I'm using Beezley's coil.exe and your figures are correct. Coil.exe 
disappeared from the web recently and no one can seem to contact Brian 
Beezley to purchase a copy. The rumor is that he is irritated with people 
pirating his software. I have ordered another coil program and will evaluate 
it.

thanks for the info on ERP. I didn't realize lowfer ERP was so low. Just 
makes for a greater challenge. I just subscribed to the Lowdown and haven't 
seen Bill's article on loops. Maybe loops are the way to go. I just ran a 
simulation of a one-turn 1.7 MHz loop made of 1 inch copper. 2 meters by 3 
meters and the efficiency is 3%. A simulation of a two-turn loop showed even 
better efficiency. I have never tried a loop before because of the narrow 
bandwidth. But, for medfer use the bandwidth is no problem.
