I just setup CW skimmer for working remote over internet. 

It looks like DAX IQ needs high bandwith, because everything is working choppy... Is the upload on radio side to low?

I don't think that DAX I/Q has been optimized for working remote yet,  and I would bet you will need much more band width ,  you can check the network performance in Windows Task manager to see the throughput of your PC nic connection.

My RX audio was choppy as you said. I had to turn offFAX IO the rx was fine on FT8 one slice. Still working on it for TX.

I have checked the upload speed on radio side, just 4mb/s. So i think this is the problem ...

I did this  test and came to the conclusion that the choppy audio is due to the rapid screen updates that have to happen with CW Skimmer.  I have used TeamViewer, VNC and Remote Desktop and Skimmer running on a local PC (not the remote PC).

It gets better if you reduce your upload screen resolution and this with running CW Skimmer local to the radio.

As soon as I start Skimmer running locally, my upload data rates max out at 2mb/sec, which is my max on my remote.  This is not the fault of Skimmer or DAX IQ.  If you look closely at the network traffic you will see that it is related to the Remote Screen updates.

If you are running DAX IQ remote, than you are maxing out your upload.  

I long ago decided that running a PC remote and on the same LAN as the radio was by far the most reliable way to operate remote.  Since we have no idea what goes on in the cloud between the 2 sites, we are not able to control it.  Every ISP does some sort of traffic shaping and it is 100% out of our control.

Hello Mike


Many thanks for your extensive reply. Can you detailed describe your remote station setup? I consider to place a PC on radio site to control my rotor and UltraBeam and approach this with Teamviewer.

But I understand you operate more from this PC on the radio site?


In the meantime, I am in negotiation with my Internet Provider for higher speed upload
