  • description: Today I'm showing you a project that I think is one of the most interesting I've done on the channel: a radio switcher for a single antenna, designed with very strict specifications. This design, with its built-in protections, will undoubtedly prevent any misuse, allowing three transceivers to transmit to the same antenna (only one at a time, of course) without interference between them. I'm trying to dispel the myths that this isn't possible or that it's not a good idea.
