With a little preparation that can be done without a phasor 
modification. I've gone in during the experimental period with a 
bridge, manufactured the needed jumpers, and recorded the crank 
positions (and all other necessary information) to run non-D on 
either tower (or, at one station, either of two selected towers in a 
5-tower array). A little work in advance makes it possible to set up 
non-D for work on any tower.

That came in handy a few years ago when a storm brought down one of 
two towers at a client station. I was able to get them back on 
quickly at 25% of their nominal power non-D (which is exactly what we 
were given in the subsequent STA).
