Either a single or redundant SDXs could provide switching internally. If there is an all-analog path, there must be an additional analog switch. The number of receivers and tranmitters has to be decided first. I think that 2 U receivers and 2 V transmitters are required. If the ACP is LS2/C or C/X then add 1 L receiver and 1 S1 transmitter.

Folks,
I believe that I read somewhere recently (although I can't seem to find it now) that the concept of an IF switching matrix has been discounted. I don't know what the reason for this was, however on the basis that it seems clear that no-one is sure what bands may or may not be useable or available over the next few years, is it worth re-addressing this for feasibility?
