Portsdown transmitter FAQ

• How do I turn the transmitter off in Touchscreen mode?

In transmit, the touchscreen is used to monitor outgoing video and so the buttons are no longer visible - to turn the transmitter off, simply touch the screen in the same area as the TX button.

• Why doesn't MPEG2 mode work?

MPEG2 mode currently does not work if you have an analog capture device connected (it upsets the numbering of video devices). If you want MPEG2 mode, unplug the analog capture USB and reboot - it should work. It is hoped to overcome this issue with a software change shortly.

• What do I need to receive a Portsdown transmitter?

As the Portsdown transmitter when fitted with the filter / modulator card will run normal bandwidth modes you will be able receive it on any Free to Air (or FreeSat) Set top box. However, when it is running in RB-TV modes or in Ugly mode without the Filter Modulator card you can only receive it using Minituner - the specially developed hardware and software - see here for more details.

• What is the Portsdown reciever?

The Portsdown receiver will be a development of the Minitune receiver with a simple user interface and new hardware giving continuous coverage from 140 to 2650 MHz meaning we no longer need receive upconverters to cover 146 and 437 MHz.
