	Having updated the firmware and confirmed that it was working, next was the start of a massive learning curve…What would I need to use to generate some 'digital stream' with video in it? What software should be used? How does the stream get from the PC to the SDR? How do you set all the parameters needed to generate DATV? How do I get video from my phone camera into the PC? The list of questions was growing the more I looked into this stuff....

		+
		+	BTW you may be wondering how you update the Plutos firmware if you are running it via a LAN connection, well, its pretty simple. Download WinSCP, configure it to point at the IP Address of your Pluto, copy the pluto.frm file up to /root (root home directory). Once done, SSH into the Pluto (download Putty or similar) then execute update_frm.sh pluto.frm this will extract the firmware and update the internal flash memory. Once done, type 'reboot'. When the Pluto comes back up, it'll be at the firmware level just uploaded; this saves having to plug the Pluto into a PC via USB and using the normal firmware update method.

	The relay contacts can be used to control a power amplifier. This control is your problem, but remember the small PCB relay can only switch 500mA and the optocoupler considerably less.

	In the final system iteration here at the M0EYT ground station, I'll use a good de-noised 5V PSU, the PLUTO will go in a metal box for mechanical stability purposes, and I'll mount SMA sockets with back to back connectors that have the same hole spacing as the SDR, this should ensure that nothing gets broken.

	The PLUTO Firmware now supports a PTT output so that when a valid RTMP stream starts, the PTT pin changes state to allow amplifiers etc to be keyed. PTT comes from GPO0 circled in red below;		The PLUTO Firmware now supports a PTT output so that when a valid RTMP stream starts, the PTT pin changes state to allow amplifiers etc to be keyed.
