Re: [IRCA] QRM from Lights



Fellas, I think a problem here is that you cannot assume that all power
supplies are identical.  So identical laptops, with "identical" power
supplies can act quite differently.  Perhaps the PSU is manufactured in
batches, or in different factories.  I seem to recall reading the same a
few years back.  I suspect the same can be said for light bulbs, etc etc.
My best advice is to try them first!   73,  Walt
