As it happens, I had to put a 50 Ohm fixed resistor in series with the 100 Ohm pot this time as I was running out of room trying to adjust nulls. More wire in the antenna than I'm used to? 180' DKAZ is BIG and putting it up in the wind is kind of a challenge. BTW, I was using 670 KBOI and 780 KKOH for skywave nulls and, thanks to the 'skewy' cyclone fence next door, also did pretty well in KXTG on 750 from Portland. _______________________________________________ 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]
