> I use a Navy Surplus Bird Professional Broadcast Dummy Load with a built 
> in watt meter rated at 1KW forever.  I use it frequently to tweak the 
> Gates BC-500T for 160 meters or the Bauer 707 for 75 meters.

> There are numerous surplus houses around the country that sell them and 
> depending on your pocket book can range from $250 to $1,500.  I paid 
> $289.00 for mine last year and it runs cool when I put either one of the 
> Big Boxes into it.

> Email me directly and I'll send you a digital photo, P/N and the name of
