I just wanted to let any of the owners of various Yaesu radios that have ports to add the uTune accessory, that these ports can be used to obtain shared access to the antenna for an SDR. The utune ports are an in and out port. They are RCA style female plugs. All you need to do is get a 3 way rca splitter, so that it bridges the in and out, and then use the 3rd end of the splitter to connect your SDR unit. Press the utune button on the radio and you will now have the receive signal passing from in to out port, and that signal is shared with your SDR. No IF tap, no antenna switcher required. Excellent isolation of the SDR during transmit. I am now using this on my FT-950, but many radios ( FT-950, FT-2000, FT-DX1200, FT-DX3000, FT-DX5000, & FT-DX9000 series radios) have the utune ports.
