This cable is for Yaesu FT-1000 and other Yaesu radios that have a rear panel 4 pin DIN RTTY connector for FSK input and Fixed Level Audio output. The mini-plug labeled "FSK" connects to the "Key Out" connector of the RIGblaster Plus II and Plus, "FSK Out"(R6) on a RIGblaster Pro or "CW/FSK" on a RIGblaster Advantage for direct FSK keying of your Yaesu radio from programs that support direct FSK keying such as Hamscope, MMTTY, MixW, etc.. The un-labeled mini-plug provides fixed level audio from the 4 pin RTTY din connector to the Sound Card Line In or "Audio In"(R11) on a RIGblaster Pro or "AUDIO OUT" on a RIGblaster Advantage for reception of all digital modes. PTT is NOT connected through this cable. Computer control of PTT is enabled through the Mic connection.
Note: If you do not have a RIGblaster Plus II, Plus, Pro or RIGblaster Advantage and if your Yaesu radio does not have a 4 pin din rear panel RTTY Jack, do not order this cable.
