VOACAP goes Online

    By Jari Perkiömäki OH6BG


    I am glad to inform that making point-to-point HF propagation predictions is now easier than ever as VOACAP Online has been opened to the public. The service uses VOACAP (Voice of America Coverage Analysis Program) which is arguably one of the best HF prediction engines available on the market today.

    VOACAP Online is free to all and makes using VOACAP a no-brainer. Just enter the coordinates of the transmitter and the receiver, and that’s all. To find the coordinates, you can use the Google Maps based QTH Locator at http://www.voacap.com/qth.html

    The prediction is given as a “circuit reliability” graph that shows the probability of achieving a CW-grade transmission quality between the transmitter and the receiver.

    VOACAP Online is brought to you by Jari Perkiömäki OH6BG, James Watson HZ1JW and Juho Juopperi OH8GLV.
