After searching and playing with my Winlink (I know, different from Pactor) I see that there needs to be an authorized IP address and Port setting of 8772. If you have the right port but not connecting, confirm your IP address or reenter it. I am sure you have done that a million times, but a misplaced number or punctuation will put a kibosh on your connection attempts. Also, will current
band condition and time-of-day support you connection?
