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?
Remote site is LTE-service and I don't know exact, local is 100 Mbit/s down/10Mbit/s up. Owner of the radio says it works fine when he tries. What is confusing for me is that if I ping the remote IP outside SmartSDR, I get 10 times lower response time than what SmartSDR reports. Is there maybe something I need to modify in my client side router/firewall?
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.
