I've just received the specification for a new TV system that we are
install. The document is dated December 2005. Here are some extracts:
"The distribution system shall conform technically to the
to the recommendations or the Ministry of Posts and Telecommunications
"The gain of the amplifiers shall be such that the signal levels . . .
be not less that 750 microvolts measured as root mean square peak
level across 75 ohms."
"Amplifiers to be fully transistorised type."
"The amplifiers . . . must have an adequate interprogramme
"The aerials shall be designed to give adequate band width on the 405
and 625 line standard TV channels and on Band II for unbalanced."
I would tell a company like that to get themselves into the 21st century
fast, also tell them to f*ck off as they are obviously about as much use
as a chocolate fire guard.
