One of our kind customers asked for the information to add our IF interface to the second IF frequency of an FT-891.
We generally suggest installing it on the first IF frequency because you can have a wider bandwidth, but in some circumstances, you may need a different one. This is the case of a limited-frequency SDR receiver, i.e., an SDR receiver that cannot reach the radio's first IF frequency of 69.450 MHz,.
