[Elecraft] DL1 Short Term Ratings

[Rick Dettinger]

I used mine to make the 50 watt adjustments, since my watt meter only  
goes to ten watts, and had no problems.  I limited the key down time  
to a few seconds, just enough to read the voltage.  I made adjustments  
with the key up and then rechecked the voltage on the DL1.  The  
resistors got quite warm but not too hot.  I used clip leads on the  
test points so I only needed enough time to read the meter.
