[Elecraft] Dummy loads for dummies

[David Olean]

It always pays to keep your eyes open.  The local (and only ) surplus 
store here has a pile of heat sinks that look just great for a 250 watt 
solid state PA. The good part is that they also have a pair of SMA 
connectors, PC boards, and associated flanged 50 ohm resistor good for 
several hundred watts. I think I paid $15 for one, so I got two DC to 
2.4 GHz dummy loads for $7.50 each. It is easy to modify them for what 
ever connector you want. Jim is right, but always bring a pocket ohm 
meter! heh heh.
