?Just my 2 pennies worth. Interfacing and controlling your FT847 remotely is very simple, however piping audio back and forth over the internet ….. tough….. very tough.

For my satellite setup I listen to my FT847 and co tell it with a Pi controlling the intermediate link.

?Curiously enough I actually made a short video this evening for a lecture.

Using the Pi for VPN using OpenVPN and sharing the auth key with your mobile or VNC for more hands on. X11 or VNC-tight can do that for you with realVNC on phone or remote PC.

? Ok I use PSTRotstor and my phone to click on my rotator in PST and direct it but you could use the TCP feature built into PSTrotator and open a port in your router but unfortunately PSTrotstor doesn’t accommodate anything other than Windows. In that case you need FLdigi and FLRig.

?Ok now the big headache. Audio. I personally use Skype on my remote PC and simply phone myself over VPC and my phone rings I mute the mic on the phone as ?it ?tends to clutter when full duplex audio is in operation and causes drop outs due to a noise cancelling feature I’ve not managed so turn off no matter if you turn it off in Skype. The result is is ok streaming audio but you could cheat and press TX and then use an audio interface such as a Signalink SL-1 (that’s what I’ve used) and then select the microphone in Skype to output the audio to the front socket on the radio. The SCU-17 will only work for UHF and VHF as the 6 pin socket and TNC was never designed for HF so you’re left with the front socket for HF. You could risk linking the speaker output of your PC or PI direct but that’s fraught with RF loops and feedback.?

?I would also build a TOT also with a simple timer bought from the far east set it for 2 minutes. This way if comms drop all together your not key down until you regain connection. There is an inhibit built into one of the sockets (I think it’s the standby socket)? But need to look as I inhibited mine with a 4.7k resistor if my memory serves me to stop all TX while I’m monitoring remotely.

?The alternative is to Pay for a license for RealVNC’s audio streaming service. It’s proprietary and does not use RTSP according to RealVNC.?

?Lastly, get Adobe encode and use the PI as a RTSP server and encode the audio on the fly. You will have to do the same at the other end and have half duplex communication which gets really sticky. If there was another way of streaming audio over the Internet….. I would have found it but even I’m stuck for a solution.

Will post a video soon.

?Hey All.

I just picked up a 847 second hand (obviously) and want to use it at a remote location if at all possible. I have been scanning this group for links and suggestions for interfacing ideas etc. Idealy I would like to use a RPI at the remote location but open to any ideas. What is the easiest complete solution to buying an interface and cables in the one spot?
