I read on this forum that there is about 15
milliseconds delay between the transition of the 8R
line from receive to transmit (and hence of the key
out lines in the KPA100 and K60XV) and the beginning
of RF output. I have a couple of questions with
respect to this delay:
(1) Does this apply on bo
Perhaps you remember this:

I measured this a couple of years ago and put the info in my notebook.
As you mention, 8R transitions 15 ms before rf output. It doesn't
transition back again until 5 ms after rf has stopped. The timing
is completely independent of the t-r value set in the primary menu. I
tried it
Steve,
Well here are the measurements you were asking for (curiosity got the
best of me and I decided to throw a test set up together and see what I
see before going on vacation).
