Hi all,

I have a neat idea. 

Can OP25 be modified to “repeat" an entire spectrum say 851.0125 to 853.9875 with low power so a digital scanner in proximity to the repeater can receive the signal. Specifically can OP25 be able to receive CQPSK (LSM) and convert to C4FM in real time - since scanners have no issues with that modulation. 

thanks!
