![]() During my working days in a shortwave relay station, we used to go out to the field to clear off the hanging charred claws on the feeder lines. The birds standing on the feeder line did not know when we will switch on the 250kw transmitters and burnt to death instantly, leaving behind the claws hanging on the line. weng -9M2FO- Our shortwave transmission lines carried mostly 50 KW and 100 KW signals, usually at near 100% modulation of the amplitude variety. Our carriers were between 6 MHz and 16 MHz, sometimes higher or lower, depending on target, time of day, or season. When a bird landed on a transmission line wire he mostly evaporated without a trace except for his claws gripping the wire. There was a puff of smoke and steam during the instantaneous event. The transmitter usually had no visible response. It kept right on pumping out the megacycles. Our transmission lines were coated with bird claws. Best regards, Richard Harrison, KB5WZI |
