I am working with the local power company to find several noise sources. One is to the SE direction from my tower and reads S-9 on the TS-690 (AM mode). What I am wondering is how far out do I need to look for the source. My tower is at 90Ft with a 5EL 10M yagi. We have focused most of our time out to 1/2 to 1 mile. Should we be looking farther for a source that is S-9. Area is semi rural, mostly flat.
When DFing, I am using a 137MHz, 3EL yagi and a HT tuned to 137MHz AM. That seems to work pretty well for 100-200 Ft. The power company rep uses an Ultrasonic detector and needs to be at the base of the pole. If anyone has done lots of this kind of work and has some past experience in appropriate distances, would appreciate some pointers. |
