On a properly adjusted CT-100, with all the responses (RF, IF, color amp, and the I and Q filters) set up properly, with the infamous bad white peaking coils properly replaced (not easy! ... the specified replacements are wayyyy off) the difference in I and Q colors is not just obvious, its blatant. The screen resolution is much better than the I bandwidth. See the pictures of test patterns I posted years ago, some using exactly correct generator bandwidths.
At times the CT100 at ETF has been good enough.
As I have said before, for just one channel the CT-100 has 81 different adjustments. They all need to be right. This takes either love or paranoia, or both.
My set has the RF for channels 3, 4, 7, 10, 12, and 39 set with love. Other
VHFs are just OK.
