Sorry, that wasn't clear. What I meant to say was : "Most people 
wouldn't dream of trying to interrupt the other station's contest 
transmission before it's finished, because it probably won't work and at 
best there is only about one second to be gained."

In other words, when you are sending a contest exchange using QSK, how 
often does the other station try to interrupt you?

Yes, know the ones, and have used the Jennings and Kilovac relays from 
Allen Bond.

Regardless of my own feelings, the customer is always right - the next 
generation of my Triode Board will have full support for QSK! If the 
user wants QSK, all he will need to provide are the high-speed RF relays 
or PIN switches. Testing for that board (with vacuum relays) is a long 
way down the line, and the next generation of Tetrode Boards will follow 
later.
