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.
- 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 receiver?
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.
- Can I use another touchscreen LCD?
Maybe! The Portsdown project only supports the Waveshare screen - that doesn't mean to say others won't work but we can't help you if it doesn't.
- Who are the Portsdown team?
The Portsdown team are just BATC members doing this as volunteers to support the ATV community. As such, it is not their full time job and they are not being paid. If you have a problem, question or comment, please do not contact them directly but use the BATC members forum and do expect an instant response!
- Do I need to know about Linux or other clever computer stuff to get Portsdown running?
NO - the Portsdown transmitter has been designed to "work out of the box":
- You do not need to do anything other than follow the initial set up guide
- Do not load any device drivers
- Do not tinker with Linux commands
If you do, we don't have time to support you and will just advise you to reformat your SD card and start again!
- 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.
