Thanks, Greg - that's all we need to know for the present.

When Wayne revisits this feature, a reasonable goal would be 30ms, which 
would accommodate the vast majority of HF amplifiers. (The FT-1000 
series have the same adjustment range.)

Whatever the transceiver/amplifier combination, the way to adjust the 
transceiver's key-down delay is to use a low level of drive, and start 
at the maximum delay the transceiver can provide. Progressively shorten 
the delay until severe clicks begin to appear at key-down, because RF is 
arriving before the relay contacts have fully settled. Then increase the 
delay to a safe value at which no clicks appear, even at full power.
