I put a dab of White-Out between the pot adjustment screw and the pot body prior to pulling the DR7. This way, a quick look at the White-Out tells if the pot adjustment has been moved............Larry, .....N1UKX
Missing from your very instructive observations is the caution to be very aware of the pots on the DC-DC converter board, it is horribly easy to bump them when removing/installing the DR7. Even the slightest touch will knock one or more of these pots out of adjustment, and as more than one of us had found out, they are critical.
