The most direct and easy way to create a complete radio system is to use one of our complete RF frontend daughterboards, the TVRX2, DBSRX2, WBX, SBX, RFX-series, and XCVR2450. However, you can use the BasicRX and BasicTX with your own external RF hardware. For reception you would need to add gain and filtering in front of the BasicRX daughterboard. This can be done pretty easily with Mini-Circuits® parts, or you can use the 10.7 MHz IF output of common scanners and receivers. The BasicRX board will handle signals up to around 300MHz directly. For higher frequencies you'll need to downconvert.
