Hi,
I think the 270B did have provision for 12-volt operation, and the 270 required some extra thingy. But, yeah, I was surprised how light it was, with built-in supply yet, from its specs. Actually, if I can get close by peaking the receiver, I can probably use the P2000CW to get the rest of the way.
