    Is your Winkeyer is connected to the USB port on the 6700?

    Hi Tim, thanks for coming back.
    No, should it? I've always been using the CW key input pin on the connector in the back.

    No, it should not.  I couldn't tell definitively from your issue description.

    Is the 4-port a powered hub?  And is it getting power from the radio or externally?  If from the radio and you can use external power, I'd try that and see if the issue improves.

    The 4-port is a powered hub, yes. It is using an external power supply.

    Hi, I use the same set Up with an external Winkeyer . USB output to PC and keyer output to front CW keyer of 6700. Works very well in all speeds.

    Frank - Is the keyer connected to the front KEY jack or are you using the keying lines on the rear ACC connector?

    Hi Tim, Rear ACC connector.

    Hi Frank,
    I wonder if you can determine whether just one of the radio USB ports is causing the issue.  And if so what is the configuration of that USB port ( i.e. serial, BCD, bit).    

    I don't use Winkeyer but checked so see if I could reproduce the issue by using a hand key connected to the rear acc connector.  I have a serial USB connection to my amplifier and BCD connect to my antenna switch which were both active for the test.  I set the RF power to zero and tried lots of dots' etc but could not reproduce. 

    Also wonder if your issue also occurs when the RF Power is set to zero....or only when outputting power.....that might be another interesting data point.

    Hi Al, I will do more experiments.

    So far tested: Issue is the same when using the front Key jack. It also happens when the power is set to zero. 

    I wonder if it has to do with the fact it is a FTDI four port adapter as apparently nobody else has the issue. I just know it is reproducable when switching the USB cable function on or off.

    How many devices are connected to the USB hub?  Can you try connecting each device individually to the radio without the USB hub and see if the behavior persists?  The ol' divide and conquer technique of troubleshooting.

    Hi Tim, I don't have a USB hub connected and never had. 73

    The USB 4 port FTDI serial port adapter is not a USB hub?  Can you give me more details on it?

    OK.  I wanted to look at the specs on it just to see if there was something that caught my attention.

    Fwiw.
    I Was using the Gearmo ftdi usb to 4 port serial on the flex 6500 usb to the spe amp. Quite frequently it would drop out i would get error message in spe. This would happen so fast. I couldnt quite catch msg. I replaced gearmo 4 port serial wth ftdi cable flex sell. Got it from mouser. Since then no issues with flex usb and spe. Rock solid no dropouts. So would have been problem with Gearmo

    Have you tried using one of the FTDI cables that we recommend? See the USB Cable Interface Guide here: http://www.flexradio.com/downloads/usb-cable-interface-guide-pdf/.  Also, see the serial cable we carry in our cart here: http://cart.flexradio.com/USB-to-Serial-adapter-for-the-FLEX-6000-series_p_1002.html.

    Hi Eric, thanks for coming back.

    I've now exchanged the 4 port adapter by two individual FTDI adapters.

    I can confirm the issue has gone when switching to two individual FTDI cables.

    The FTDI cables really should all be the same from a hardware point of view as long as  they use proper and original chips.

    And the question still remains, how an issue on the USB side of things could possibly affect CW generation. So even though the problem is gone you still might want to have your developers look at it.
    Anyway thanks for the input guys and I am glad I'm back to smooth and nice QRQ.

    Simple question on Winkeyer usb and flex6400 and SmartSDR iOSX: I connected Winkeyer to Mac USB and then to 6400 with this cable

    IMG_4422 copia.jpeg

    as suggested by k1el, to the #5 Morse key socket on the back of 6400, but my key - connected to Winkeyer itself on paddle socket- is not capable to reach 6400, while Winkeyer is reached by MacloggerDX command strings like F1 "CQ CQ...", but the string is not passed to 6400.

    Obviously if I connect the paddle to 6400 directly on #5 Morse key socket - bypassing Winkeyer and disconnecting the above cable - everything works well but Winkeyer does not communicate with 6400.

    Where is the mistake, can somebody help me from FlexRadio side?

    Thanks
