Hi all,
Sorry, but this is not about cheating :.)
When setting up for the 10m contest, I discovered RF is getting into my
laptop/keying line when running power. I'm using a Dell laptop with 2
USB to COM adapters - one for the radio and one for CW. As I increase
power above 200W, the CW starts to slur, then goes solid keydown. As I
lower the power it comes back without skipping a beat. I tried
disconnecting everything going in and out of the laptop except the CW
serial port and no change. I tried some ferrites on the cable and no
difference. I've never had any RF problems before (but used a desktop
computer in the past), everything is well-grounded, and the antenna is
about 200 ft from the shack. It's fine on all other bands running full
power. Any ideas?
Tnx,
Barry W2UP
