[Elecraft] Don't have a 50W dummy load

[Brian]

Excellent advice Don.  I bought a 100w dummy load kit from OHR. It's 
called the RFL-100 and it's about $40, comes in a very nice cabinet, and 
takes less than an hour to build.  It has come in handy more times than 
I can count.

Oak Hills has some good goods.
