First one needs to know if the short is even there. trying to catch a black cat in a dark room is a difficult task.

Unshorting difficulty depends on the radio.

In a radio like 70 or 90 unless a fin is totally mangled, it is not a problem at all - those are huge caps with huge gaps. Then take a small AA5 set...there is a challenge. a gap is like 0.2mm on either side of a fin.
