The power strip and the cable length combine to cause the high drop. The 
rig should always be powered directly from the power supply, and with 
the shortest practical cable. There are several vendors who sell 
PowerPole connector parts. All that's needed to install them are a 
soldering iron, diagonal cutters, and decent needlenose pliers. It's not 
too difficult to make a Y-cable so that you can feed a single PSU to 
both the radio and the power strip.
