[Elecraft] RFI from computer

[Monty Shultes]

Barry -
The interference may be coming from the LCD.  Can you reduce the brightness of the display?
Also check the power supply - try putting beads on the leads.  It could be a noisy switching supply.

If, as Jeff suggested, it's Ethernet noise, you could use a USB wireless adapter if the laptop does not already have a wireless network feature.
