The HRFIO (sometimes abbreviated as RFIO) board is the RF input/output switching matrix board for the FLEX-5000. This is a small board mounted to the back on the FLEX-5000 that contains all of the antenna connectors for the radio. This includes the three (3) SO-239 (UHF) transceiver ports, the RX1-IN/RX1-OUT loop BNC connectors, the RX2-IN, the 144 MHz, XVTX/COM and XVRX transverter BNC connections.
