You might do a little investigating to see if there really is a loud station blocking your receiver before you invest in something you may not need. ?The first thing I would try is just receiving off a long wire stuffed into the antenna port (NO TRANSMITTING!).? You¡¯ll get a better understanding if the receiver is the problem that way.
I am about 14 miles away.? I am in a densely?populated area with a large apartment group next to our condo community, so I suspect there is probably a huge number of different electronic devices and there could be spurious emissions from them.
