[Lowfer] FDIM at Dayton

[Paul Daulton]

Lots of audio bricks( like car stereo boom boxes) go up to 400khz or more. I 
use a hillbilly defibrilator( B&D jump start) for power, I think those have 
7 amphr battery.
Should be able to send enough power through rg-6 cable to power it at 80 w. 
Irf 530 power mosfet is good for about 35 watts as single, two should give 
70watts. shouldnt take more than 3 watts to drive.

Remote tx for 600 meters would be good project, have to give that more 
thought.
