Na co chces pipak? Si snad myslis, ze by te nekdo hledal?
ELECTROMAGNETISM AND THE FUTURE OF AVALANCHE TRANSCEIVERS. John Hereford píše:An advantage of using the (656 m) long wavelength(λ) 457 kHz signal for companion rescue is that there is little attenuation or effect by objects such as snow, the body, metal, trees, and rocks. There is no “multi-path,” which means that the signal does not bounce or reflect off of objects in the backcountry, which would present confusion in location systems
Pieps website píše:457 kHz is the wave length that permeates best through snow. The less air that exists in the snow, the harder it is for the signal to propagate and the receiving range is reduced. An extreme range reduction occurs at low snow thickness (<1m) or in glacial ice, since it has only a very small portion of air. The recommended search strip widths are no longer valid! If an avalanche transceiver is sending signals with values at the limit of standard or outside the standard, some receiving avalanche transceivers can be challenged with performance degradation.
Tak, tak. Kdo to nezkusil, ma jen predstavy, jake to muze byt a predstavy lidi jsou nekdy hodne daleko od skutecnosti (napr. si plivnu, abych vedel kde je dole a hore ) - kdo to zkusil, tak to vi a vetsinou si fakt da priste mnohokrat vetsi pozor. A kdyz se nekomu "postastni" stat se vyhledavanou obeti, vydrzi to a zustane pod snehem delsi dobu, kym jej nenajdou a nevyhrabou ostatni ucastnici kurzu, tak ten si na to rozhodne spomene pri kazdem vstupu na snih v horach (a mozna si v brzke dobe koupi i lavinovy batoh).FrantaKrajta píše:A kdyz se na kurzu jako bonus nechas cely zahrabat snehem, aspon budes o to pecliveji v budoucnu planovat tury

Uplne jsem nepochopil, co se jim stalo. Ze by se "samo" prenul pipak na tele z vysilani na hledani nebo vypnuti posunutim tlacitka? To se mi na nich nezda.wertigo píše:Možný problém s pieps dps
