Hello all,
I know Frank/WB2BXO wrote about a keying problem and many people replied.
I had been in the same trouble since CT was revised than Ver 9.27.
But this problem has just been resolved right now.
My interface was wrong !!
The base of NPN transistor was connected to Pin 13 through a 1K resistor.
I changed Pin from 13 to 17, and keying became to work with no problem.
Why did I make such a mistake ?
The manual of CT says that Pin 17 is "SLCT". But as far as I know, "SLCT"
is Pin 13, and Pin 17 is "SLIN". So I connected the base to Pin 13.
The older version of CT than 9.27 and many other logging program can
work well with this interface, and I could not noticed the mistake.
Although I don't know the diagram of W1WEF interface, I advise you to
check your interface again.
Tks, de JH8KYU
