Re: 20 Watt QRPLabs Dummy Load for Sale?

OK, your heatsink sounded larger than pocket-size. The resistor spec sheets show how quickly they derate with temperature, so there might be little to gain using a higher nominal power resistor. My QRP load here uses a 100-watt resistor but quickly gets too hot to touch with 25 watts in.
