I'm looking for advice on locating overhead power line RFI that is contributing to the noise level here at my qth located in a 50 yr old (read original distribution system) city neighborhood. Last time I dealt with power line RFI was easy as I was out in the country with no neighbors for a mile so tromping up and down the power line with my trusty AM pocket portable was easy work to find the offending poles. AEP, the power company, here and at the old qth were very cooperative and fixed every issue I told them for approximately one mile around improving Now living in a Texas neighborhood I am afraid of gun fire and possible police harassment for walking the alleyways trying to find RFI besides some of the alleys are fenced off illegally. Is an MFJ-856 the way to go or is there a more economical effective way to locate the poles that noise is coming from? In the city what is a reasonable expectation regarding the distance from my qth to noisy poles that the power company should be expected to take action? a block, a mile, ??. The community hospital is one block away from my qth and there is something inside one of the outbuildings, not a treatment area, that obliterates my AM vehicle radio reception worse than any power line when I drive besides the building. Are hospitals required to take steps to reduce RFI to amateur radio installations? Besides moving back to the country which I dearly miss but unfortunately can not do, any advice from those who have dealt with RFI "in town" would be appreciated.
