And I want share AF/FM ANT,Now Im at draw schematic,I haven't studied RF circuits,Just want try

Those parts are really there to switch between am sw or fm and it would either put different parts in the circuit or take them out depending on what transistor is active or not you really don't need all that stuff just if you wanna use all the features of this ic I honestly just got the boards and assemble them so I haven't really had alot of time to test it I know I should put that in the read me but I will have code wrote here soon to drive this chip with the nucleo

Thank your reply,I will use ESP32-S3 dirve,use double SI7443/SI745,first chip play voice,second chip scan RF single,Maybe that fun!just like SDR(LOW level)
