internet speed for remote K3S

I will soon be building a remote control station about 20miles away. Both
stations have access to broadband, but what speed will give satisfactory results? tnx and 73 David G3UNA ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |

Both > stations have access to broadband, but what speed will give satisfactory > results? My experience operating remote is with a K3I/O-mini and Remote Rig interfaces. My station is 1,250 miles from where I’m currently located. The K3 transmitter site (Southeast Georgia) is in a rural setting that uses DSL with a downlink capability of about 20 Mbps and uplink capability of about 1 Mbps (the fastest speed available for residential customers). The control location (Boston) with the K3/IO-Mini uses Comcast/Xfinity which provides a downlink capability of 90 MBps and 6 Mbps uplink. With this setup I have no problems using the K3/IO through the K3/IO-Mini with excellent audio and instantaneous management of the radio. At the same, I’m using web-based interfaces (RR-1216H) to control the KPA500 amplifier and Green Heron RT-21 rotor controller. One of the advantages of Remote Rig is that there are various audio codec options available which can be set depending upon how much bandwidth is available. My remote rig setup uses a relatively low audio setting (16 KHz) but the audio sounds fine to my ears and I have no problem with this setup. I haven’t experimented with higher audio settings in part because I have other devices feeding data through that 1 MB Uplink as well. Bottom line is that if you have true “broadband” at both locations, I wouldn’t expect any problems.

Hi David, I've never done this, but reading from what others have done, I suspect that latency may be as important as speed, especially if you want to do CW contesting or break a DX pileup. 73, Jim K9YC ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |

My experience is exactly that; look out for latency; that is the
killer. Yes you need a minimal speed that is pretty good, but latency is a big issue; for example the satellite based ISPs are useless for this; adequate for streaming movies, etc. but latency is way to high... 73 de Dave, W5SV On 9/1/18 3:30 PM, Jim Brown wrote: > On 9/1/2018 12:38 PM, David Cutter via Elecraft wrote: >> Both >> stations have access to broadband, but what speed will give satisfactory >> results? > > Hi David, > > I've never done this, but reading from what others have done, I > suspect that latency may be as important as speed, especially if you > want to do CW contesting or break a DX pileup. > > 73, Jim K9YC > > ______________________________________________________________ > Elecraft mailing list > Home: http://mailman.qth.net/mailman/listinfo/elecraft > Help: http://mailman.qth.net/mmfaq.htm > Post: mailto:[hidden email] > > This list hosted by: http://www.qsl.net > Please help support this email list: http://www.qsl.net/donate.html > Message delivered to [hidden email] -- שָׁלום עֲלֵיכֶם - עֲלֵיכֶם שָׁלום ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |

Agreed, My Hughes net satellite service was a bust for it....

I run remote to W7RN [near Virginia City NV] from Sparks, NV ... maybe
50-60 km road miles away. Trace Route shows that most packets go through Sacramento, some through San Francisco, some through Los Angeles. Ping times average about 35-40 ms. BW required by RemoteRig is much lower than I expected, maybe around 30-60 Kbps both ways. At 40 ms, the latency is just noticeable if I spin the Big Knob really fast. The RRC 1258 is simplex, no QSK. These data are for CW, I almost never use SSB, and haven't tried RTTY yet. One of the other users runs FT8 all the time, very successfully. We use Teamviewer to view and control the station automation, it seems to consume around 300 Kbps under most conditions. The RRC CODEC has a variety of options, some requiring more BW than others. Web cams on the monitor can really increase the BW requirement. They usually work in a differential mode, sending only the changes from the last frame. A tree outside the window in a little breeze will make a huge number of pixel changes in the shack lighting and the camera really sucks up the BW. Packet-level reliability is far more important than raw speed. If there are other devices on your sub-net with high throughput, or if your WAN is unreliable at packet-level, it may be impossible to operate. 73, Fred ["Skip"] K6DGW Sparks NV DM09dn Washoe County On 9/1/2018 12:38 PM, David Cutter via Elecraft wrote: > I will soon be building a remote control station about 20miles away.

Not trying to hijack thread only broaden it...
Has anyone used a cell modem on one side with modest BW, to use K3/0? 73 Dean K2WW .

Dean,
The use of a cell modem service on the radio/station end is a big problem, if you run any software or devices that require a public-routable ip address or port forwarding on the router. See for example: http://www.remoterig.com/forum/index.php?topic=2768.0 Search for terms like double-NAT The cell service is very unlikely to provide this. There are complicated work-arounds if you have the internet networking savvy to setup VPNs and such. If you engage in discussions with the service provider, there may be an upgraded "business class" service package that provides the ip addresse and router function that will make your life easier.

It's a "sometimes" sort of thing with my Verizon 4G android. Packet
routing on the cellular network seems to be highly variable in real time ... in the three times I've tried it, it worked sort of OK once, not so good the other two. Beware, remote operation can eat up a data allocation faster than a teenager on Instagram. 73, Fred ["Skip"] K6DGW Sparks NV DM09dn Washoe County On 9/2/2018 7:29 AM, Dean L wrote: > Not trying to hijack thread only broaden it... > > Has anyone used a cell modem on one side with modest BW, to use K3/0? > 73 > Dean K2WW > ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |
