George, I suggest you call TT tomorrow AM. Talk to Paul Clinton. Ask him about the keyer issue. I beleive he will be honest with you. Also, IF there is a general problem (All OII's) TT will fix it. I am sure of that. It is too bif=g of a 'feature' to allow a problem to exist. My OII should be here end on January(Ihope) so I will be testing it soon! 73, L:ee, KC9CDT
