Questions about improving IMD

The APACHE LABS transceiver (OpenHPSDR) has a predistortion function, which improves IMD.
Is there a function for improving IMD in the FLEX - 6000 series?

    The way the 6xxx radios are designed is in it self is a function of improved IMD. The Flex can achieve at least 40db, very respectable indeed.
    Flex has plans to introduce there version of what Apache is using in a future version.
    When? we just don't know, but because of the IMD performance we now enjoy there has not been a need for it. But it would be nice to see.

    As you know the hardware in the Amp is pre distortion ready and the Amp has been tested with the Anan using pre distortion. And the radio's hardware are ready as well.

    That is were things stand now.

    Ya, the 40m voice group I sometimes join is all about this pure signal stuff.  It will be nice when it all comes together.

    But I like to either gain access to my friends Flex 6X00 or I use a remote and I tune to myself and transmit and look at the pan on the remote.   For the most part, unless very close the IMD is not visible.
