I would like to swap out my 2300h to a 400dr. Would rather not swap out dc power cable. Are the cables the same or is there an adapter for make it possible?
Yes, the cables for both the IC-2300 H and the FTM-400DR are both plasic "T" connectors and so it is possible to swap out the radios without changing the power cables.
The JetStream JTPC-33M 9.5’ "T" Connector Power Cord works quite well.
