I am impressed with the H840CK15. It has 4 IF stages and appears to demodulate the chroma on the R-Y and B-Y axes. This means early on it appeared to be the sensible way forward.

However I question the written statement that the placement of the color subcarrier at the 50% point is on the curve depicted.

Although it is stated that the the color subcarrier (42.17MHz) is at the 50% point on the curve, it looks to me 42.17MHz is at the 100% point. Perhaps teh 50% is instead 41.70MHz?
