Hi again Larry.
Yes, all this brings back old memories. I quit the TV repair
business back in 1986 (I Think). Anyway started doing PC work and now I
wish I could sometimes just run away and play with my toes in sand. HIHI

Yep I agree on all this. Actually I and Q as I remember was a Hazelteen
patent that RCA had to buy. the R-Y B-Y detector was developed by RCA
avoid the license fees from Hazelteen.
Growing up into color TV near RCA's plants and Sarnoff was ben a bif
help to me on
early undestanding (college years0 of how color worked.
I actually worked with RCA Sarnoff while DE at NJ Network on their first
system which used yet another subcarrier in the imaginary plane at about
3 mhz to
add the side panels for the wide screen.
Amazing math tricks are used in all this.
Kepp up the good work.
