The capability exists in the hardware for full duplex, but you will want to run split-IF. You will not want to do this on the same antenna connector (we won't allow you to do this). > Will a panadapter on this slice show the transmit > signal as 0dbm? > I think you are asking about tx/rx on the same connector at the same time.

The hardware can support around 60MHz of bandwidth. I suspect it would be more trouble than it is worth to produce multiple carriers, send them out one port, use a multi-plexer to split these into individual signals and handle all the keying logic.

The receive side of what you are suggesting could be done external to the radio. The transmit side would require multiple transmit slices in the radio and a change to how we do transmitting. It is possible, but I suspect there are so few people that would use this that it's just not practical. > > > > _______________________________________________ > Flexedge mailing list > [email protected] > http://mail.flex-radio.biz/mailman/listinfo/flexedge_flex-radio.biz > This is the FlexRadio Systems e-mail Reflector called FlexEdge.
