The rules are, you have to protect everything that got there before you
So an application in 2018 for a minor mod to 1510 in Boston has to protect
WRNJ as it now exists, as well as WLAC and WWSM in Pennsylvania and the
phantom CJRS that hasn't existed in Sherbrooke for 20+ years but is still
notified internationally to the US.
The one advantage Ed has now that didn't exist even a year ago is that the
"ratchet rule" has been repealed. That rule, when it was in effect,
required an AM minor mod to show a reduction in total interference, which
in practice meant it was very hard to move an older AM without being forced
to take a power/coverage loss.
Does that help answer the question?
