I have a problem with TRlog connections to MFJ-434 Voice Keyer. My LPT =
port of computer has negative level of voltage (-4v) and when I push =
bottoms F1-F4 than the level drops to 0v. For normal function of =
interface from LPT to MFJ-434 I need positive voltage( from 0v to +4v). =
How I can do it?
Anyone know this problem?
