This allows other software to be built on top of it.</p>
     <p>The API is deliberately well-defined with an <a href="/apidocs/openapi.yml">OpenAPI specification</a> and <a href="/apidocs">API documentation</a>. The API delivers spots in a consistent format regardless of the data source, freeing developers from needing to know how each individual data source presents its data.</p>
     <p>Spothole itself is also open source, Public Domain licenced code that anyone can take and modify. <a href="https://git.ianrenton.com/ian/metaspot/">The source code is here</a>. If you want to run your own copy of Spothole, or start modifying it for your own purposes, the <a href="https://git.ianrenton.com/ian/spothole/src/branch/main/README.md">README file</a> contains a description of how the software works and how it's laid out, as well as instructions for configuring systemd, nginx and anything else you might need to run your own server.</p>

     <p>Spothole is an "aggregator" for those spots, so it checks lots of different services for data, and brings it all together in one place. So no matter what kinds of interesting spots you are looking for, you can find them here.</p>
     <p>As well as spots, it also provides a similar feed of "alerts". This is where amateur radio users who are going to interesting places soon will announce their intentions.</p>
     <h4 class="mt-4">What are "DX", "DE" and modes?</h4>
-    <p>In amateur radio terminology, the "DX" contact is the "interesting" one that is using the frequency shown. They might be on a remote island or just in a local park, but either way it's interesting enough that someone has "spotted" them. The callsign listed under "DE" is the person who spotted the "DX" operator. "Modes" are the type of communication they are using. You might see "CW" which is Morse Code, or voice "modes" like SSB or FM, or more exotic "data" modes which are used for computer-to-computer communication.</p>

The callsign listed under "DE" is the person who entered the spot of the "DX" operator. "Modes" are the type of communication they are using.

+    <p>Spothole can retrieve spots from: Telnet-based DX clusters, the Reverse Beacon Network (RBN), the APRS Internet Service (APRS-IS), POTA, SOTA, WWFF, GMA, WWBOTA, HEMA, Parks 'n' Peaks, ZLOTA, WOTA, the UK Packet Repeater Network, and any site based on the xOTA software by nischu.</p>
+    <p>Spothole can retrieve alerts from: NG3K, POTA, SOTA, WWFF, Parks 'n' Peaks, WOTA and BOTA.</p>
+    <p>Note that the server owner has not necessarily enabled all these data sources. In particular it is common to disable RBN, to avoid the server being swamped with FT8 traffic, and to disable APRS-IS and UK Packet Net so that the server only displays stations where there is likely to be an operator physically present for a QSO.</p>
+    <p>Between the various data sources, the following Special Interest Groups (SIGs) are supported: Parks on the Air (POTA), Summits on the Air (SOTA), Worldwide Flora & Fauna (WWFF), Global Mountain Activity (GMA), Worldwide Bunkers on the Air (WWBOTA), HuMPs Excluding Marilyns Award (HEMA), Islands on the Air (IOTA), Mills on the Air (MOTA), the Amateur Radio Lighthouse Socirty (ARLHS), International Lighthouse Lightship Weekend (ILLW), Silos on the Air (SIOTA), World Castles Award (WCA), New Zealand on the Air (ZLOTA), Keith Roget Memorial National Parks Award (KRMNPA), Wainwrights on the Air (WOTA), Beaches on the Air (BOTA), Worked All Britain (WAB), Worked All Ireland (WAI), and Toilets on the Air (TOTA).</p>

Spothole does the hard work of taking all the various data sources and providing a consistent, well-documented data set. You can then do the fun bit of writing your own application.</li>

     <h4 class="mt-4">Why does this website ask me if I want to install it?</h4>
     <p>Spothole is a Progressive Web App, which means you can install it on an Android or iOS device by opening the site in Chrome or Safari respectively, and clicking "Install" on the pop-up panel. It'll only prompt you once, so if you dismiss the prompt and change your mind, you'll find an Install / Add to Home Screen option on your browser's menu.</p>

     <p>To avoid putting too much load on the various servers that Spothole connects to, the Spothole server only polls them once every two minutes for spots, and once every hour for alerts. (Some sources, such as DX clusters, RBN, APRS-IS and WWBOTA use a non-polling mechanism, and their updates will therefore arrive more quickly.) Then if you are using the web interface, that has its own rate at which it reloads the data from Spothole, which is once a minute for spots or 30 minutes for alerts. So you could be waiting around three minutes to see a newly added spot, or 90 minutes to see a newly added alert.</p>
     <h4 class="mt-4">What licence does Spothole use?</h4>
     <p>Spothole's source code is licenced under the Public Domain. You can write a Spothole client, run your own server, modify it however you like, you can claim you wrote it and charge people £1000 for a copy, I don't really mind. (Please don't do the last one. But if you're using my code for something cool, it would be nice to hear from you!)</p>
+    <h2 class="mt-4">Data Accuracy</h2>
+    <p>Please note that the data coming out of Spothole is only as good as the data going in. People mis-hear and make typos when spotting callsigns all the time. There are also plenty of cases where Spothole's data, particularly location data, may be inaccurate. For example, there are POTA parks that span multiple US states, countries that span multiple CQ zones, portable operators with no requirement to sign /P, etc. If you are doing something where accuracy is important, such as contesting, you should not rely on Spothole's data to fill in any gaps in your log.</p>
     <h2 id="privacy" class="mt-4">Privacy</h2>
     <p>Spothole collects no data about you, and there is no way to enter personally identifying information into the site apart from by spotting and alerting through Spothole or the various services it connects to. All spots and alerts are "timed out" and deleted from the system after a set interval, which by default is one hour for spots and one week for alerts.</p>
     <p>Settings you select from Spothole's menus are sent to the server, in order to provide the data with the requested filters. They are also stored in your browser's local storage, so that your preferences are remembered between sessions.</p>
     <p>There are no trackers, no ads, and no cookies.</p>
     <p>Spothole is open source, so you can audit <a href="https://git.ianrenton.com/ian/spothole">the code</a> if you like.</p>
+    <h2 class="mt-4">Thanks</h2>
+    <p>This project would not have been possible without those volunteers who have taken it upon themselves to run DX clusters, xOTA programmes, DXpedition lists, callsign lookup databases, and other online tools on which Spothole's data is based.</p>
+    <p>Spothole is also dependent on a number of Python libraries, in particular pyhamtools, and many JavaScript libraries, as well as the Font Awesome icon set and flag icons from the Noto Color Emoji set.</p>
+    <p>This software is dedicated to the memory of Tom G1PJB, SK, a friend and colleague who sadly passed away around the time I started writing it in Autumn 2025. I was looking forward to showing it to you when it was done.</p>

     Spothole is a utility to aggregate "spots" from amateur radio DX clusters and xOTA spotting sites, and provide an open JSON API as well as a website to browse the data.
     
     While there are other web-based interfaces to DX clusters, and sites that aggregate spots from various outdoor activity programmes for amateur radio, Spothole differentiates itself by supporting a large number of data sources, and by being "API first" rather than just providing a web front-end. This allows other software to be built on top of it. Spothole itself is also open source, Public Domain licenced code that anyone can take and modify.
+    
+    The API calls described below allow third-party software to access data from Spothole, and receive data on spots and alerts in a consistent format regardless of the data sources used by Spothole itself. Utility calls are also provided for general data lookups.
+    
+    Please note that the data coming out of Spothole is only as good as the data going in. People mis-hear and make typos when spotting callsigns all the time, and there are plenty of areas where Spothole's location data may be inaccurate. If you are doing something where accuracy is important, such as contesting, you should not rely on Spothole's data to fill in any gaps in your log.
