PGXL and TGXL being used with OEM HF (non-Flex) radios

Mike-VA3MW Administrator, FlexRadio Employee, Community Manager, Super Elmer, Moderator admin

Hi All

We are doing an informal survey to see what OEM (non-Flex) radio you are using with your PGXL.

Can you take a moment and comment by replying:

  • What OEM radio
  • What CAT mode did you select (or, are you using RFsense)
  • Your TX Delay (it should be 20ms or better)
  • Your TGXL version
  • Your operating style (FT8, SSB, CW, Dxing, Contesting, etc)
  • Any other comments


Again, comment in this thread please.



  • Hi
    I am using a Kenwood TS-890s and Flex 6600

    The Flex is on port A of the PGXL and Kenwood on port B I have a 1x3 TGXL also
    so it is on port A for both radios with manual coax switch to select the different radio I want to use

    I use Cat for the Kenwood 890 and of course Lan control on Flex
    PGXL controls the band information on the TGXL

    Because I have a 1x3 TGXL I have to disable the Flex on port A and enable Kenwood in settings of
    TGXL when using Kenwood and enable Flex when going back to Flex 6600

    TX delay is set for 30 ms on Kenwood 30 ms on Flex

    TGXL version is 1.1.20 PGXL ver is 3.7.32

    I operate SSB some CW with Kenwood and Flex SSB and some FT-8

    I operate some contests with both Radios

    Thanks both!

    BTW, the recommended TX Delay is 30ms and that is something that is set in your radio.

    For those that don't know what TXD is, it delays the RF by 30ms before sending it. This allows all the RF devices downstream to move from RX to TX. 20ms might be enough but you should be fine at 30ms. And, we doubt you'll even notice the difference.

    For those using a FlexRadio exciter, there is a much more robust communication between the radio and the downstream devices. The radio actually talks to other devices to see if they are ready to transmit.
