The Portsdown 2018 DATV system has been designed to provide an easy way to “get on air” with Digital ATV at a relatively low cost covering all of the commonly used modes so enabling it to be used on ATV repeaters but also for RB-TV Dx working.
The filter modulator card and DATVExpress card described on these pages are obsolete and new build should follow the Portsdown 2019 build instructions here.
This user guide is in a number of sections which cover detailed descriptions for hardware and software, how to build and configure the system, some advanced features and an FAQ.

You can control the Portsdown transmitter in one of 2 modes: by the use of the touchscreen or through the console using a second computer.
- Touchscreen mode How to use your Portsdown transmitter using the Touchscreen LCD only
- Console mode Use this mode to configure your Portsdown and change pre-set configs (such as SR and Freq) used in touch screen buttons.

Advanced features
The Portsdown is not just a DATV transmitter but has several advanced features which are or may be available in the future:

On line support / social media
There is a Portsdown area on the BATC forum where the BATC core team and wider ATV community will answer your questions and posting results of the latest builds and on air tests. https://forum.batc.org.uk/viewforum.php?f=103
Note that the BATC core team do not regularly visit Facebook pages - time is just too short to monitor everything and it's not easy to follow threads on Facebook. If you need a question answered please post on the BATC forums first.
Additional information
Filters and driver amplifiers are not part of the Portsdown project but VERY important
The Portsdown user's community including a map showing where user locations
