[CQ-Contest] Interlock hardware ???

[Jamie WW3S]

only mentioned it because the specs on the EA4TX website mention around 300 
ms reaction time.....I "think" that’s probably enough, just wondered what 
others thought....

The output power risetime (key closure to output power appearance at ANT 
output) of a typical transmitter is in the 1-5 millisecond range.
The reaction time is much shorter than a millisecond, so there will be no 
two signals on the air at the same time.
When thinking about this reaction time, think it is as long (short) as a 
single morse code dot sent at over four thousand WPM!

interesting to read the reaction times, and wondering , what is an 
acceptable reaction time? In reading the specs, it appears it is indeed 
possible to have two (or more) signals on the air at a time, even if it is 
for fractions of a second.....
