===Introduction===

All versions of the Portsdown Transmitter have a Test Card transmit function and this is based on the Test Card F. The Portsdown 4 has the capability to select one of 12 Test Cards for use.

===Test Card Selection===

On Menu 3, there is a "Select Test Card" Button. This brings up a screen with 12 available Test Cards. Five of these are in-built cards, but 7 are easily customised for individual use. The in-built cards are shown here:

[[File:tcfm.jpg|72px]] [[File:tccw16.jpg|72px]] [[File:pm5544.jpg|72px]] [[File:75cb.jpg|72px]] [[File:11g.jpg|72px]]

Widescreen versions of these cards are also included. These can be transmitted by slecting Format: 16:9 or 720p (rather than 4:3) on Menu 1.

===Callsign Caption===

The Callsign caption is automatically displayed on Test Card F, but is turned off for the other cards as it is unlikely to be in the right position, or rendered at the correct size. The Caption can be turned on or off from the Test Card menu, or from the button on Menu 1.
