color:#1F497D'>Hi Scott. Thanks for this. It is a bit better. I
am really embarrassed the photo is so bad. It was in the early 70s and I didn’t
think to set up a proper photo even after all the work I had done. The
silver EMI chassis were the actual bus switching and some of the internal DA
amplifiers for the switcher. The Blue Riker chassis have the actual
mixing, keying, and wipe circuits for the switcher. We had sort of the
equivalent of 2 ME’s, one feeding the other. This was the only switcher
at the time and the On Air switching had a cuts only section of the same
electronics, however, PGM 1 and 2 could be put on the air or for production by
the cuts switcher. One person did both on air and production switching
which was mostly easy with occasional double duty. The Blue Riker section
actually replaced two large tube chassis, one was the mixer for dissolves and
the other had the oscillators for wipes. I designed the changeover to
solid state (what a leap in technology) which produced a much cleaner
dissolve. It was great fun and learned lots especially cutting cables
down to the inch to make the color right. I wish I had kept something of
that era but I moved on to other things that I wish I had kept. <o:p></o:p></span></p>

used one of these at KOLN in Lincoln. Originally It was a separate frame
but was integrated with the mixing electronics. Here is a poor photo of
the mixing electronics and switcher rack. We only used the colorizer as a
color background generator but if you fed video into the unit, you could get
more or less a different color at different luminance levels. I
don’t think I saw us use it other than playing around. </span><o:p></o:p></p>

Riker modules in the three chassis were actually copied by the Engineers.
Some modules were bought and others were hand made from the schematics. I
wish I would have kept the schematics because a single module was drawn on one
sheet of paper about 20 feet long. Giant transistors. I had a Riker
sync generator at home but didn’t keep any of it. </span><o:p></o:p></p>
