Re: FT8 and ALC
¿ªÔÆÌåÓýNo! If I understand you right. You must set your radio settings how you want. This is not the same power as on the software. There is a scale you adjust this to change the audio level. I think it¡¯s called the power level and it will bring your ALC down. You can have the ALC showing but set it low as you say or just disappearing but that¡¯s your choice, personally I have mine showing a couple of bars?Sent from Jeff M0UHF?

Re: General Cat control
¿ªÔÆÌåÓýyou know you need a null modem type connection correct?? which cable type are you using?

Hey all. Tinkering around with an old (but newly aquired) 847 and doing what I like best and hooking up computers etc. I dont seem to be able to get any cat software to comminicate with the radio. is there a menu item somewhere that I have to turn on the cat control option in the radio? I see mention here and there googling it about a C+ or C- but not sure where that is. |

Re: Preference to an interfacing system
¿ªÔÆÌåÓýYou should check the serial number of your 847 against the version chart (somewhere on the 'Net - I forget where).? The early versions could only be driven from CAT, not read from.? Not being able to see what the radio config, etc. is can make remote use a bit more challenging.Greg? KO6TH Spence M0STO via groups.io wrote:

Re: Preference to an interfacing system
¿ªÔÆÌåÓýSomething as simple as a USB to RS232 adapter and then dev/ttyUSB0 normally? My interface of choice is rather expensive but very reliable but you can get them from the internet here in the UK second user and quite cheap and that the BrainBoxes US-27501 ? Remember the FT847 is Null modem connection to RS232 ports. You could use the Yaesu SC17 but that will only help you for VHF and UHF but will give you a standard com port without RTS and DTR and also create another port (uses same hardware connection but enhanced with RTS DTR pull-ups for PTT.). Mine is Com7 and Com8. I can¡¯t see any reason building a 6 mini din socket and that can connect to a Yaesu 8 pin microphone socket. Yaesu advertise the SCU17 for just about every radio except the FT847 probably because it¡¯s tricky to get it working with HF. Nearly all data ports on the FT847 are dedicated to VHF and UHF. Eg: 6 pin and 3.5mm data TNC. ? How this helps. Had to remove the video as I wasn¡¯t sure it had any personal information in it¡. Will post again but I just Skyped myself and listened to GreenCube data but obviously can be extrapolated for any satellite. De Spence M0STO Sent while portable! please excuse typos.

?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.De Spence M0STOSent while portable! please excuse typos.On 19 Dec 2023, at 21:52, ft847@... wrote:?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?
