If you can't hear it, and don't notice a detrimental rise in the noise 
floor, using other methods, don't worry about it!

I monitor aircraft daily, and have no issues with HT's, with the squelch 
off, more than a foot or so away from several widescreen monitors.

I DO have a 20" Dell monitor that wiped out all of HF, and lower VHF, 
through dirt, concrete, and steel, affecting an antenna 135' away.  I 
put a few turns in the power supply, and audio cable (the worst), and 
cannot detect noise more than 3" away.

In the end, if you aren't doing all your work within 18", and can't 
detect anything further, why worry?
