[Elecraft] Antenna question

Wire a small "grain-of-wheat" incandescent light bulb to the unused antenna 
feed and fire up the transmitter.  If the bulb lights brightly, you need 
some protection.  Admittedly, this is a crude test, but it can point to a 
problem and takes into account all those variables in the calculations.  Try 
all bands and start at low power, otherwise, you may blow the bulb before 
any relative results can be gleaned.
