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."

OK Clemens it seem most easy to have 10W ERP on 475 KHz
comparatively on
137 KHz hi!
