Yes when I use my ICOM R75 or Grundig Sat. 800. But not for all other radio. Sometimes the telescopic antenna works better! I've seen this word before what is null? BTW I have a friend who has the book EASY-UP ANTENNAS FOR RADIO LISTENERS AND HAMS, EDWARD M NOLL. Maybe I'll take a look at it. All antennas receive better in some directions and worse in others. The good directions are ''lobes'' the bad directions are ''nulls''. A loop antenna has killer nulls perpundicular to the plane of the coils. If you are trying to hear on a channel with more than one station you can steer the null toward one of the stations and then just hear the other one. This is the #1 advantage of a loop antenna, IMHO. |

I read your message. If you get this message on time, I am getting a
station that sound like Indian music. Around Bettween 7.15 and 7.2 am. Sorry but I am using my Hammarlund 170. The dial is hard to read.

Hey: It was one of those moments when a swl all of the sudden find
something on the airwaves and gets excited. By the time I would of connected my R75, which was put away, the broadcast could of disappeared. Considering the effort, it was only something to share.
