Going back to a question posed at the outset about relay life... The 
reflector is not full of people saying that QSK trashes their relays. On 
the other hand, my mental arithmetic (far from reliable these days) 
comes up with an estimate of 120-150k operations for a heavy duty 
contest weekend - a sizeable percentage of expected lifetime. Ensuring 
cold switching will presumably help, but mechanical failure is going to 
be a factor at some point.
