At one time, I had a Comet wattmeter rated for 2 KW, and when operting RTTY, after about 15 seconds keydown at 1 KW, the needle started dropping off. Thought my amp was losing power until I tried another wattmeter. Barry, W2UP-- Barry Kutner, W2UP Internet: w2up at mindspring.com Newtown, PA Frankford Radio Club
