For HF you probadly can change carrier frequency by modifying FPGA code i.e. dividing ck_1356meg signal in the way like generating a subcarrier from external reader's clock.
13.56/2=6.78
13.56/4=3.39
if I have a tag that is working at a custom frequency (probably 3 or 6 MHz) but I am pretty sure that the communication protocol is the same as another 125kHz product, will I be able to use an already implemented 125kHz command (ex. "lf read") changing only the coupling antenna or should I have to write a new code in PM3 ?
