For the FT1000MP family, you can hook the noise canceler to the
auxiliary RX ANT port and let the rig do the T/R switching for you. By
selecting the primary (A/B) antenna, always used for TX, and either the
primary antenna or the aux RX antenna, you can also switch the noise
canceling unit out of line. Details on the www.va3cr.net site. Thanks
to Bob, N6TV and Ron, W4LDE for the information.
