Veteran DXers on this list know all about direction-finding with a portable radio's built-in ferrite loopstick antenna. But it occurs to me that some readers might not be familiar with it. So, for the benefit of those unfamiliar with the technique, here is a good, short article explaining how it works: http://radio-timetraveller.blogspot.com/2011/01/unassuming-antenna-ferrite-loopstick.html
The nulling technique off the ends of the antenna works especially well on weak signals like our 1500 mystery (at least the signal is weak in my area). And it's easy to align a compass with the length of a skinny portable to get the bearing. Maybe this will encourage everyone on the list, including those who normally don't post, to give it a try and give us a report! Even "eyeball" estimates of the null direction will help. Using the compass in your phone adds precision. 73s, Fred Schroyer _______________________________________________ IRCA mailing list [email protected] http://montreal.kotalampi.com/mailman/listinfo/irca Opinions expressed in messages on this mailing list are those of the original contributors and do not necessarily reflect the opinion of the IRCA, its editors, publishing staff, or officers For more information: http://www.ircaonline.org To Post a message: [email protected]
