137 kHz Beacon on the Air

Date : 27 / 08 / 2009
Author : Peter Young - VK3MV

Well known Amateur Radio Magazine author and experimenter, Drew Diamond, VK3XU, is operating a CW beacon on 137.4 kHz every Saturday and Sunday afternoons and evening. Drew has activated a 50 Watt transmitter (pictured right) into an inverted wire antenna from his Wonga Park QTH. He would like to receiver signal reports, that can be sent to his email address: vk3xu  wia.org.au providing date, time, signal strength and grid locator (eb QF22ML). Due to the very low antenna efficiencies at this frequency, Drew estimates his effective radiated power is 6 milliWatts. His signal has been heard in Melbourne, Sale and Sydney.
