How about that.  Only bad thing I heard about the DX is the power
supply can develop problems.
But, how is the Nautel IMD on reduced power have you heard anything?
I've heard most guys much prefer Nautel over Harris but the corporate
bean counters buy Harris.

I'm not sure that would raise it's ugly head in ham use since you won't be processing your audio as much as broadcast stations do, and I probably shouldn't have "muddied the waters" commenting, but at this very instant I'm fighting for the company I work for to not buy a new Harris product, a 3DX-25 transmitter, because the IM goes thru the roof when reduced to low power for night time operation.

I actually got a Harris honcho to admit the 3DX series is not as good as the DX series (which I like) since they removed a bunch of parts like vacuum caps in the output stages to make the thing cheaper to manufacture.
