RE>TopBand: Beverage resistors 1/10/97
Hi Tree, yes the transformer provides a low impedance path for DC, but the
reason
why termination resistors blow open is due to the 2 ground rods at each end of
the
beverage that samples ground sheet currents. These currents are induced by
lightning,
etc. There's a potential difference that correspondes to the radius
surrounding
the area lightning strikes. Hope this information solves the mystery .

Well, if switching the beverage to ground solves the static buildup
that blows up termination resistors, perhaps an easier way is to
use a RF choke to provide a low impedance path for the DC.
However, don't most people's impedance matching transformmer already
provide a low resistance DC path to ground? If so, it seems that would
suggest that the damage is being done from an RF source (like your
transmitted signal?).
Or am I missing something (probably)...
Worked VK3IO this morning - the polar route has been totally shut
off by the high K numbers. Hope things settle for the weekend.
Did work HR/K9BG for #141 however. The number of unworked North American
countries fell by two this week (TI9CF is the other one). There aren't
many left for me: CY9 (hi Mike), OX, HP (!), some of the HK0 rocks,
and PJ7 (!!!!!!!). Also KP1 and KP5, but I am not sure they really
exist.
Trying my 3rd attempt for a YS1ZV QSL via KB5IPQ. I am told this route
really works, but I am having my doubts.
Maybe he is upset about my carpet bagging to his state during SS CW.
