[Elecraft] K3 TX delay

[W5UXH]

I am under the impression that the TX DLY setting of "8 msecs" does not
actually produce an 8 msec delay between KEY OUT going low and start of RF. 
In non-QRQ mode I think it is on the order of 15 to 17 msecs.  The delay
does increase approximately 1 msec for each unit increase in TX DLY.

In QRQ mode, I measure the delay between 4 and 5 msecs when TX DLY is set to
8, and I believe it does not increase when TX DLY is increased.
