Duh... I did it again. I accidentally left the bench coaxial switch looking into the sig gen/attenuator, and keyed about 100w from a Kenwood TS-530 in CW mode into it (instead of switching to the dummy load. ZAP! The attenuator let the magic smoke out. Its repaired now, but check out the damage to the 1st 20dB pad :-) ...
I have a step attenuator on my bench, between one of the signal generators and a rotary switch. The switch selects a dummy load, sig gen, and outside antenna, and presents that to the radio thats on the workbench. I had a brain fart, left it in sig gen mode, and laid 100w on it :-) . Magic smoke escaped! Oh well, a little work, and it's back in service...
