No doubt a lot of the noise was directly radiating into your wire. In that case, a choke is just a paperweight.

Hi Colin,
Yes, I thought of a CM choke as well, and tried one (with plenty of
inductance to work well down at LF)--no discernible change in the AC
hum! But the longwire is all down, supports removed, wire rolled up, so
I don't ever plan to try that failed experiment again. :)
73,
Steve

It was worth a try as I had no idea how much, if any, a parallel powerline might couple to the longwire. Now I know! I'll eventually try another location that's much farther away from the powerline and hope for better results.
