This assures FB RX isolation using FT1000MP's T/R antenna switching + additional in-series Swbox switching/protection. The simple basic control head has a diode matrix to output BCD from 000 though 111 to select up to eight antenna ports. It's not possible to connect the RX only SDR together with the TX radio via a standard splitter because the TX radio's power will most likely blow up the SDR with it's powerful output. Equipped with Bias-T, Enable or Disable with Functionally, when the controller is OFF, the main TX/RX antenna goes to the SDR RX output and includes 10mW RF limiter protection. This feature can be bypassed by the switch, so that the TX antenna can be used for both RX I designed the RCS-10 many years ago while engineering for Ameritron.
