xylofoejs yes, but sound. quality is low or the same as phone.

xylofoejs the wireless detectors trasmit on 433 MHz. but the question was about the RFID tags... they are 125kHz. 13 MHz doesn't work with the hosa system.

xylofoejs yes it do support RDS. however, if you save a radio station, the name of the radio station is not saved on the button, which is normal practice on most radios. instead the frequency of the radio station is saved. e.g [105.5] of cause this is is a minor problem, but I my wold, not a perfect solution.

xylofoejs what is the power consumption? how much current at what voltage?
