Multi-band Band-Pass Filters (BPFs) are used to
prevent cross-band interference between your two
radios during SO2R operation.
The IC-PW2 automatically connects the
multi-band BPF to the non-transmitting radio
according to how you operate between the
transmitting and non-transmitting radio .
This function makes SO2R operation possible with
one IC-PW2 and one multi-band BPF. The
Transmitter lockout function* is built-in to the
IC-PW2 to inhibit transmitting for second radio
when first radio is transmitting.

* This function will be compatible with the IC-7851, 7850,

7610 and 7300.

Of course, if you want to use two multi-band BPFs separately,
you can insert them to each of Rx IN/OUT connectors on the
radio side , or you can insert multi-band BPFs* between the
IC-PW2 and each radio.

* More than 100 W power handling capability required for multi-band BPF.
