Labradoodle Labradoodle A Labradoodle () is a crossbreed dog created by crossing the Labrador retriever and the standard, Moyen, or Miniature poodle. The term first appeared in 1955, but was not popularized until 1988, when the mix began to be used as an allergy friendly guide dog. Not all Labradoodles are hypoallergenic, but it is a quality that many look for and appreciated in this type of crossbreed. The labradoodle became known in 1988, when Australian breeder Wally Conron crossed the Labrador Retriever and Standard Poodle at the Royal Guide Dogs Associations of Australia in Victoria. Conron's intent was to combine
Low frequency can be received up to from the transmitting antenna. Low frequency waves can also occasionally travel long distances by reflecting from the ionosphere (the actual mechanism is one of refraction), although this method, called "skywave" or "skip" propagation, is not as common as at higher frequencies. Reflection occurs at the ionospheric E layer or F layers. Skywave signals can be detected at distances exceeding from the transmitting antenna. In Europe and Japan, many low-cost consumer devices have since the late 1980s contained radio clocks with an LF receiver for these signals. Since these frequencies propagate by ground wave only, the
