Assuming you want only more power that the nuc offers, I would consider piping the rf out of the msf into the nuc pa leaving the msf rx/tx repeat path intact. It would involve matching the rf power levels out/in and the pa control line to the msf pa control functioning. The reverse is what i plan for a quantar cage to msf vhf 350 watt pa (quantro idea). Could be entertaining. . bill w4oo .
