Acoustically coupled & way over driven, has what I hope is echo on 
trailing edges.  Presumably from another receiver?

There looks to variation in some element lengths & inter-element spacing 
(bother either shortened or lengthened by about 10 ms?) before N4LQ 
asserts PTT by pressing the front panel XMIT button.  After that, no 
variations & consistent dot/dot-space/dash ratio near 1:1:2.5.

Radio following keying I would have thought is basic stuff & 45 wpm 
isn't really all that fast.

This must be something that was introduced after new/old QSK selection, 
as would have expected somebody to have noticed at the time, as folks 
then were looking at key closure & transmitted RF with 'scope, also with 
an eye on receiver recovery.
