Random thoughts:

1. Does moving the computer cabling around make any difference?

2. Does unplugging the sound card connection to the receiver help? This
might indicate that some common-mode RF choking in that audio cable would be
the solution.

3. Does turning the monitor off help? I sometimes had to do that during
"Hifer" operation last summer. It's a pain, but if you are dealing with
QRSS60 and screen captures, it may not be such a big deal. Another thought
for the financially gifted (whoops, forgot that you're in broadcasting...)
would be an LCD monitor. They don't generate the big E and H fields that the
CRT monitors do.

4. If the computer is networked, does pulling the network cable help? You
might be able to do without it for the duration.

5. Describe your antenna setup.
