	Oh, indeed I do. ;-) I have an R1011B myself. I've been using them, in one location or another, since my tenure with Motorola back in the late 80's/early 90's.

	They are outstanding units. Very well built, durable as blazes, and fully shielded and bypassed so they can work reliably in the presence of strong RF fields (they were made for servicing mobile 2-way radio products).

	They have, however, got one big drawback: They are very complex, electronically speaking. Motorola used a bizarre hybrid of linear and SMPS technology in the thing's design. If you ever have to service yours, best to have, among other things, an O-scope and electronic load handy. 

	The good news is that, if you get one that's working (fairly likely, as they're hard to kill), chances are good that it will stay in that condition.

	The manual for them is not that thick, but does have a fair number of pages. You can order one for less than $25 directly from Motorola. Alternatively, if you just need the specs and/or the schematic, I may be able to scan it in for you.

	Let me know. And good grab!
