RF remotes generally work this way: The originating signal is sent from the remote as RF (radio frequency.) In the case of the MX-950 in my theater that's 418MHz, a very stable and reliable frequency band.
By nature, propane is clear and contains no scent at all. For safety purposes propane. companies add a substance known as ethyl-mercaptan to the propane fuel. Ethyl-. mercaptan has a strong rotten egg, or skunk-like scent, which allows the consumer to. smell it in the case of a leak.
Natural gas doesnât actually smell like anything. Thatâs why we add a chemical called methyl mercaptan (methanethiol) to natural gas so youâll be able to smell it in case of a leak. Mercaptan has a very distinct and unpleasant odor that many people compare to the smell of rotten eggs.
