Scott, The last 1100S service manual went for over $350.00 on eBay a few months ago. Now all you see is CD copies of the manual. I have a 1100S I can't get fixed because I don't have a decent manual, tried the CD version but worthless to try and use, at least the one I have. The manual is on the repeater builder website I think. Paul

What is the difference between an IFR 1000S and an IFR 1100S service monitor? I know that they were sold to the military as the AN/GRM-114 and AN/GRM-114A but what is the difference between the two. The reason I ask is that I can't find a manual for the 1100S but sort of have for the 1000S----lousy CD with unreadable schematics---but it looks to be pretty much on track for the 1100S. And while we are on the subject---I'd like to hear your comments concerning these units.
