You think CW is dead ... try tuning the Bands during a CW Contest. And, just wait till the P5 shows up on CW, the pile-ups will be of Biblical proportion. There will be a new Aurora in the sky. 73, D

IIRC, Eimac never made Graphite 3-500's, if I am wrong, someone will correct me. The Graphite Anode, being of larger mass, and who knows what's in them, may need those precautions. Saying that, I con
