, you are searching either the entire U.S. and/or Canada. These are scaled down saeches for bands and features that are more niche within the HAM community.

Search by Band

You can search for all repeaters on the following bands only:

  • 10 meter
  • 6 meter
  • 33 cm
  • 23 cm

Search by Feature

You can search for almost all digital voice modes, VOIP, and ATV here. This is the best search for locating these repeaters.

  • ATV
  • D-Star
  • EchoLink
  • IRLP
  • AllStar
  • P25

You can even filter by the specified band and restrict to on-air only.

The Advanced Search is where the power is. Since the web site is database driven, we can basically create a search on any one of the fields in the database. This particular form should be seen as a series of filters. Look at it as starting with the entire database, some 20,000 repeaters, and entering criteria to slice away repeaters until you get the result you are looking for. A note to remember, all the fields are optional. You can enter as much or as little data as you choose to get the result.

The first slice is the choosing of the state(s) and/or province(s) you wish to search. You can choose just one or many by holding down the Control button on your keyboard as you click additional state(s) and/or province(s). This is an inclusion filter which means only the

The next fliter is by band or frequency. You would never select both! This field is completely optional, but entering something will filter down the results. An example is when you live in a Tri-state area and you hear a repeater on a particular frequency. You may want to do a reverse search based on the frequency to find out which repeater it was. Just select the states you want to query along with the frequency with the repeater and your answer will be within the results!

You could stop here, for example if you just wanted to retrieve all of the 900 MHz repeaters out of Arizona, but there is still a lot more filtering you can do!

If you want to search for all the repeaters that have a particular call sign, you can enter it here. If you leave all the fields blank, you will get all of the repeaters in the database with that call sign no matter what band or state/province they are in. Use the filters to narrow the search, if needed.

The features filter is extremely limited, by design. If you want to search for just repeaters with autopatch or emergency power, select one. If you want to search nationwide for repeaters with digital modes, use the Nationwide Search.

If you want to search only for repeaters that are known to have wode area coverage, select the appropriate bullet under the Coverage category.

If you want to search only for repeaters that someone has confirmed as "on-air", select the appropriate bullet under the Operational Status category.

Finally, you can sort the results by frequency, state, or update date.

Happy Searching!
