As a side note, you should use the quadband branch (soon to be merged) and  
replace (in board/compal/rffe_dualband.c)

uint32_t rffe_get_rx_ports(void)
{
return (1 << PORT_LO) | (1 << PORT_DCS1800);
}

by

uint32_t rffe_get_rx_ports(void)
{
return (1 << PORT_LO) | (1 << PORT_PCS1900);
}

because the hi band input is plugged to the PCS port of rita and not DCS  
port.

Cheers,

Sylvain
