Myles,
Yes, those are very nice lamps, although I do not presently have any in my
house. (If I am not mistaken, Ottlights are those used by the appraisers
on "Antiques Roadshow". They have excellent color balance and uniformity
of illumination.) A few questions:
1. Since it is a desk light, I presume it is plugged into the wall socket.
Is it the same socket from which your rig draws power?
2. What is "walking away"? Do you mean that you take and move the lamp
further away from the rig?
3. RFI coupling from an RFI source into the cabinet of a rig is somewhat
rare (as mentioned on this reflector many times in the past). So, is the
lamp near an antenna or tuner used with the rig? If so, what's the
separation distance between the lamp and antenna or tuner?
Thanks in advance for your answers. This will help the rest of us get a
handle on just what might be happening.
73, Dale
