DL1 Short Term Ratings

[Neal]

Has anyone determined what the DL1 is capable of for a short time (say 10 sec) in excess of 20W?

Besides the power dissipation, one would  also have to consider the PRV of the diode.  It looks like 50W would stay within the diode's PRV rating.

Tnx, Neal WA6OCP

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.
