I've been working with the rtl-sdr v3 for a few weeks now. I am receiving interference from a local AM broadcast virtually everywhere I tune across the sw bands. The station transmitter is about 2 miles from me and transmits with low power, especially at night on 1450. I have coax going out of the house to a wire that connects to a down spout about three stories tall running up to the gutters across the eaves of the house. The gutter runs more or less north-south and the 1450 transmitter is to the east. Any ideas how I can eliminate this problem?
