The program was developed for radioamateurs who participate in the RDA and RAFA diploma program. The program sends your current coordinates to the TNXQSO.com server and receives your current RDA, locator and RAFA in response. Information update - every 10 or 60 seconds. But for radio amateurs outside the borders of Russia, this program will be useful as an information service for the operation of your station/expedition. ------------------------------- Программа отправляет текущие координаты на сервер TNXQSO.com и получает в ответ ваш текущий RDA, локатор и RAFA. Если вы находитесь на расстоянии 100-150 метров до границы двух районов, то программа покажет оба.
