Re: replacing the RX filter with a balun on the c139

You can find a picture of what I'm looking at here: http://thre.at/c139/c139rxfilters.jpg . I've placed the c139 schematics in that directory as well, http://thre.at/c139 .

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.
