Trying to improve my reception from Chicago with baseball season
approaching. I'm about 100 miles sse in Indiana. I ran about 75' RG-6 from
my radio across the attic and outdoors to a tree. I had maybe 10 extra
feet of coax so I wrapped it around the tree. I strung about 50' of #9
steel wire between 2 trees going east/west about 15' above ground and
attached the copper conductor to it. I terminated the coax shield at the
tree with a ground rod. At the radio I attached the shield to the ground
terminal and the center cu conductor to the other am external antenna
terminal.
It greatly improved my reception I get all the major Chicago sports
channels, but the one I was most interested in 670 is the worst. What all
did I do wrong and what can I do to improve 670?

I wouldn't bother with the braid on the coax, use it as one long wire!
50feet is far too short, it's not resonant, you would need about 3 times
that.
You could also try loading the aerial with a large coil of wire or use an
ATU.
Be aware an ATU doesn't match the antenna as such, it doesn't make it
resonant, it only acts to make the reciever see 50 ohms. The aerial will
still remain unresonant!
Other than that, go to www.reciva.com and get the station via the Internet.
