Intermodulační rušení
(14.11.2002)
Představte si situaci, kdy tři kamarádi si
šli zalétat. Kontrola na zemi, vše v pořádku. Pořádně vytáhnout antény a
hurá do vzduchu a najednou jeden letoun to bere přímo k zemi! Evidentně
rušení, ale jak to ? Vždyť máme každý jiný kanál ?!
Při provozu dvou a nebo více RC vysílačů současně může docházet k tzv. intermodulačnímu rušení. RC vysílače nejen že vysílají, ale na jejich
anténě dochází i k příjmu signálu z jiného RC vysílače. Při správné
konstelaci kanálů může dojít rušení. Které kanály při současném provozu se
"ohrožují", ukazují tyto tabulky:
Podrobnější vysvětlení celé problematiky
