HamAlert - an application that guards the bands for you
HamAlert is a practical application and online service for radio amateurs that allows setting notifications for the appearance of specific stations, countries, modes, or bands. It works based on data from sources such as DX cluster, RBN, PSK Reporter či WSPR.
The user can set filters according to the call sign, DXCC, IOTA, band, mode, geographical area or even type of spot. After the conditions are met, the application sends a notification in the form of a push notification, email, or Telegram message.
