Ed,

Right. I've run a few 'stepped power' tests like this with my computerized 
setup and the results were as anticipated.

I hear ya.  Speaking of over-emphasis on the loading coil as the sole 
provider of a beacons effectiveness, do you recall a certain guy a couple of 
years back that announced he was going to set the record for Lowfer range 
via this huge loading coil wound on a fiberglass drum?  Once constructed, 
I'm not even sure the coil had a Q worth bragging about ........ but it WAS 
big.  Of course the one of the nice features of this loop stuff is that the 
radiated power IS directly proportional to the Q of the loop. (Sorry; always 
have to work in a plug for loop antennas into all posts <Gr>)

TGIF...

Bill
