Hello Lowfers !
>>From noon on Saturday on ,the T&L approaching renderd LF completely useless in 
my area.This morning i conducted a few experiments by altering the ground 
system.I pulled two rolls of "chicken wire" out of the barn and added that to my 
ground system which up to now only consisted of simple wire.The two-foot wide 
mesh has pretty good surface as well as good low DC resistance adding to 
capacitive Rc in parallel.This alteration had only minor change of resonance as 
a result,but the impedance of the system was altered in the magnitude of about 7 
Ohms,that put me in the place to change the generator impedance of my push-pull 
amp,which was quite a thing to do as i use homemade multistranded HF-Litz wires 
on a large core.Got that done and works ok now again,so far this had not much of 
an effect on the HF-current-just a bit.Maybe the improvement in grounding was 
not that much.I will buy more of the stuff next week ,but i see more promissing 
action in adding to the top-hat-which is much more difficult to do-but looks 
like there is no way sneaking around that enterprise to get more current ( and 
more "mileage" )into the antenna.
Maybe some more knowledgeable guys like Dave could put some aspects of that into 
the mail-reflector to give us hints and kinks .
anyways i`ll try to be on tmw around 136.8 /9 .
Everybody have a great weekend !   73 de df2py
