Re: LF: T/A on 472kHz WSPR

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!
