[ARC5] An "Extra Class" Question:

[john rose]

The First Class and General Commercial test is to license someone to operate, and keep legal, AM and FM stations. I would expect there to be lots of AM questions still on the exam. I remember only one question and that related to the tradition of occasionally reversing the leads to the heaters if DC was being used. The theory was that with the current only going in one direction one end of the heater would deteriorate before the other. Reverse them and even the wear out. True or false? I forget the answer.
