Put iron pipe on the ground with the feedlines running inside. That

Hi Rick,

Good  to hear from you. This current shift thing (and for me, a resonant 
freq shift) took another turn toward the unusual,

yesterday, when the resonant freq changed back to where is was when I 
first turned the rig on three days a go.

Also the input current to the final, at resonance, went back up to where 
it was..... and is holding fast from

this morning's value to tonight's, even though there was a freeze-up 
after 4:00pm. Might be something weird

going on in the final so it's lucky I brought up the scope this trip. 
I'm hoping the problem isn't with the

loop wire, its self, and the insulation is worn where it contacts a tree 
limb. This isn't supposed to make

much difference at this low power. Another possibility is that the coax 
leading to the final is  damaged.

I must have run over it a 100 times this summer with the tractor (having 
chains on all tires) and a couple

of 1000 pounds of load in the bucket. The coax to the receiving antenna 
suffered the same abuse and a continuity check shows

that it is open.

I'll keep you posted.

Bill
