[Lowfer] WA down for the count

Sat, 02 Feb 2002 22:18:54 -0500

WA is back on the air for the moment. The input current is down about 2X, 
after retuning, as the result of the higner Rac in the single #12 upper wire 
compared to the pipe. Theres a 4x#12 run for the lower leg that was not 
changed. No adjustment on the turns ratio of the impedence step-down 
transformer has been made at this time.

What is very interesting is the measured signal strength, at my test 
location 1.7mi to the west, is almost as strong as before!! When I change 
the truns ratio in a few minutes to make the input power = 1w the signal 
strength will be twice as strong as before. What is likely to be the reason 
for this is the average height of the loop. Still 50ft at the top (FCC take 
note) but the inverted 'v' shape of the pipe loop is now a straight line 
with the #12 wire installation. The lower portion now has a 'V' shape and I 
think this could be reducing the ground losses as well.

WA will be down for the next hour to allow the transformer change in the 
comfort of the warm shop. Some retuning will be needed too. Get those 
goggles ready!
