Lesson 34: General Class Exam Course G0A

Here is lesson 34!  This lesson primarily covers RF safety and Maximum Permissible Exposure (MPE) limits.  RF energy can heat and damage bodily tissue.  None of the material in this section is much of a stretch and most of the answers fall within "common sense."  One thing I will recommend is to do a quick scan of the FCC OET Bulletin 65 which covers RF exposure limits and RF safety.

There is one question that is a little out of the ordinary.  When multiple transmitters are operating at a single site, the transmitters which are contributing more that 5% of the MPE limit are the ones responsible for ensuring RF safety compliance.  The actual way this is determined is a little more complex than what the question seems to be asking.  It is probably best just to memorize this one.

One more lesson to go!
