    I had that problem with running a long 50' Ethernet cable. I had 6600 in storage bay of RV and maestro inside and got the same thing. I moved radio inside with a 6' Ethernet and it went away.

    Hi

    Sorry to hear you are having issues.  There are a few things that help diagnose this, and it is not normal.

    As a test, take a LAN cable and connect the Maestro directly  to the radio without a switch involved.  Run the same tests and if the VFO lags, then open a support ticket.  This keeps the test very simple.

    If not, then look external to the radio.  

    I have seen issues with Gigabit switches buffer way too much data and this can contribute to the issues are seeing.  Can you test on a 100M switch?

    You also didn't mention which version of SmartSDR you are using.  Make sure you are using the latest V2 or V3.

    Lastly a bad cable will cause this.  I have a bad 3ft cable that works, but not well.  I keep it well tagged for testing.

    As for production runs, there are only 2 and you can tell by the location of the power switch.  A model is on the top left and the B model is on the side left.    The serial numbers are not sequential so you can't tell by those.

    Let us know how you make out.

    Hi Steve,
    Unfortunately, I do not have any access to another Flex radio than mine. If someone can grant me a temporary access to 6700, it will be just fine.
    Any volunteer available for tests with me?
    73, Todor

    A few other things.

    If the Maestro works with a Single LAN cable but fails on the switch, then you may want to check to see if Jumbo frames are turned on and as a test try turning it off.  If it lags when connected to a switch, that something in the switch is slowing you down,

    Unfortunately, not all switches are created equal.  As well, questionable Lan cables result in many retries on the data movement.

    The key part is the Simple LAN cable test.  Don't go any further until you have tried that.

    Mike, where is the " jumbo frames" setting? That's a new one on me. James WD5GWY

    So, if I read the thread correctly, jumbo frames will not be a help, correct?  Also, in my case where it runs fine for the first 5-7 minutes (and I'll add more in a few moments) that would seem to rule out the need for jumbo frames.

    Also MTU jumbo frames can be adjusted now in version 3. Check under advanced settings in the radio settings tab. And also check this article which explains how to set it from the network side in a PC: https://kb.netgear.com/19863/Ping-Test-to-determine-Optimal-MTU-Size-on-Router

    Todor - I reduced the settings (AVG and FPS) and, indeed, it does help the problem.  Unfortunately, it makes the display difficult to use due to the visual effects created.  In my case, AVG seems to have more effect than FPS, however it is not easy to quantify due to the symptoms clearing briefly (for about 5 minutes in some cases) and then the lag returns.  Here is how my testing went:

    Power on after 10 days of no use (away from home)
    No lag for 7 minutes, then the familiar lag returns.
    Reduce AVG and FPS to 20% - freq readout tracks much better, but introduces other issues.
    Switch Maestro from enet to 5G WiFi - tracking is correct again, but after 5 minutes the lagging resumes. 

    I have yet to test with an ethernet cable directly between Maestro and 6600.

    Mike, the problem exist even when the Maestro is connected directly to the radio. I tried multiple cables, always same result.

    Thank you for your prompt reply, Duane!

    I am looking forward to hearing from you when you test the Maestro with direct cable connection to 6600

    Hmm, could it be the problem lies with the wifi connection to the radio/PC? Have you swapped them cables out? Either way good luck with it.

    Reset the both the radio and Maestro and see if operation improves.  One at a time.
