+**rpidatv** is a digital television transmitter for Raspberry Pi 3.  The core of the transmitter was written by Evariste Courjaud F5OEO and is maintained by him.  This version has been developed by a team of BATC members for use with an external synthesized oscillator and modulator/filter board to produce a signal suitable for driving a high power amateur television transmitter on the 146, 432 or 1296 MHz bands.  The idea is that the design should be reproducible by someone who has never used Linux before.  Detailed instructions on loading the software are listed below, and further details of the complete transmitter design and build are on the BATC Wiki at https://wiki.batc.tv/The_Portsdown_Transmitter.  There is a Forum for discussion of the project here: http://www.batc.org.uk/forum/viewforum.php?f=103

+Our thanks to Evariste and all the other contributors to this community project.  All code within the project is GPL.

-- Before you remove the card from your Windows PC, look at the card with windows explorer; the volume should be labelled "boot".  Create a new empty file called ssh in the top-level (root) directory by right-clicking, selecting New, Text Document, and then change the name to ssh (not ssh.txt).  You should get a window warning about changing the filename extension.  Click OK.  If you do not get this warning, you have created a file called ssh.txt and you need to rename it ssh.
