I have no real recommendations for a meter, and personally use expensive stuff that isn't really necessary. MFJ-Daiwa-Yaesu et al. sell lots of cheaper stuff that should be good enough. If there is no change in meter reading when adjusting RF sensitivity when you're transmitting, that is a problem -- there should be. I don't have a Kenwood hybrid today, but owned several of them over the years and the sensitivity control always had a lot of effect on the output meter reading on all of them.
