[Lowfer] EAR on e-probe and EWE

    Thanks JB.  I think I finally found the right spot in the yard for the 
e-probe.  I had it about 20ft closer to the house and up 12ft or so and that 
although it worked there, it never did work exceptionally well.  Between 
having some mid-band attenuation, up higher, and farther from my house 
seemed to make a big difference.  It was overloading pretty badly on the AM 
band at the current location until I put the LC shunt across the e-probe 
input.  Likely only 30 dB or so of reject in mid-band AM, but that seems to 
have tamed the J310...the e-probe seems to work better in this location than 
at the end of my back yard, although other power line coupling could have 
been an issue there.
