[SOC] A question for you

[Randel Livingood]

I am beating my brains out trying to figure out Effective Radiated Power.  The formula appears to be:

ERP= Transmitter power X 10 (+- antenna gain/10)

the example given is 200 w transmitter output with an overall gain of 2db. So if my thinking is correct it would look something like this:

200x10x 2/10

The answer given is that the output is 317 watts.  Can anybody help me see the light?
