I have just changed the computer I use for running ON7YD's QRS program to key my transmitter. Both old and new computers run WIN98. The old one worked fine with QRS, but the new one behaves strangely. I use pin 3 on the printer port and it measures +5V on key down and 0V on key up (as expected) but after a few seconds of key up it returns to +5V again. The idle state is +5V and it always returns to this state after a few seconds. Any ideas? Mike, G3XDV ========== |
