The 2012 Hifer season proved to be a record breaking year. Many US Hifers(high frequency experimental radio) running milliwatts of power and modest antennas made it into Austrailia thanks to Steve, VK2XV’s grabber. EH in CT was the first to be copied and later RY in Maine broke the record. Shortly after EH broke that record being copied on VK7ZL’s grabber in Tasmania.

Well sitting in the dark, without power, on Halloween night, around 21:00 to 21:30 hrs local, quite bored , I dug up the protoype L-600S and gave a listen. At first I heard the switcher in the head lamp and my watch ticking 3′ away. The 60 Hz crud was very low and I could hear the clanking bottles, that is “tweeks” very strong with the loop facing East and West. At times,I could hear the alternator whine of the cars driving by at about 60′ in front of my home. At a North – South loop direction, a unique frying “hiss” was noted.
