SDC Remote

[Oscar Luis EA1DR]

Good morning and greetings to everyone.

I recently acquired a FlexRadio 8400, intended exclusively for remote operation from my second QTH. At that location I have Internet access via Starlink, which initially caused me quite a few problems getting the radio to connect to SmartSDR.

After several unsuccessful attempts, I contacted D4Zero VPN, and I must say that Mike’s support was outstanding. In a very short time he had everything perfectly configured and working. In approximately one hour the system was 100% operational. It has been a real pleasure dealing with such professional, friendly, and efficient people.

Now I have a question that I have also mentioned to Yuri:

Is there anyone here with a setup similar to mine who is using SDC remotely, exclusively in remote mode? This is something I would like to implement, and I’m interested in knowing whether it works correctly and reliably.

Any information or shared experience would be very welcome.

Thank you very much, and have a great day.

Yes — SDC works perfectly over a local VPN, basically as if the radio was sitting in your own LAN at home 🙂

What kind of latency do you get over Starlink?
That’s an interesting number, especially for SO2R and digital modes.

In practice, the only thing you need to do differently is to manually set the IP address and UDP ports of the FlexRadio 8400 in SDC. Everything else works the same as on a local network.

If you need any help with the setup, just let me know and we’ll sort it out.
