Ham operators seek to exploit the limits of the frequencies usual characteristics looking to learn, understand, and experiment with the possibilities of these enhanced propagation modes. Sporadic band openings[ edit ] Occasionally, several different ionospheric conditions allow signals to travel beyond the ordinary line-of-sight limits. Some amateurs on VHF seek to take advantage of "band openings" where natural occurrences in the atmosphere and ionosphere extend radio transmission distances well over their normal range. Many hams listen for hours hoping to take advantage of these occasional extended propagation "openings".

Advances in technology have always gone hand-in-hand with our radio hobby-—indeed, in many cases, those advances originated with our hobby. There are a multitude out there, and most are either free or very inexpensive. Exam preparation HamStudy.
