When the public radio of Armenia
was still active on mediumwave, they received a letter from a
person claiming to have heard their station in some very far
away place. The letter contained a question to Radio Yerevan: "What is your radiated
power?"
Answer: "We know our traansmitter
power (P kilowatts), and measured our antenna resistance (R
ohms) and our antenna's effective height (H meters). Using
standard antenna engineering formulas based on Maxwell's
equations, we calculated an ERP of X kilowatts. However we live under a socialist law
that radio stations can never have more than one watt ERP. So
we have to conclude that Maxwell's equations are in error, and
our ERP is exactly 1 Watt, as prescribed by law."
