I had assumed when I bought my Hyundai Low Radiation monitor that the
Low-rad
refered to ionising radiation, i.e.X-rays from the faceplate, but it seems
not, the low rad refers to electromagnetic radiation. It is certainly
livable with on 136, whereas the other VGA and SVGS monitors I use,

totally

destroy the band for listening. This might be a help for anyone
contemplating Spectrogram listening.

Alan this is very useful information.........

I am contemplating buying a laptop for Spectrogram use (etc) in the field,
and I would be very grateful if people would let me know of their experience
with laptops, especially which ones are quiet and which ones are noisy on
LF........

Also which ones have twelve volt adapters available.....

And for that matter, which ones have truly S.B. compatible sound cards built
in...
