For those of you using optocouplers in your radio keying lines,
have you noticed that the speed of the device makes any difference?
The optocouplers I've come across are 5 microsecond switching time.
I now understand that there are faster ones out there (2 uS.)
Has anyone noticed if the switching speed makes any real difference?
What is the typical switching speed of a 2N22xx transistor?
Thanks again,
