Template:UK System I

Template documentation

This is a calculator for the vision carrier frequencies of the UK's now-obsolete 625-line PAL analogue TV system.

Usage

Input parameter

ch is the channel (must be between 21 and 69). 69 was hardly (if ever) used, but was a valid channel in Band V.

So: {{UK System I|ch=23}} generates "487.25 MHz" (one of the Band IV frequencies).
    {{UK System I|ch=59}} generates "775.25 MHz" (one of the Band V frequencies).
