The Parks on the Air (POTA) program has gained tremendous popularity in the amateur radio community, combining the passion for making radio contacts with outdoor activity. The POTA Activity section in the Hamtrax digital toolkit was designed from the ground up to make operating as easy and efficient as possible, both for activators transmitting from parks and for hunters looking to make contacts with them.
For operators working in the field, the application offers a quick way to start an activation — simply select a park from the directory or use GPS location. Hamtrax automatically creates a dedicated logbook folder, submits a self-spot to the POTA network, keeps a live count of contacts, and identifies Park-to-Park (P2P) contacts. Hunters, meanwhile, have access to an interactive world map and a real-time list of spots. With filtering by band and mode (SSB, CW, FT8), finding the park or operator you are looking for takes only a few seconds.
A key advantage of the application is its Local-First architecture, designed specifically for field operations. All contacts are immediately saved on the device, so losing cellular coverage in a forest or on a mountain peak does not put your data at risk. Once connectivity is restored, the application automatically synchronizes entries with the cloud, allowing users to instantly export logs in the standard ADIF format or directly to the official POTA service.
In addition to POTA functionality, the platform offers a collection of useful field tools, including a real-time Morse code (CW) decoder using the phone's microphone, live ionospheric condition monitoring, an interactive band plan, and tools for monitoring your own signal reach through the Reverse Beacon Network and PSK Reporter.
The application is cross-platform and free in its basic version. It can be used directly in a web browser at hamtrax.com, while native versions are available from the Google Play Store (Android) and Apple App Store (iOS). For users looking for documentation and detailed guides, an official documentation portal is also available at docs.hamtrax.com.
