One astounding tidbit. Looking at the severe noise (the S/N of a sunlit scene
is like 2:1) I noticed something and measured the frequency response. That's the frequency response looking at the width and shape of a full dark-to-light sharp edge or light-to-dark or stripe test patterns. The 3dB down point.
Its 8 MHz. That's eight megahertz. Eight, 8, e i g h t. And it shows on the high end
Ikegami monitor I'm using. Why would they make such a thing when it was supposed
to feed a transmitter that surely not that wide, nor displays that wide either.
It does demonstrate how sharp iconoscopes can be, such as the talking one in Japan :-)
