When we resided in the large apartment complex in Lovaland, Colorado, I
could not receive an AM station (KCOL) in Fort Collins (transmitter, maybe
10-miles distant) due to RFI throughout the complex. It was so bad, I
could detect the RFI on a crystal set using the downspout from the top and
third floor of the complex. I tried an mag. loop in an effort to make a
few contacts. Still, too much RFI. Have a read of the last (and a bit
long) paragraph of my QRZ page. Its all real.
