Default Headphone hum on transmit cw

I have an issue on 40 meters from my tentec scout 555. After the rig is
tuned (mfj 901b) and I tx cw, I get an AC hum in my headphones on every key
down. This doesn't happen when my audio comes from the rig. I am using an
alpha delta loaded antenna in the attic and it is almost certainly putting
the tuner to a test. Is there something I can do to alleviate this problem?

Thanks
