Softether - no waterfall showing

Mike va3mw

For those of you using Softether for your remote connection, have any of you had SmartSDR functioning, but no panadapter or waterfall showing? I know that TCP 4992 UDP 4991-4999 are the ports that SmartSDR uses, and I have the VPN setup to access my entire subnet with no restrictions. It is seems like ports 4991-4999 aren't making it into the tunnel. Mike va3mw

No trouble here, but I'm using port 5555.

Thanks Doug, Port 5555 is for the initial connection and all the data runs 'tunneled' through that port. On the other end, it is unpackaged so that it is back on those ports I mentioned. But, let me ask, you didn't do anything special other than the basic setup, correct? Mike

No, pretty much the stock installation. If you have a good high speed connection the panadapter and waterfall looks great.

I use native Windows PPTP to a PPTP VPN server at home in the router. It works better on some networks and not as well on others. The first indication is the same as described above, no panadapter, waterfall or audio.

On my Verizon hotspot it usually works better than at McDonald's on their WiFi.

In general I've blamed my upload limit at home of 768 Kbits/Sec. but that doesn't explain why it works sometimes & not other times.

Slowing the Frames Per Second & Waterfall Update Rate helps but doesn't eliminate the problem all of the time.

I don't think it is a bandwidth issue. I have 4M up and I can see running iftop on my firewall that it uses less than 1M normally. It sounds like a firewall issue, but I am not sure exactly where it is happening. Time to dig out wireshark I guess.

I have 30 MBits up and down with a fiber service, however depending on network load, I can still have problems. The audio stops and/or the panadapter quits and starts in spurts. The latest 6000 series software includes a bar graph and a pop up giving you an error count.  I need all bars to be green.  Things start going bad when the yellow bars appear and when they turn red you can forget it.  What color are your bars when this happens?

Here it's pretty much as you describe it. The quality bars appear to track latency. Latency seems to track bandwidth available versus update speeds of the waterfall and to a lesser degree the refresh speed of the panadapter.

Within my LAN a 2.4 GHz. WiFi connection plus a 2.4 GHz. Bluetooth mouse connection interfere with one another exhibiting the same problem. This has led to my initial conclusion that there is a bandwidth component to this or at least a latency issue. When I switch the WiFi to 5 GHz, the problem goes away . The LAN removes my limited 768 upload from the equation.

What I can't figure out is if this a flex 'throttling' issue or something else.
