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
