Remote problem

Goran SM6PPS

I am trying to use another owners radio to test SmartSDR 2.3.9 on Windows 7. If I ping the remote radio in a command prompt, I get around 40 ms. When connected with SmartLink, Network Diagnostics show around 300 ms and status shows up as poor. I can hear audio and control the radio, but the spectrum display doesn't work. Dropped packets is around 6%. Any ideas of where to look for the problem?

No, at remote no router changes needed. Your speed is OK but what's the LAN speed at radio side?

Mostly - if waterfall not work - it's a LAN problem.

Maybe Mike from FRS can answer your question

LTE Speed - why do folks insist on running remote setups with Cellular services & LTE services, your just asking for issues!. Then they blame SSDR software or the Rigs Ethernet port.

I suspect the reason for the difference in times is the size of the packet. When you use the “ping” command with just an IP address the default size of the packet is 128 bytes (if memory serves me correctly). Where as when SSDR is communicating with the radio it will be using much larger packets. Larger packets, longer times.

I haven't had any issues running the Flex with smart link at any point, But then again I don't try and wouldn't consider to use a cellular internet carrier to host such things. Fiber here with FTTP.  even when I ran the 100/50 connection never had an issue, and that includes 4 servers and a VOIP systems along with 4 kids streaming or playing on-line games, I recently moved to 500/200 services, as I'll be taken on a more servers and clients.  It just surprises me how many folks try and use LTE or 3G cellular services for remote access and then blame Flex that it doesn't work. It's been my experience along with others that Splashtop remote works better then Teamviewer for audio and most other applications, and the cost is much less!, Using it with around 200 clients here and haven't had an issue.

I have been using 4G LTE at my remote Flexradio for two years now. It has worked flawlessly. But I have no alternative. Yet anyway. In rural areas it is still the only way to access broadband internet services. I guess we will have 5G before fiber. 73 Kari SM0HRP

Hi Bob, thanks for info about the Vita 49 packet sizes. I think this could be the reason then why I don't see any spectrum. Most Vita 49 packets arriving on my side (client), is less than 150 bytes. Some are 1002 and even fewer are 1358 bytes. I do not get any Vita 49 packets larger than 1358 bytes. So if they are sent from the radio, it looks more like this is the issue rather than speed as some people seems to indicate.

I always find my remote connects through LTE are always reliable and much better than public LANs. I have tried many of them in restaurants, bars etc. They all have issues such as no waterfall, freezing and long drop outs. I have none of these issues with my unlimited cellular service (AT&T).

I start a new thread to focus "Fragmentation issue w SmartSDR 2.3.9 and not w Smart SDR iOS" on the issuse.
