Do long cables affect PAL and SECAM signals?

Long co-axial cables or microwave links can cause amplitude and phase variations, which do not affect SECAM signals. However, PAL and SECAM are just standards for the color sub carrier, used in conjunction with ITU television broadcast systems for the base monochrome signals, identified with letters such as M, B/G, D/K, and L.

What is the speed of a SECAM video recorder?

The VHS specification for “native” SECAM recording specifies that they be divided by 4 on recording to give sub carriers of approximately 1.1 MHz and 1.06 MHz, and multiplied by 4 on playback. A true dual-standard PAL and SECAM video recorder therefore requires two color processing circuits, adding to complexity and expense.
